Sorry we never replied to that, but the problem was found to only exist on sine sweeps and too complicated/risky to fix for this release.

Perhaps this has been an issue before this version, but I have tracks of silence that are being encoded at 20-40 kbps. This is in contrast to songs that have some sound at the beginning and then 3 kbps silence for the rest. Minor issue, considering very few artists have tracks of complete silence, but something to keep in mind nonetheless.

In any case, I'm currently ABX'ing away.

Hmmm... it doesn't work for me here unfortunately. I can issue the -help command but when I try to encode something it just crashes and Windows error reporting window pops up. 

Are there some dependencies that weren't required with the previous version?

Works with foobar2000, but not perfectly.

I converted a 5 minute WAV file to m4a (96000Hz Stereo -q 1.0 ),
played it with foobar2000, the file length is wrong ( 15:45 ).

WMP, iTunes, Quicktime, MPC do not have the similar problem.

You probably need to update foobar2000, because older versions had an issue with the timescale for the iTunes gapless data.

It should work on machines with only SSE (and without any enhanced instruction set for that matter). You should be able to extract some more info form that WER window.

Yeah, I think so. Although it seems that even that version it is not completely fixed yet (for your case it seems to be ok): For HE AAC files foobar2000 still seems to use the wrong timescale.

Post by: jmcguckin on 2009-12-25 17:10:04
well, I'm still using foobar2000 0.9.4.x (for UI reasons), and I have not had any "time display" issues between Nero and iTunes, so that seems to be a non-issue for older versions of foobar2000.

now that I've done a fair amount of testing, I have a quick question-  I've noticed that the quality scale was re-mapped to where -q0.50 once again returns files at an average bitrate of ~175kbps (over my entire library), and what I'm wondering is whether there was extra tuning done to any specific integer values (i.e. if I'd notice the same behavior at -q0.5x or -q0.5xx as I would at -q0.5)... the average bitrates of my files don't seem to fluctuate nearly as much as they used to (for instance, with v. 1.3.3, old max ~ 201kbps vs. new max ~ 192kbps and old min ~ 75kbps vs. new min ~ 145kbps), and I was just curious why there was such a noticeable change.

If I understand this correctly, a non-SBR-aware decoder can't gaplessly decode your files?

No, you have to use the LC AAC samplerate from the audio specific config, so SBR has no influence.

It seems that high sampling rate files have the file-length problems,
I did some quick tests, 8000 Hz ~ 48000 Hz(mono and stereo) is OK,
88200 Hz and 96000 have the bug.

I had initial issues with my LG Chocolate Touch now showing track tag information until I copied the tracks off of the member card and onto its internal storage (a paltry 1GB).  Kind of strange but that is one more device which Nero works with without issues.

Hey Korn, have you tried editing the tags with another program yet?  The LGs are picky as hell.  Tags that Winamp created with CT AAC would work (occasionally) but if modified with Mp3tag, or others, they'd rewrite the genre field where the phone couldn't read it.  What information wasn't showing for you?  I've only had problems with the genre field.

iTunes written tags seem to be hit or miss.  For example, I had some iTunes AAC files where the tags didn't show up, Nero 1.5.1 files where the tags showed up without issues, iTunes Plus purchases with tagging issues, and now I am having issues with some Nero 1.5.1 files.  I know that this isn't Nero's fault but rather LG's software implementation for the portable music player (or whoever makes it).  So I have yet to find a combination that was solid.  I edited some tags with foobar2000 and they didn't show up either.  The tags are very basic on my LG Chocolate Touch.  Artist, album, and genre are about all I have found.  This cellphone came in on the 24th of December (2 days ago) so I am still in the process of learning the ins and outs.  AAC playback goes off without a hitch whether I am working with LC or HE files but tag support seems to be all over the place.  I am not sure why it is having issues with iTunes standard tags as that seems to be the implementation that everyone else is using.

Just converted again other FLAC files with v1.5.1.0 to be sure. Sadly the same thing: no CDEC tag in Properties of fb2k conetext menu. This I've seen with both foobar2000 v1.0 beta5 and beta6 on Windows 7 64 bits. I use the default builtin converter (the one with the slider) and target quality VBR. When changing to custom I see this command line:
Quote
-q 0.55 -ignorelength -if - -of %d

With Nero v1.3.3.0 encoded files never had the problem,CDEC tag was always there, also with fb2k v1.0beta6:
Quote
<CDEC> : ndaudio 1.3.3.0 / -q 0.55


Edit added:
I just checked with command "neroaactag filename.m4a -list-meta" and cdec meta entry is not present for v1.5.1.0 encoded files, as opposed to v1.3.3.0 encoded files:

cdec = ndaudio 1.3.3.0 / -q 0.55

I confirm the findings of lvqcl: with Nero v1.5.1.0, CDEC tag is not there when there is one or more tags available in source file. Nero v1.3.3.0 shows the opposite behaviour.

Post by: dgauze on 2009-12-29 22:50:23
I have converted many files from the command line, and they all have the CDEC tag. It shows up in foobar 0.9. The source files are FLAC with vorbis comments.

Could it be a that the foobar converter removes the field upon conversion?

EDIT: The encoder deals only with PCM data. The tags should not make a difference.

Not sure if it is of any interest for anyone but I have tested Nero AAC 1.5.3.0 for more than 1 hour on the Harlem & Autechre samples at various settings 0.35/0.40/0.55/0.65 ... the result is rather dispointing as I found nothing really new: to my ears the transparency point didn't change (on these two samples only indeed). I haven't tested V1.5.1 Vs. 1.5.3, I have only tested 1.5.3 separately against lossless, so I don't know if there is a marginal improvement/regression within the artefacts I hear. Honestly I expected more after a year without a release but maybe I simply expected too much (I was secretly hoping that 0.40 would be near transparent which was maybe a little irrealistic I admit, transparency at ~128Kbps VBR will remain a myth) & maybe the public listening test will prove me wrong (but even if it does I don't really care as I trust myself more ...). Maybe the improvements are not where I am listening too, simply. (More likely)

I will publish the results with logs in my listening test thread when ready, the only reason why I haven't done it yet is because I don't know if I will test it more or not. The test page normally includes Abfahrt Hinwil/Castanets/Kraftwerk samples, but I am lazy... It is highly possible that I will focus on if there is or not an improvement/regression within V1.5.1 Vs. 1.5.3 at 0.35/0.40 on Harlem & Autechre & publish an incomplete test as I did for aotuv exp-bs1.

Be it Nero AAC or aotuv it seems to me that it's gonna be very hard to improve them in a signifiant way ... actually I have the same feeling after testing Nero 1.5.3 than I had when I tested aotuv exp-bs1 ... I feel in front of a wall. I feel like I am searching a pin in a haystack & honestly I don't like it.

Just woke up & I noticed I made several times a typo, when I speak of 1.5.1 vs. 1.5.3 it is indeed 1.3.3 vs 1.5.3 ... sorry. It would have been obvious if I would have published the results as a table ... maybe I should have.

Edit: Well here are the four more interesting logs:
(to be short Nero 1.5.3 is not transparent for sure at up to 0.40. Artefacts are obvious, annoying & instantly ABXable. But it is not new as I had the same result with 1.3.3 in my old listening test.)

On 65daysofstatic's "65 Doesn't Understand You" starting at ~8 sec, Itunes appear to fail more gracefully than Nero. Both are ABX'able at Nero's Q0.41 and Itune's 128 CVBR, and both were encoded at about the same bitrates (4.8 MB vs 4.9 MB). However, Nero's artifacts were significantly more annoying, enough that I noticed them while on listening to my shuffled playlist and started ABX'ing. I was also able to ABX Nero's Q0.50 too. Same with LAME V2, but not V0. My main concern here is that the artifacts are annoying, considering that other encoders are non-transparent as well.

I'm unsure of the etiquette here. Do I provide an ABX log or a clip of the sample?

It would be fine if you could provide a clip of the sample. This way the problem can be confirmed, and everybody who likes to can get an impression of the degree of personal annoyance for 'his' encoder and setting.

Sadly Nero AAC still has trouble with heavy smearing at 0.40 and sometimes 0.50.

Smearing on drums at the start, and then heavy high hats on the cymbals is introduced at 0:08 and throughout, due to smearing artifacts. This track seems to share the problem with the Linchpin sample.

Thanks.

The sample can be found here. (http://www.hydrogenaudio.org/forums/index.php?act=attach&type=post&id=5593)

The sample is also ABXable at -q 0.40, which shares the same problem with Linchpin and The Missing samples.

So here's what happens when I use the 1.5.3.0 update, I set it up to encode 17182 songs in fb23k using the following parameters:

-q 0.50 -ignorelength -if - -of %d

about as default as it can get.

Each time it gets to  the following point, the encode fails and each subsequent song fails too. Here's the error I get:

15728 out of 17182 tracks converted with major problems.

Source: "F:\FLAC_ARCHIVE\Attrition (2009) The Hand That Feeds - The Remixes\C90F670D_1803807.flac" / index: 4
  An error occurred while writing to file (The encoder has terminated prematurely with code 1 (0x00000001); please re-check parameters) : "C:\tmp\Attrition\(2009) The Hand That Feeds - The Remixes\01_04_Cosmetic C.m4a"

Working folder: C:\tmp\Attrition\(2009) The Hand That Feeds - The Remixes\


What's weird is that once it hits this FLAC file it dies on every subsequent one too. If I try and start the encode after this file I get the same error about 1000 files in on a different file. I can encode all these files fine with the 1.5.1.0 version and the 1.3.3.0 version, or any other codec for that matter. I checked the file integrities of all my FLAC files and they're okay too. If I encode this particular file individually it works fine as well.

The problem with all of this is, I'm not patient enough to sit around waiting for the encoder to start failing, if I feel like transcoding all my lossless files, I don't want to have to go back and hunt for when the encode fails as well. Any ideas? I saved the entire log (which is crazy huge) if it's needed.

I just noticed a change with dBpowerAMP encoding after upgrading to Nero 1.5.3.  Before, with all versions of Nero, iTunes would display Nero AAC along with the version in the "Encoded with" area of the song information.  This held true even with Nero 1.5.1.0.  Now, with 1.5.3, iTunes will display "Encoded with: dBpoweramp Release 13.2".  It only does this with some albums though.  This never happened until I started using 1.5.3.  It seems like 10 out of 500 albums will display that instead of Nero AAC 1.5.3.0.  I can go back, re-encode my source ALAC files with dBpowerAMP and Nero 1.5.3.0, and iTunes will display the appropriate information (ie Encoded with Nero AAC 1.5.3.0).

When I use nero 1.5.3 from the command line and look at the encoded MP4 files with a text editor, I see text like "cdec", "Nero AAC codec / 1.5.3.0", and "ndaudio 1.5.3.0 / -q my quality level". So probably not nero's fault.

Same here. Looks like foobar2000 is stripping the CDEC tag for some reason when tagging the file (but why does it do it with that version of the encoder and not with the previous ones?). I use a command-line encoder setting to get an m4a file, and the command line parameters are a standard "-q 0.5 -ignorelength -if - -of %d".

I also noticed that the files are slightly smaller than with version 1.3.3.0, with lower bitrates for the same quality settings. Nero seem to have removed the previous version--does anyone know where I could get it again?

So I have two FLAC files (they're FLAC files with cuesheets embedded) out of about 1500 that the Nero codec 1.5.3.0 fail on rather ungracefully.

I'm using Foobar2000 v1b6

I'm using the following string:  -q 0.50 -ignorelength -if - -of %d

Here's one of the errors I receive:

Code: [Select]
Source: "F:\FLAC_ARCHIVE\CoH (1999) Vox Tinnitus\36047604_16929.flac" / index: 2
  An error occurred while writing to file (The encoder has terminated prematurely with code 1 (0x00000001); please re-check parameters) : "C:\tmp\CoH\(1999) Vox Tinnitus\01_02_Silence Is.m4a"
Additional information:

Command line: "C:\audio\NeroAACCodec-1.5.1\win32\neroAacEnc.exe" -q 0.50 -ignorelength -if - -of "01_02_Silence Is.m4a"
Working folder: C:\tmp\CoH\(1999) Vox Tinnitus\

Here's the other one:
Code: [Select]
Source: "F:\FLAC_ARCHIVE\Attrition (2001) The Hand That Feeds - The Remixes\C90F670D_1803807.flac" / index: 4
  An error occurred while writing to file (The encoder has terminated prematurely with code 1 (0x00000001); please re-check parameters) : "C:\tmp\Attrition\(2001) The Hand That Feeds - The Remixes\1_04_Cosmetic C.m4a"
Additional information:
Encoder stream format: 44100Hz / 2ch / 16bps
Command line: "C:\audio\NeroAACCodec-1.5.1\win32\neroAacEnc.exe" -q 0.50 -ignorelength -if - -of "1_04_Cosmetic C.m4a"
Working folder: C:\tmp\Attrition\(2001) The Hand That Feeds - The Remixes\

so what it appears to be saying is that it's failing on index 2 (track 2) of this particular FLAC file. I can encode it in to FLAC, MP3, APE, OGG, whatever....
I only get the error on this index with the Nero AAC codec.

What's interesting is that once it fails on one index of the FLAC file, it fails on EVERY SUBSEQUENT ONE not only in the particular FLAC file but the rest of the files I'm trying to encode as well.

Since I can encode these files with any other encoder it's leading me to believe the problem is with the Nero AAC codec and not my FLAC files. I've verified their MD5 integrity, I'm sure they're valid.

In the interest of getting it fixed (and not piracy duh) if the Nero developers would like to have me PM them a link to each of my FLAC files so they may test
I will be happy to provide these files as-is. Lemme know if that's something you want.


UPDATE:

I just encoded these files with 1.3.3.0 and they worked fine as well.

Seems that there are at least 3 issues with 1.5.3.0 floating around:

1) SSE
2) Missing CDEC tags
3) Frozenspeed's failed FLAC conversions

That being so, I'm wondering whether another bugfix version is likely in the near future. I'd be a tiny bit annoyed to convert my whole FLAC collection and then find an updated Nero version the next day.

Bug fixes won't affect quality of the files produced.*  It would just allow the encoder to work smoother under specific conditions.  There weren't any quality fixes between 1.5.1 and 1.5.3, they only fixed that SSE bug.  A -q0.5 file produced with either encoder is the exact same quality and will have the exact same bitrates.

*Edit: unless there is a encoder quality bug and, so far, nothing has come up for Nero 1.5.3 regarding a poor quality encoder bug that fails with certain non-killer samples.

Seems that there are at least 3 issues with 1.5.3.0 floating around:

1) SSE


Already fixed in the update from 1.5.1.0 -> 1.5.3.0.

Quote
2) Missing CDEC tags


This seems to be caused by foobar's tag editing, not by the AAC encoder.

Quote
3) Frozenspeed's failed FLAC conversions


Frozenspeed provided a sample to reproduce this. We will likely update the encoder again once this is fixed.

Quote
That being so, I'm wondering whether another bugfix version is likely in the near future. I'd be a tiny bit annoyed to convert my whole FLAC collection and then find an updated Nero version the next day. 


With regards to quality you will not have to worry about this, we will not do any quality related updates until the next major release. You'll only have to wait for the next bugfix update if you encounter the same problem as Frozenspeed during your conversion process.

New problem:

5g Ipod Nano. Encoded a bunch of files from flac/ape to .m4a nero aac 1.5.3 at 0.5  quality

John Lennon's "Plastic Ono Band" will not sync. Itunes says that the files use a bitrate that is not supported.

Looking at it again, it's a sample rate problem. Apparently, somehow, it's not a 44hz file.

Hi all

from the changelog:
    - neroAacTag:
        - Support 3GPP tags


how to use that feature? There's no mention in the -help screen. I am hoping it can create tags recognizable by the PS3. (see [a href='index.php?showtopic=60156']here[/a])

Thank you

For gapless playback.

Post by: Alex B on 2010-02-18 16:13:19
Out of curiosity, what other methods for AAC/MP4 gapless playback exist?

For instance, what did Nero MP4 + fooobar use before this "iTunes" tag?

It would be safer if the info would be stored somewhere where a careless tag edit could not so easily destroy it. For example, the LAME Info Tag header in MP3 files isn't accessible in usual tag editors.

Until recently, I actually thought that sample accurate AAC/MP4 decoding was standardized, transparent, and automatic similarly like gapless Ogg Vorbis or Musepack decoding but apparently that is not the case.

EDIT

For instance, I often replace all tags in converted files by copying more complete tags from another set of files. If I use the "Tag Copy/Paste" feature in Mp3tag it removes the previous tags completely.

The NeroDigital chapter list, which is still written.
We just also write iTunSMPB now to increase compatibility with more software/hardware players. Removing it will not hurt as long as your player supports the chapter list.

Thanks, Alex B for asking this.  I am still a huge fan of Musepack (*ducking*) and Vorbis due to gapless playback being my most important requirement in a codec.

Nero is gapless on Apple's stuff, and foobar, but not Winamp or surprisingly even Rockbox (at least as of 1.3.3 Nero/Rockbox 3.3).  I asked Rockbox forums why it was gapless elsewhere and was told that there is gapless info written into the files, but that they did not know where, so they couldn't utilize that info for implementing gapless playback on Rockbox.

I haven't tried the newest Nero yet, but it looks like maybe things are improving there!

Funny thing regarding the CDEC tag: Using Nero with dBpoweramp writes the tag correctly. Then adding album art with MP3Tag (v2.45a) deletes the CDEC tag! I would guess that the fault lies on the MP3Tag side (so I will mention this in the forums over there), and yet this didn't happen with Nero 1.3.3.0....

Edit: my memory seems to have been playing up - just tried it with 1.3.3.0, and whoops - there goes the CDEC tag. So just ignore me!

Thank you Nero Devs  keep up the good work and keep improving your great encoder!

I have 3 questions to make:

1- Are you going to release a Mac version for your AAC encoder too? It is always nice to have it on all platforms.

2- Isn't there any x64 version of your encoder? If it may help to speed up the encoding i believe it should be made.

3- Is Nero as true vbr as Apple AAC TVBR? As far as i've seen it looks like even Q127 has a lot of fluctuations of bitrate,even big in some cases and it looks like speed of decoding is extremely fast. True VBR in fact has the lowest complexity of all LC-AAC modes. I'm a bit confused about all of this VBR/True VBR stuff,i've always been used to the traditional VBR of lame or Nero and i wonder if you are going to implement true vbr in the future too.

Thank you once again and keep up the good work!

Hello Nero devs!

First I'd like to thank you for this great encoder. I use mostly HE-AACV2 at 24kbps for my mobile phone, with impressing quality (of course far from transparency, but amazing nonetheless for such low bitrate).

I've noticed some glitches with HE-AACV1 content being played at my Nokia N85 (also on N95). It's high pitched squeaks that occur in some songs. Forcing V2 solves the problem, but for higher bitrates such 48 or 64k V1 gives better results. Please see more details in this post:

http://www.hydrogenaudio.org/forums/lofive...php/t78679.html (http://www.hydrogenaudio.org/forums/lofiversion/index.php/t78679.html)

Is this some kind of incompatibility with Nokia player, or maybe a bug? I've noticed this in v. 1.3.3.0 and the new one (1.5.1.X) gives the same results.

Thanks,
Rogerio

hey there. i'm actually new to the forum and i don't know if i'm supposed to post my question here tho i will since there are tons of double-posts and i'm a bit lost.

first off: i wanna use neroaac as my future encoder and i saw that it's the best encoder at about 160kbps which is perfectly fine with me. i used to encode with LAME at 192 cbr so far and i would now like to encode with neroaac at about 170 kbps VBR from now on. which is the appropriate quality setting for that? is it the default 0.5 or something more or even less cause the pdf coming along with the zip file of the encoder only explains certain values. 

secondly: is there any frontend-transcoder working perfectly with neroaac? cause using it as an external or various apps doesn't work quite well (as far as i've tested that is)

and last but not least: is there any program that features the constant bitrate viewing  of an aac track? winamp only shows the bitrate of the first soundframe and that's why i asked the first question first place 

thank you for your time

You should conduct your own proper listening tests in order to determine if that bit rate (and corresponding setting) is right for you.  There is no need for you to encode at -q.47 if you cannot ABX -q.35 or -q.40 from their source lossless files.

which is the right quality setting for about 170 then? is it 0.46-0.47 or is it 0.51-0.52 ? everything/one gives me totally different info. whom should i trust? like i said in the beginning; i want something (VBR ofc) at about 165-175 kbps. is there noone that can responsibly give me an answer to that? i mean neroaac sounds like a good encoder but it's too messy to understand! i would appreciate any assistance ...

It is not hard to understand.  As previously pointed out, vbr is just that: variable bitrate.  Why not try some different settings with your songs to determine what is right for you?  Why are you set in 170kbps?  Is it too much trouble to fire up foobar2000, encode some tracks at various settings, and see which one comes out right?

first: i'm stuck at 160-170 to save some space in my p.c. without losing quality

secondly: what i've said is 'cause i've tried both the console mode of the encoder and foobar2000 and each and every time i get completely different bitrates at various quality settings i've tested and that's why i'm confused. sorry if i did not mention that.

e.g. i tried -q 0.47 and i got a range of 150-179 and i tried -q 0.53 and got the same ranges (filesize is bigger at 0.53 ofc and i knew that would happen). but then i tested 0.47 on some different album and got a completely different range of bitrate values. i also reckon that album production differs from album to album but i don't think that this explains the major differences in bitrate ranges i'm getting.

No, it does explain the difference. Different music requires different bitrates for the same quality.

The main advantage is that the user is able to specify the quality level and conserve as much space as possible, but the inconvenience is that the final file size is quite unpredictable.

perishedinflames, why don't you use ABR at 170kbps if that is what you want? VBR will NEVER guarantee your desired bitrate.
Considere that ABR allows the bitrate to change throughout the song (unlike CBR) and give the more complex parts more and the less complex parts less bits, but the overall bitrate will always be as you specify.

This could happen on some songs because of the nature of HEv1 and HEv2.


Hello muaddib,

I don't know if I expressed myself correctly (sorry, english is not my language).
I'll try again

I meant that HEv1 presents lots of artifacts (squeaks) in about 30-50% of music encoded with it, in the 48-64k range. This seems only to appear when played with Nokia phones.

Forcing HEv2 in 48-64k range does solve the problem. But we are at a loss when encoding HEv2 in such "high" bitrates, aren't we?

Songs were converted with dbpoweramp, nokia compatibility.

If needed, I think I can digitize the output to show it, during the weekend. Please let me know.

Thanks!

This sounds like there is some problem with the decoder on that phone. Can you try a couple of different players to see if it really doesn't happen with other decoders? I suggest Winamp, iTunes (if you have it, or don't mind installing it), foobar2000.

Yes, I'll try other decoders, though I remember playing the HEv1 files with Media Player Classic in XP and not hearing the artifacts. Will confirm during the weekend.

I had a N95 8GB, my girlfriend has a regular N95, and now I own a N85, all of them struggle the same way with HEv1 CBR or ABR, with Nero AAC 1.3.3.0 or 1.5.1.X
The squeaks are quite noticeable and frequent, more like corruption.

I have tested this today. Under windows there are no artifacts. I have played the sample in my N85 and digitized the output, so it could be shown here.

As I said this has happened in 3 different Nokia phones, so I think this is a widespread "caracteristic"

Yes, -hev2 fixes it in my Nokias. The point is that for 48-64k range, v1 gives better results (sans artifact). No I havent abx it

No, no speaker. It was hooked directly to my desktop onboard sound input, levels adjusted by ear and captured with win sound recorder... No big worries with quality, but you get to the point.

IS AAC+ Best Lossy Codec or maybe OGG is better ?
Title: Nero AAC Codec Version 1.5.1.0 released
Post by: Zarggg on 2010-06-11 07:41:54
Neither. Both are perfectly viable codecs.

(Also, this question is off-topic for this thread.)

Also, AAC+ (a subset of AAC as a whole) is intended specifically for low-bitrate use and relies on 'making up' the audio at higher frequencies (dodgy wording; all lossy codecs must reconstruct audio, but especially so when using SBR, correct?). Vorbis, on the other hand, is designed for use at a wide range of bitrates.

There are various lossy codecs, and the "best" one is the one that your preferred software and hardwares supports, and that can be transparent to you at your preferred bitrate/filesize. There's no point asking other people; they don't have your situation or ears. Please have a read around the wiki and previous topics.

Does anyone have an Alpine car deck? I have an Alpine CDE 112Ri and supports MP3/WMA/AAC from usb together with iPod connection. I have no problem at all playing Apple AACs file,even true vbr, but it doesn't play Nero ones. There is silence but the car deck reads them as you see on display the running time. Some songs work others not, other times instead they work. Shouldn't AACs be all the same? I mean Nero makes compatible AACs now with .m4a extension and Apple tag system.

I have the opposite problem on my Pioneer, Nero creates files which play without problem, having tested probably a few 100, but on a random selection (maybe 1 in 5) the tags are not read properly by the head-unit (show up fine on everything else). AACs from the same source via Apple software work 100%.

Conclusion: 1) head-units by Pioneer and Alpine and probably all the rest are utter crap designed by retarded monkeys, and 2) Nero AAC still isn't creating AACs that are quite what they should be.

Suggest you do what I have settled on and use qtaacenc (http://tmkk.hp.infoseek.co.jp/qtaacenc/), works brilliantly and isn't slow.

thank you for your answer, i imagined it had something to do with these producers. They could do so much more instead of this crap (not to mention how many problems I encounter, Power IC turns off randomly, Error-01 with iPod sometimes), it shouldn't take long to add support via usb for wav (some head units do), flac at least and ntfs support. For conversion thanks, already know about qtaacenc and use that on Windows; i also have a MacBook Pro and use XLD there. So can't Nero team do anything for this right?

I'm having some trouble converting a lot of files to aac using foobar2000. I just updated neroaacenc.exe and when I started converting all my music files (to send to my iPod) and I noticed that after a bit, one of my cpu cores was "converting" the songs at an incredible fast speed. In the end, as expected, I got an error report for almost every single music file that it tried to convert. I also tried to convert all the files to mp3, but I didn't find any problem like this, so I believe the problem lies in the encoder.
After some more tries I noticed that there was one specific music file that was triggering this. If I try to convert only that file, I don't get any error at all. If I choose to convert some musics before that one and some after, I get those errors:

Song that triggers the problem:
Code: [Select]
Source: "C:\Users\Joao\Music\Dekaron\00-bgm-arcana.mp3"
  An error occurred while writing to file (The encoder has terminated prematurely with code 1 (0x00000001); please re-check parameters) : "C:\Users\Joao\Musicas Convertidas\-  - Arcana_ripped.m4a"
  Additional information:
  Encoder stream format: 44100Hz / 2ch / 32bps
  Command line: "C:\Users\Joao\encoders\neroAacEnc.exe" -q 0.50 -ignorelength -if - -of "temp-6D7D03B8F5F76B6B2257DA4DCC7CCC70.m4a"
  Working folder: C:\Users\Joao\Musicas Convertidas\


One of the songs after that one:
Code: [Select]
Conversion failed: The encoder has terminated prematurely with code 1 (0x00000001); please re-check parameters
Source: "C:\Users\Joao\Music\S4 League\Come On.mp3"
  An error occurred while writing to file (Unsupported format or corrupted file) : "C:\Users\Joao\Musicas Convertidas\-  - Arcana_ripped.m4a"

  Working folder: C:\Users\Joao\Musicas Convertidas\


I've tried to remove that song from the converting list, but it seems that there are some other songs triggering this problem.

I investigated a little bit more about my problem with Nero AAC and Alpine Car Deck and i got wrong about a few things. It never played Nero AAC files actually, or better yet it plays them (no unsupported message) but there's only silence with any setting i try to choose. But there are some songs, at least i found one of my collection which plays normally and i don't get what the problem might be since it uses the same bits of other encodes (q 1.00) but works fine. AAC support is assured but I don't trust Alpine when they say that. Anyway Nero Team could you please investigate on the problem for the next release? Don't tell me to use qtaacenc or stuff like that because i like the semplicity and speed (but it is also trasparent to my ears after ABX) of Nero instead of Apple's encoder. Please, i hope it to be fixed if it is somewhat related to Nero AAC files.

What do you have to substantiate your implication that the QT encoder is not transparent when the Nero one is?

Why do you consider Nero a) simpler or b) faster? I don't see that it's simpler, other than the requirement to have QT installed for qtaacenc, and it's not substantially faster.*
* On a Q6600 using all 4 cores via Foobar I see an approx 5:6 ratio in speed in Nero's favor - a difference for sure but not much of a factor in the decision to use either.

i haven't said that one is better than the other, I only said that to me, after my tests i find it better for my needs on Windows. It's simpler because i don't need to have installed anything to use it except the command line encoder lol and it's faster because on my machine it takes less to encode compared to any QT AAC encoding (QT 23-25x Nero 33-35x, it's not as fast as lame yet but that's another story). Anyway i'm not here to discuss about the one compared to the other, not to mention that they are both of very high quality, we all know that =) then it's up to anyone to use whatever they want. I only asked Nero team to investigate on the issue if it's related to Nero AAC somehow since some songs work while others not.

Oh, yes Apple AAC encoder is as fast as LAME. qtaacenc has slower speed because  has --high option at default  settings (higher quality, lower speed). iTunes has no this option.

1. Do you make conclusion looking at the result of one sample? Encoder can do better on one sample but worse on others. That's actually happens with 1.5.4. Overall there is no quality improvement. Read the entire topic.

2.
I haven't done a proper ABX test, but it's immediately clear (to me at least) that the new 1.5.1.0 encoder is MUCH better on this sample.

So you have made a conclusion basing on a single result without blind test.

There is no point doing a blind test I know I will fail completely having got 16/16 with the previous version. I know what artifact I heard with the old version, and it has gone with the new one.

Your previous post was, IMHO, a little dismissive of the Nero developers.

On some samples it got better, on some samples it got worse. Due to the big investigation that was invested in it, I believe that in average (among samples and listeners) it got just a bit better, but at the end it depends on what music you like to listen and if the changes are good for your ears or not.

Regarding SBR encoding, what if you first encode the core stream, than turn quantized signal back to time domain and feed analysis QMF filterbank (its LF part) with the same signal it operates in decoder. Do you think this can have any positive effect?

Umm...  A 16/16 would mean that you were able to effectively pick out which track was which during a blind ABX test.  In other words, that is an ABX test that you "passed."  Failing a test would be obtaining a much lower score and a higher probability that you were guessing.  The whole "I know what I know" argument really has no place unless it can be backed up.  What you think you remember hearing is not always accurate hence why downloading an older version of the Nero AAC encoder and testing it would be wise.  Conducting a quick listen comparing to what you think you remember and relying on a two year old thread (which discussed a spoken word sample) is not enough to backup any claims.  IgorC's post was also not dismissive of the Nero AAC developers.  They were simply pointing out changes that have been applied to the encoder affecting output quality.  Encoder updates do not always improve quality and many focus on stability issues.  Igor's post would have been dismisive had they said "Nero AAC hasn't been updated in 3 years for LC-AAC encoding because the Nero devs are lazy bums who can't code to save their lives."  Simply pointing out changes of a specific encoder over a period of time is not indicative of developer performance and they did not make an opinionated comment regarding that.
