iTunes 10.7.0.21, CoreAudioToolbox.dll 7.9.8.1. Waiting for some expert to tell what's new.

Pink Floyd - The Dark Side of The Moon -V63 with 7.9.7.9 = 43.2MB, avg. bitrate 139 Kbps / -V63 with 7.9.8.1 = 42.6MB, avg. bitrate 137 Kbps

Pink Floyd - Wish You Were Here -V63 with 7.9.7.9 = 43.2MB, avg. bitrate 135 Kbps / -V63 with 7.9.8.1 = 41.7MB, avg. bitrate 130 Kbps

1406 -V63 songs + covers = 7.9.7.9 5.48GB / 7.9.8.1 5.36GB

I wanted to try to compare ALAC but the command -A doesn't work anymore:

Manual
Code: [Select]
qaac.exe -A "03. Pigs (Three Different Ones).wav"
qaac 1.40, CoreAudioToolbox 7.9.8.1

According to Apple, today's update was only incremental as it "just" added support for iOS 6 and iDevices that support said OS.  The big update, which isn't coming until October, may or may not upgrade the encoder that they use.  So I too am curious to see why things are a little different with this version of iTunes.

Right after I've reconverted everything I was thinking about iTunes 11, and maybe do it all over again, well... 20mins for ~1400 songs is not that bad.

I don't even think we needed a 10.7 version, I've been using iOS 6 since the first day of the beta and it was perfectly functional with iTunes 10.6, of course they have their reasons.

Let's wait for a reply from nu774 and see what's new on this version.

Released qaac 1.41 now.

There was a format change of ALAC magic cookie on the new CoreAudioToolbox (7.9.8.1).
New version returns the same format as the open sourced ALAC encoder, which is documented in ALACMagicCookieDescription.txt.
Probably this update was done to make them consistent.

qaac 1.41 takes care of both old and new format.

Thank you for the update.

Did anything change in terms of quality for AAC? I'm asking because the avg. bitrate for True VBR is lower and even the size is.

I confirmed resulting bitstream (and size) is different from 7.9.7.9, but I don't know what has actually changed (quality, bug-fix, etc).

I reencoded an album earlier encoded with CoreAudio 7.9.7.9 and the bitrate of newer CoreAudio is slightly lower.
Also I have made a spectral views of encoded audio short part, they are slightly different. Any conclusion which snapshot could be better?

7.9.7.9:

I don't think much can be said other than the results that were found conducting that test.  It might be all for not though since iTunes 11 is about a month away from being released.  Even then, that might not change anything with the encoder that Apple is implementing.  I have my reservations about upgrading to iTunes since it appears they are getting rid of the list view of an entire library but that is a different discussion.

If I understand good then audio data is related to apple's encoding library not to qaac.
Although I think there's little difference from previous version (compare bitrates and spectral graphs between versions)

Core Audio Toolbox was changed between those 2 versions, so what are you implying that I'm doing wrong here?

Well, like you said it was wrong, two versions of qaac don't change/mean anything for the decoder but now you've changed the reply and of course it makes the difference, the DLL from iTunes/QuickTime was different.

Just for the record:
Underlined is your assumption of what I was talking about (I have no idea why you or how you would assume that... because it's obviously very very very wrong)
Bolded is untrue.

Post by: eahm on 2012-09-14 17:32:57
neothe0ne, my last reply to this discussion.

I was just telling you that the DLL (CoreAudioToolbox.dll) is what matters for the encoding of AAC with QAAC, based on what you said here: "TVBR 91 appears to have no difference between qaac 1.39 and 1.41."

Also yes, you didn't change your reply, you changed your statement, correcting what you said before and saying: "Core Audio Toolbox was changed between those 2 versions". Of course the quality was going to be different, not because of QAAC though.


And talking about the topic again, it's funny higher encoding result in slightly smaller files, I just encoded at -V36 for a project and the files with 7.9.8.1 are bigger, Apple may have improved the quality at lower bitrates?

Title: New iTunes, new CoreAudioToolbox.dll
Post by: eahm on 2012-09-14 20:57:55
IgorC, I can try but I promise you right now I will not hear anything different. AAC is so good I don't even notice anything from -V54 to Lossless, these little changes they are doing now are not for us I'm sure but for some kind of encoder optimization.

Post by: Mix3dmessagez on 2012-09-19 23:01:22
I don't know if this means anything, but I converted an album back in june *using sound forge izotope to downsample and quicktime pro to encode*

I use tvbr, and granted there's a new itunes update and version of sound forge izotope since then *but not a new qt update*, I rencoded the album again with the same process and the bitrate between the two are dramatically different.

Here's an example

Song
Before 96kbps After 89

Song 2
Before 106 After 100

Song 3

Before 117 After 101

Song 4
Before 145 After 147


It's perplexing really, there's no consistency to the difference in bitrates between the 2 different encodes, the settings are exactly the same, and wondering possibly if it were an error I deleted the new encode and re-encoded all over gain twice, and the results are exactly the same. Using replaygain, the peaks are different too, quicktime uses core audio I believe, but I have no idea if it's that or the soundforge update *which updates the izotope converter too*.

If any experts can chime in I'd love to hear some theories.

List view will still be there, slightly different but it's still there.

Post by: Mix3dmessagez on 2012-09-20 03:25:56
I've went back and re-encoded other albums.

Allot show significantly lower bitrates on average than before.

What this tells me is the tweaks on coreaudio must've directly effected quicktime too, because it hasn't been updated in months but I'm already seeing a difference in bitrates.

Stuff that will be 139 will become 127, 130 will become 114, etc...

Some songs will show an increase in bitrate by like 4, but the drastic difference is in the bitrate drop.

I've used quicktime for a few years and this is the most drastic change in bitrate I've seen.

An album that was 56.3mb before now became 53mb.

Now, these albums I'm comparing are my personal needledrops and as I've mentioned before sound forge has been updated also *I downsample with izotope*, however in my experience downsampling in the past after the update while the peaks do change in the files the bitrates stay virtually the same. So I think this is all coreaudio at work...

I would love to hear an enthusiast chime in.

Mix3dmessagez, did you by chance read the first post? I've reconverted ~1400 songs, albums don't necessarily get smaller, some get bigger. For sure it's better, Apple likes to improve its components. Let's move on more technical details/issues.

Yes I have, I was just reporting from my personal findings quicktime itself has been effected by the coreaudio update, and not just the encoder in itunes.

Thanks for the info.

Can Apple (or even qaac) convert to HEv2? Is it possible with a specific command line or it's automatic below certain bitrates?

If it is available, you can probably use "afconvert -d aacp" or something in Mac OS X. I don't have Mac or iOS devices, so I'm not familiar with Apple products at all.
As for qaac, NO (same as iTunes for Windows).

your screenshot is very interesting.  for me, the bottom field - "original file name" - has a value of "CoreAudioToolbox.dll".  according to your screenshot, you're looking at a file that was originally named "CoreAudioResources".

are you sure you're looking at the properties of the file that QAAC is actually using?

qaac show 7.9.8.5, but file version is 7.9.8.4 and I have download itunes from Apple – iTunes site again x86 and x64 versions and the file version is 7.9.8.4.

I have extracted the AppleApplicationSupport.msi file.

No. New one is 7.9.8.5, File and Product version: http://imgur.com/QSb0GfX (http://imgur.com/QSb0GfX)

update:
I've extracted and renamed the QTFiles manually and everything works perfectly with qaac 2.33.

You have the wrong iTunes setup.

Check the version of iTunesSetup.msi (or iTunes64Setup.msi). The files in the new one are not even renamed like you see them there. They all have AppleApplicationSupport_ before the name.

my itunes version is 11.1.4.62 and AppleApplicationSupport_ before the name is if you extract with 7-zip.

if you extract with command line you don't have "AppleApplicationSupport" before the name.

But I have extract with 7-zip and without and the versions still the same 7.9.8.4.

here is my itunes version download again 2 minutes ago.

They just don't properly update version resources for every locale, so number shown in the windows explorer property should be inconsistent among various locales.

No. The CoreAudioToolbox.dll is internationalized, and contains multiple resource, each of which stands for USA, Portugal, etc...
The problem is that, version number contained in the resource for Portugal can be different from the one for USA.
Windows will pick up the one for your country /language settings. So, on different country, file version for the same binary can be shown different.
This has been a known issue, and qaac has been always using the one for en-US to avoid this inconsistency.

Thanks for your explanation.

well justifies why the same file shows a different number according to the location

but its very strange for me the version is 7.9.8.4 and for who live in USA the same file is 7.9.8.5

I think this version problem is neglible since CoreAudioToolbox seems only update the version number but not touched the encoder part in any way.

Hello,

I found that your latest (v. 4) makeportable.cmd script works as intended if I add ^^ before ! in 7z lines. Is it my environment (cmd in W7 64) that creates this particular behaviour?

Could you try instead adding the following?
Code: [Select]
setlocal disabledelayedexpansion

I guess you have enabled delayed expansion on registry setting or something, in which case exclamation mark will become another quote character that needs to be escaped as you say.
However, I'm afraid your solution should not work when it is disabled (and it is disabled by default).
If that fixes your issue, I can update makeportable.

You can check VideoHelp.com, as they post changelog.
http://www.videohelp.com/tools/iTunes (http://www.videohelp.com/tools/iTunes)

I don't actually ever use iTunes nor have the need to visit their site.
I'm sure their website must have a changelog somewhere.

But VideoHelp lists this short changelog for the most recent update to iTunes:
Quote
11.3.1
Addresses a problem where subscribed podcasts may stop updating with new  episodes and resolves an issue where Itunes may become unresponsive  while browsing your podcasts in a list.


Although not relevant to our needs for QAAC, iTunes isn't built solely for our needs for QAAC.

My guess is it's set to auto-update, but the only thing that changes is comments or nits which don't effect the output of the compile.

Just to clarify for myself, is it correct that the AAC encoder hasn't changed since CoreAudioToolbox.dll 7.9.8.1?
Title: New iTunes, new CoreAudioToolbox.dll
Post by: Aleron Ives on 2015-04-14 05:27:29
That sounds about right. I started using qaac at CAT 7.9.8.3 and have been following this thread since then, and Apple hasn't made any known improvements in the interim, and most "new" versions produce bit-perfect matches to the older ones. It seems Apple increments the CAT version number arbitrarily when other parts of QuickTime/iTunes change, but they've stopped developing their AAC encoding engine.
Title: New iTunes, new CoreAudioToolbox.dll
Post by: audiophool on 2015-04-14 22:52:00
^^^ Even if it's true that there haven't been improvements to the encoder's compression efficiency for some time, isn't is still desirable to deploy updates? Maybe they're fixing security flaws, or maybe they improve the runtime of some routines?
Title: New iTunes, new CoreAudioToolbox.dll
Post by: Aleron Ives on 2015-04-15 02:00:48
For those of us who only extract the necessary CAT DLLs to make qaac run and don't use QuickTime or iTunes, the updates are totally useless as far as I can see.

Confirmed, sorry iTunes was downloaded from CodecPack.co thinking it was the official direct link but I guess Apple uses more links, this one was named only iTunes64setup.exe (one 64 not two) and makeportable didn't extract QTFiles64 even if the iTunes setup file is the same.

I re-checked and indeed it was 7.10.8.0. Don't know what was wrong the 1st time. Sorry for the noise.

It's funny actually few times it did it for me and other users as well, we had to check 3-4 times to get the right version, not sure why. I check the DLL directly now.

Anyone check to see if the encoder has actually been updated?

Okay, took a minute to answer my own question

Encoded "40 Years: A Charlie Brown Christmas" using QAAC at q109 TVBR

Total size

7.10.7.0:  83.1MB

7.10.8.0:  82.6MB

If anything, it appears slightly more efficient.

Last one, I've been using FLAC exclusively from years ago and when I occasionally use lossy I go MP3 (LAME) or AAC (FhG with Winamp DLLs) because of its speed.

OT: I bought a Mac in December and it's funny how much better iTunes is on Windows.
