Opus / How to determine whether Opus file is VBR or CBR
Last post by Pierre22 -
I have downloaded a few audio tracks (no copyright) from Youtube in Opus format (using youtube-dl), but I do not know whether these are VBR or CBR encoded files. Mediainfo does not seem to give that info, nor does VLC (or it is somewhere a parameter that I do not interpret correctly).

Using opusinfo I get the following output:

Processing file "ts1.opus"...
New logical stream (#1, serial: e43e9edd): type opus
Encoded with Lavf56.40.101
User comments section follows...
        LANGUAGE=eng
        DURATION=00:04:01.601000000
        encoder=Lavf56.40.101
Opus stream 1:
        Pre-skip: 312
        Playback gain: 0 dB
        Channels: 2
        Original sample rate: 48000Hz
        Packet duration:   20.0ms (max),   20.0ms (avg),   20.0ms (min)
        Page duration:   1000.0ms (max),  998.3ms (avg),  600.0ms (min)
        Total data length: 3702647 bytes (overhead: 0.822%)
        Playback length: 4m:01.593s
        Average bitrate: 122.6 kb/s, w/o overhead: 121.6 kb/s
Logical stream 1 ended

Is it the variable "page duration" that indicates that it is a VBR encoding ?
Or does the constant "packet duration" indicates that it is a CBR encoding ?

If these variables have nothing to do with VBR vs. CBR, do you have any suggestions (tool) to find out ?
Thanks.

Support - (fb2k) / cue file editing is not working
Last post by oldgoat -
FB 1.4 b15

If I load a cue file to the editor screen it looks fine. after 'OK' FB reads and appears to use it, but the album list doesn't then see the tracks, and if I open the cue editor again, the contents have been rewritten to all show the album name for each track name.
Removing the embedded cue file has no effect.

AAC / Re: AAC made with EAC/QAAC won't add to iTunes library
Last post by ThaCrip -
I don't use iTunes but did you try newest QAAC v2.67? ; it just came out about 5-6 days ago.

I suggest you use Foobar2000 with the Encoders Pack (i.e. https://www.foobar2000.org/encoderpack ) for general audio conversion as it converts FLAC to AAC/MP3/Opus etc nice and easily (takes roughly 30sec-1min to convert a album from FLAC) and since you already got iTunes installed it should have no trouble making Apple AAC files using Foobar2000 with that Encoder Pack installed. since I don't have iTunes (or the like) installed I just extracted the needed files out of the iTunes installer so Foobar2000 works with QAAC to make Apple AAC encoded AAC files through Foobar2000's interface and I don't have to install any of the iTunes junk. you can adjust your settings as I think to make a typical iTunes AAC with Foobar2000 you just switch to 'constrained VBR' (i.e. CVBR) and switch bit rate to I think 256kbps. but in general I suggest using 128kbps AAC (q64 TVBR (which is the 'variable bit rate' setting in Foobar2000 encoders options)) as it's a much more efficient use of storage space and still offers strong sound quality.

so basically... I think you can use EAC to make FLAC files and then convert those FLAC files with Foobar2000 to AAC at your preferred bit rate and see if that works. also, I am just going to assume EAC gives the FLAC files the proper tags as if they do, it should bring over the tag info to the AAC files you make with Foobar2000 and I would imagine this should make you good to go. but I do know you can get tag info to your FLAC files etc using Foobar2000 to.

General Audio / Re: Questions on "loudness wars" and/or bad CD engineering - doing a FLAClibrary
Last post by H_Allen -
Thanks to all for your thoughtful responses.  I will follow up on all links and suggestions. 
My concern is not so much that there is some way to recover the damage done, and I totally agree the artifacts are generally in the original CD media.  I just cannot believe there is any legitimate "mystery" over the reduction in music sales revenue given the overwhelming proportion of literally nauseating product being foisted on consumers.  My aim is really to establish some facts to use in educating oblivious listeners when the opportunity arises.  In a wine analogy, it's like producers have conned most consumers into buying nothing but Ripple.

PS. I listened to the 2014 "Lights Out" album by Ingrid Michaelson.  It is the "pumping" or "ducking" equivalent of The Killers' "wall of noise" technique.  :)

3rd Party Plugins - (fb2k) / foobar2000 controller PRO can't detect PC IP anymore
Last post by ksio89 -
Well, since some weeks ago, foobar2K controller PRO Android app can't find the IP from one of my PCs where foobar2000 is installed. Everything is set up correctly: HTTP Control 0.97.14-fb2kc component is installed, and I can access the foobar2000 interface on 127.0.0.1:8888 through the browser. I've set a local IP for my PC and added it to "Listen on" box on HTTP Control options, but the foobar2K Controller can't find the IP. I even port forwarded the port 8888 on both TCP/UDP protocols, and choosing the PC local/LAN IP. As UPnP is enabled on my router, I shouldn't even need to do this, but I did just in case.

Looks like it's the app for some reason has broken UPnP support and refuses to find the PC, because other PCs in my local network and file manager apps like Root Explorer (SMB server) can detect and connect to my PC just fine. I wiped the app cache and data, and started the connection wizard again, but it didn't work either. Does anyone have an idea on how to make the foobar2K Controller app find my PC, or is the app broken forever? Thanks in advance.

info:
foobar2000 version: v1.4 beta 15
OS: Windows 10 Home build 17134.48 (Version 1803)
