A solution for the VBR MP3 mis-sync problem?

[kschang]

Excerpt from the DSFP codec pack

(Extra Info)
Q:Rendering MP3 files is already possible with the standard MPEG-I Stream Splitter, why add an extra one?
A:The standard MPEG-I Stream Splitter, and the new MPA Splitter from Gabest, report incorrect VBR (Variable Bit Rate) MP3 file duration. The MPEG-I Stream Splitter also fails to recognise some MP3 files with non-MP3 data such as ID3 tags as proper MP3 files, hence failing to open them altogether. This extra MP3 Parser Filter fixes these issues.

The file I got is a MP3Parse.ax exactly 100KB in size.

and ?

I don't know, I haven't tried it yet, as I don't have any AVI that has VBR MP3 soundtrack.

[celtic_druid]

Can't see how it would make any difference. It is talking about regular mp3 files. With an avi file it would be avi splitter-->mp3 decoder-->sound renderer

For mp3 and other audio files I would suggest foobar2k anyway or some other more dedicated audio player like winamp or even itunes.

and reguarding video, i'd advise against using vbr at any cost anyhow......or if you do, to just remux it with wav instead of vbr mp3.....particularly if your intending to reencode it....for playback though, just do like celtic druid says and use a program more specifically tailored to audio playback.....

[celtic_druid]

I would definatly recommend VBR over CBR (for both movies and music). Much better quality. Just ditch avi and use a container that can properly handle it. That said, I never had any problems using VBR audio in avi.

[guns1inger]

I don't have any problems playing them back, however converting them to anything requires the intermediate step of saving them as something more stable - prefereably uncompressed wav.

[celtic_druid]

If they play fine then they can be converted fine. The very fact that you can convert to pcm wav proves it.

[guns1inger]

Problem is, I have to go through this intermediate step because most encoders won't read them correctly. Some crash outright, some just have sync issues. Even audio software such as Sound Forge doesn't like them. So it's not that it cant be done, just that it takes more effort than it should. (That's without getting into the whole MP3 is an evil form of compression, period, conversation )

[celtic_druid]

avisource("whatever.avi")

That would probably solve your problems. That way AVISynth decodes to PCM on the fly as you convert.

[guns1inger]

Been there, done that. CCE spits the dummay and crashes out.

[celtic_druid]

Well I wouldn't recommend CCE for encoding audio anyway. Best limited to just video.

[guns1inger]

I don't - I encode everything AC3 through Vegas/Sound Forge - but unless I put a KillAudio, even unticking audio encoding in CCE causes a crash.
