Cheers,
as i was one of the first to learn from robux4 about his plans to create a new tool called mpa2wav that will allow to put every mpa audio stream, even VBR, into very normal AVIs.
Its hosted on everwicked.com in the download section at http://download.everwicked.com/download.ph...a2wav-0.1.2.zip and will add a WAV header to MPEG audio, so that it can be loaded into and muxed in AVIs with Vdub.
Anybody care to test it and to post his results here ?

Hehe ..... my first mod here is a clueless nooB .. lol !
Steves program is for sure ( i know him ) a CLI ( Command Line Interface ) tool, there should be a readme coming with it explaining how it should be used.
It will hopefully find its way into Vdub sources one day ( if its proven to work of course ), but until then you have to use it on the .mpa ( .mp2 , .mp3 ) audio file to create a .wav file with the same content. Its basically the same file then, but with a new WAV header added to it so that Vdub can open it ( 'audio' 'WAV audio' ) and mux it into the AVI.
Any other volunteers ... or will you give it a try again Sill !

Actually mpa2wav is a crap tool. The creator should be killed !
Anyway the latest version can be found at http://mukoli.free.fr/mpa2wav/
It is reported to work on Linux 
It's a CLI program and if you just run it, it will tell you the command line to use
About the VDub integration, I didn't ask Avery about that. I was more interrested about knowing why the VBR would not be handled correctly when playing when there are dropped frames. I think it may come from a bad (inaccurate) muxing in VDub but I'm still discussing with Avery about it.
Otherwise it is a 3rd party tool so that you can use it for any purpose AND with VDub. |

No
I'm thinking about an ac3wav. All these tools combined could make Nandub useless. And VDub the only supported and hack-free program. |

robUx4,
I tried your tool with a VBR MP3(a la Lame@R3MIX). It doesn't work for me. Nandub still has the supreme pwer for me .

I might be wrong, but, so far, the problem with VBR mp3 lies here : http://www.virtualdub.org/virtualdub_news_old.html
And putting your mpX in a WAV container will, I'm afraid, not change anything. I used some time ago something called Riffmp3, the goal of which was to add a RIFF header to an mp3 file (so that it can be loaded by VDub). It worked very well, even with VBR mp3, but the problem where still the same (async movies).
So, I wonder if mpa2wav can change anything.

With files that has no dropped frames, yes it can. With drop frames no.
A solution may come from a different muxing technic (like time-stretching) that could improve the system. But of course AVI will NEVER be good for such files. (MCF can solve the pb  )
Without dropped frames, VDub+mpa2wav produces the same quality as Nandub. But using no AVI tricks |

robUx4,
i am not sure what the problem is. i tried it on a small clip of a movie and it gave badly off sync audio. I am about to try the whole movie and see if it was a cutting problem. Then I will know more about what is happening. |

OK
BTW, I did the same program for AC3 :
http://mukoli.free.fr/ac32wav/
It's working great when muxed with video. WAV playback alone is not (dunno why) |

Well, Steve. I am sorry to report that your util doesn't work for me. The resulting AVI has bad sync. 
EDIT: I was talking about your mpa2wav of course.
Also, I have finished a simple MPA file checker based on your code. I have no site myself so I have no where to put it ATM. It is called MPACheck and it goes through and lists all frames that are invalid then lists the stats of the file. In the next version I would like to add the option of removing the bad frames.
