Repairing Audio in a AVI file

[no_pulse]

Is there a way to repair the audio in an AVI file? It seems that the audio portion of the AVI is corrupt. Any viewer I try to play the file in, it crashes the program.

I found out it was the audio... I tried using TMPGEnc to convert the AVI into an MPG and thats when I discovered that it didn't convert the audio over.

Is there a way to fix the audio in the AVI?

Any help would be greatly appreciated

Even when I open the AVI up in Goldwave, the program crashes lol..
Guess I'm SOL then eh?

redo the audio and mux it in with virtualdub to the old avi.

Load the movie into VirtualDub and either try to save to whole audio-track by using the save to WAV function and then try to convert the saved audio-file with different audio editors. I have found that the program MPEGSuite is very forgiving with respect to errors in MPEG-Audio.

In the case you are not successful then try to find the faulty spot within the movie, as long as its only one or only a few faulty spots. If you have found the corresponding frame-ranges then save the those parts of the movie where the audio-track is fine, then extract their corresponding audio-tracks, load the first part in an audio editor like goldwave, add the exact amount of silence of the next fault piece, then add the next intact audio-part etc. Finally you should have produced an audio track in the audio editor with the same length as the whole movie, save it as PCM-WAV file. After that add this audio-PCM-WAV-file within VirtualDub as audiotrack and finally save the movie again using the full processing option for audio (with the WAV-file as audio source instead of the AVI-track an recompress the audio track using the appropriate compressor settings.

Is there a way to change how big the projected file size will be in VirtualDub? I mean a 100mb file expands to like 7gigs lol... seems a bit much... any way to get that file size down?

iz never used virtualdub before

VirtualDub is a video-editor. If you only use it to cut a film with the video and the audio set to direct stream copy, then the size of all piece of the film you produce is exactly the same like the original movie of course.
If you reencode the audio or the video then the size of the reencoded parts depends on your encoder settings. So 80 minutes PCM-WAV is 700MB if the format is 44100 Hz stereo. 80 minutes MP3 stereo 128kBit will be about 60 MB.

VirtualDub does not have the ability to set a target file size.

I tried the method of just saving the .wav to file and then tried to re-encode it into the the video and still the video crashes when i tried to play the video...

something tells me the audio is FUBAR big time.... damn

If you were able to produce a WAV-file, you first have to load it into an audio-editor like goldwave or in case the audio-editor crashes on the attempt to load this extracted WAV-file (because this WAV-file still contains the audio in the orginial compression format like within the original movie) then try to use the conversion program "MPEGsuite" (you can find it easily via google, it is freeware) for a conversion into a real PCM-WAV-file. As the content most likely is MPEG-audio you will have to rename the extracted audio from "xxx.wav" to "xxx.mp3". To be able to change the file-extensions you will have to set the appropriate setting in the file-folder options of the Windows Explorer as "not to hide known file extensions" only then the filename extensions show up in the folder listings of the Windows Explorer along with the filename.

If the audio file can be fully loaded into an audio editor, then as I already mentioned you have to save it as PCM-WAV-file. If you have done all this and the movie still causes a crash of the player then the video-track seems to be faulty.
