virtualdub audio help

[natty]

how comes when i encode a movie in virtualdub and play it the audio is all distorted

[kschang]

What kind of audio is it?

[natty]

I dont know what type audio is but here is a file info of movie from virtualdub

[kschang]

Well, there you go. It says it's MP3. (MPEG Layer-3)

How does the audio sound by itself? What if you demux the audio and play it back alone?

how do u demux audio and is this done with virtualdub or another program btw audio is fine b4 u encode but after its been encoded its terrible all distorted

You can do it with virtualdub (as well as a whole range of other programs).

Is the audio just distorted when playing back within virtualdub, or are you playing in a media player (such as windows media player) ?

You might try extracting the audio to a WAV:

Play the WAV and see if it is still garbled. If so, there might be a problem with the source file. If not, you should be able to specify this WAV as your audio source (by clicking on WAV Audio on the audio menu).
