Can't Convert wav extracted from Virtualdubmod


I extracted the audio of an avi video to wav format in virtualdubmod intending to convert it to mp3, however I am unable to convert though I’ve tried various programs. Based on what I’ve read here and other places the problem is likely that my computer refuses to decode the file. I’ve been searching for a couple days to solve this with no luck. Does anyone know what to do in this case?

Try this app.

Thanks! I’m very grateful.
