I have a problem with an audio file, it's a .wav. Our phone system records phone calls "for quality assurance purposes" and are reviewed (or in some cases, investigated) often.
We have a situation where we need to listen to one of these calls and we've downloaded it from the system. It's apx. 2MB in size, but when we try to play it, there is no sound. There are no error messages, and the slider moves across like it is playing the file.
We've tried converting it to mp3, but the 'process' meter goes in a negative direction and never converts the file.
Does anyone know of a good tool that can analyze this file or somehow extract audio out of it?
