How do I turn audio into video (that is, show the waveforms in a video)?

Question

I have to create a video. Part of it involves "showing" a radio interview. Rather than just having a black screen and listening to the audio, I'd like to have a varying waveform on the screen and a caption.Is there any free or cheap tool I can use that will do this?---*If I ask a friend to do it, is there anything in the Adobe Creative Suite that can do the job?*

Answer 1

ADOBE AFTER EFFECTS. Does it best. Very easy.. Its actually one of the earliest plugs ins and has been there for years..

It will provide you a digital or analog version of the waveform.
