Recoded Sound Files on Internet

A sound file. I'm not I'm grasping what you're asking. Are you?

Seriously, it depends on the format you recorded it in. WMF, MP3, etc.

Audience tapes (AUD), in contrast, were made by a listener who carried recording equipment into the venue and held a microphone up in the air. Sometimes this was tolerated or even encouraged by the band and promoters, but sometimes it had to be done secretly. Sound quality therefore varies tremendously.

Maybe podcast.
