Factual Questions

I want to distribute audio recordings of interviews over the internet. What is the easiest way to do this?

Shoutcast?

Realmedia files?

Mp3 files?

Any ideas? I just want to have a list of files people can click on and listen too.

Thanks.

Real Producer from Real.com should record the files to your hard disk in one of several formats.

mp3, 44.1kHz, 128kbps(or better), my $.02.
