Have you ever listened to some interesting internet audio (perhaps a conference recording, or a sermon, or a radio show) and wished you could record it, but couldn't because the player's "save" feature was disabled? What if you had something like a Tivo™ for internet audio? It does exist, in ReplayRadio.
Replay Radio is a great little (and inexpensive) tool that can record (and save to mp3) any audio program, and while it can record anything you open, better still it can be set to open things on a scheduled basis, and even has a frequently updated list of thousands of existing shows and "stations" (again, using the term liberally since some are not radio stations but sites that archive daily broadcasts).
If you need the tool to record some favorite site's daily show, you can email the vendor and they'll try to create a link you can use that will automatically get the current day's show. Sweet. Also, if you don't want to hear the show playing while it's recording, there is an option to mute while recording (as well as to optionally remove dead air, choose the quality of compression to use, and for IPod users, it can write directlly to iTunes.)
All this for just $30. There is a free 7-day demo. See the screenshot tour, FAQs, reviews, and other info offered. It may seem too good to be true. So far my experience has been great. Check it out
