An audio player/encoder for CDs, MP3s and streaming-network audio has been updated.
3.0.1 makes it possible to listen to an mp3PRO file by drag-&-dropping it onto a control window or double clicking it in the Finder. There's also more-reliable system-input recording and broadcasting under Mac OS 9, as well as other enhancements, performance tweaks, and bug fixes.
Audion 3.0.1 is a free update for registered users. Otherwise it costs $29.95.
