Audio recording; converting formats; saving.
Starting from software like "Audio Hijack Pro"and converting with "Max" or saving with Toast. There are other software programs out there. "Audio recorder" ;"fission"; "Disco". I also use the Belkin recorder for note taking and converting to mp3. "ispeakit" for converting text to mp3's.
And Cepstral voices for reading aloud.
Understanding formats for the conversions. Now with Apple and EMI using no DRM; things are really becoming exciting. itunes using lossless formats.
Podcast from "Technight owl" talks about audio formats and Apple and EMI; DRM free.
New on the market is an audio software called "WireTap studio" Looks like a great improvement in making audio recording as simple as possible. Looks like the consumer wins bigtime on this one. You can hear about is at Technight owl live.
