Record Audio From Any Mac OS X Application
MrFreak writes "Have you ever wanted to grab a sound from DVD Player or record a RealMedia stream to AIFF? It's previously been impossible to do this digitally, but the folks at Rogue Amoeba have released a piece of software called Audio Hijack that allows you to record audio from any OS X application. Additionally, it can apply live audio effects to any application, so you can add an equalizer to MAME or play Quake 3 with a live echo or flanger effect."
Because as the site says, it frees you from proprietary audio formats. So now, you can record a real stream or file into AIFF, convert to MP3, and take it on your ipod.
