SoundTap Pro for Mac

SoundTap lets you record nearly any audio that plays through a Mac OS X including streaming radio, VoIP calls and Instant Messaging conversations. Simply install this software, turn it on and then all sound played on or through the computer will be recorded as wav or mp3 files. All audio is 'tapped' by a virtual driver directly within the kernel so the process is perfect digital quality.

* Recording internet radio and other streaming audio.
