Recording audio on a Mac..?

[Carl]

Is there any freeware program for OS X 10.4x that can record whatever is playing in the OS "Mac Audio" (streams, video, chat, etc).

Audacity only supports line in/mic, the closest thing I've found is Wiretap but it's shareware and I'd feel kind of stupid paying $20 for something that nearly any windows app can do.

I actually prefer Audio Hijack to Wiretap.  It captures the audio output of a single app rather than everything coming through th sound card.  Plus you can schedule recordings.

Sixteen bucks but well worth it.
