Soundflower is a Mac
OS X (10.2 and later) system extension that allows applications to pass
audio to other applications. Soundflower is easy to use, it simply
presents itself as an audio device, allowing any audio application to
send and receive audio with no other support needed. Soundflower is
free, open-source, and runs on Mac Intel and PPC computers.
Example 1: To send audio from iTunes to Max/MSP, open the System
Preferences and select Soundflower (2ch) as the device for sound output
inside the Sound panel. Then, inside Max/MSP's DSP Status Window, select
Core Soundflower (2ch) as the input device. All output of iTunes should
now be sent to Max/MSP's adc~ object.
