Rogue Amoeba has released a new preview version of Audio Hijack Pro. This update fixes several bugs on Mac OS X 10.5 (Leopard) as well as AAC recording issues caused by QuickTime 7.3 on Mac OS X 10.4 (Tiger).
On Leopard, they're still working to finish the "Instant Hijack" functionality which enables the capture of audio from already-running applications. On Tiger, however, Audio Hijack Pro 2.8 Preview 2 is feature complete with plenty of updates and new features over 2.7.3.
The Audio Hijack Pro 2.8 final release, with Instant Hijack working on both Tiger and Leopard is expected to be released in the near future, but Preview 2 is now recommended for all users on OS X 10.4.0 through 10.5.1.
