I just released the audio library irrKlang
in version 1.1.3. It now should work faster on slow Mac OS X hardware and have very low latency even on some linux versions with very strange ALSA configurations. Additionally, I added the possibility to record audio in more than one channel, some example for VisualBasic.NET and several bug fixes.
The best release of irrKlang so far, but the latest usually is the best, right? :)
