Gnaural

Works great! Sometimes can't handle too many channels at once, though error catching in this case is very clean to prevent outright crashing. Would love to see more samples. Migrate some of those samples to the desktop version also!

The best freeware binarual beat program for os x at the moment!

I discovered a very cool companion to Gnaural - it's a looped wav/mp3 audio file of rain on a tin roof, and Gnaural loops it without cutting out. I find it really good to work to. Simply add a new 'voice' in Gnaural and choose this file (after downloading it). Here is a link to the audio file: http://www.freesound.org/people/digifishmusic/sounds/66472/
