If you're a Russian speaking audio developer, you'll enjoy this:
I wrote a short article about your audio lib on habrahabr.ru - (its a populat russian geeks site) to make it more known/recognizable and popular since I didn't ever heard about your lib previosly and I did find it eventually in google. Maybe thats cuz you developed android port not long ago. And I'm waiting for your next libs for imaging and so on.
I just want to thank you for your great work on superpowered lib for mobile devices! I coudn't even imagine you made so much work and spent so much time on it. This lib is incredible and its incredibly fast :)
