We are releasing video tutorials soon. Right now we are focusing on stability and performance.
The only tutorial right now is the one that comes with AudioStellar when you first open it, have you tried it ?
Creating a new sound map is pretty easy. Just click File -> New and then choose a folder where your audio clips are (we are supporting MP3 and WAV at the moment). Then click Run and that's it !
Keep in mind that your audio clips should be no longer than 3 seconds for best results.
Let us know how it goes.
