License?

Thanks for publishing this, it's exactly what I needed. Does it use the same license as opencore-amr (Apache)?

It's not working...

high,

Thanks for posting this. Unfortunately, I haven't been able to get it working in Chrome. It does not decode AMR files recorded in Android 3.x nor 4.x and I cannot initiate WAV file playback either. I've been digging through the code for a couple of days now. Everything runs smoothly and I can verify that sound files are being read. I just don't get any sound nor am I able to write files. Can you help me with this?

Thanks,

Jair-Rôhm
