No sound.

I was just trying to experiment with getUserMedia to record audio. It seems so painful to find anything out about how to do this on the web... Anyhow, I tried out your widgets but get a flatline in the visualizer even though it appears (if I look at the microphone input levels going up and down) that the mic is actually picking up audio. I'm using Chrome Version 24.0.1312.52, definitely have audio input enabled, on Windows 7.

Try using a Chrome Canary build (be sure to re-enable audio input). I think your build is too old.

I have the same issue with both Chrome stable and Canary (versions 26.0.1410.64 and 29.0.1509.3) on Windows.

No errors in the console. I noticed freqByteData array has only 0's even though doFrequencyAnalysis gets called.
