I'm actually working on a project right now for an in-browser guitar amp simulator and the ability to record whatever you've played. Planning on doing a pretty in-depth writeup when it's done.

Very cool .. I am also a guitar fan .. did you see this site: http://www.soundslice.com .. they've done an amazing job.

Yeah, agreed. Super impressive. On that same token, you should check out http://getinstinct.com/ if you haven't seen it. Those guys are doing some really cool stuff.

Crazy .. Love it!

Looking forward to it. I'm sure that every guitar-playing programmer has been closely following all the new web audio APIs.

Didn't you write the Recorder.js? I was able to implement it with ease for what we're doing. It has a few too many quirks to use in production but it's mostly there. Have you encountered a crash when unplugging the headphones?

I'm the original author of Recorder.js... not sure why unplugging the headphones would cause a crash. It may be an underlying bug in the Web Audio API. Feel free to file an issue, though!

No, I didn't .. But I heard it has some glitches here and there.
