h1. "Beatbox beta":http://github.com/rfwatson/live-beatbox

!http://rfwatson.github.com/images/beatbox.png!

Experimental drum machine which uses vocalization to select synthetic drum hits which best match beat-boxed sound.

Currently uses a combination of MFCC, SpectralCentroid and ZeroCrossing measurements to analyze and match the timbre of the sounds.

In super-alpha-beta state! It may or may not work on your setup.

h2. Requirements

• "SuperCollider":http://supercollider.sourceforge.net

• Some sort of external microphone and audio interface. I use an Edirol FA101 when building this. I haven't got it working well with the Mac's internal sound

• OSX - unless you want to make the GUI stuff cross-platform.

h2. Keyboard shortcuts

• @F1@ Record mode
• @F2@ Preview recorded sound
• @F3@ Jamming mode
• @Space@ Start/stop sequencer
• @Return@ Add hit to seq (while playing)
• @Backsp.@ Remove hit (while playing)
• @Up/Down@ Select channel
• @Left/Rt@ Crossfader control

h2. TODO

• Add analysis of amplitude envelope, only uses timbral analysis at the moment which while quite good it needs amp.env. comparison to be really intuitive
• Add ability to scan and add samples via GUI, from any location
• Improve doc
• Lots more...
