Beatbox beta

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.

Requirements

  • 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.

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

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…
