PItchshifter and low pass filter with pretty UI for HTML5 and MozAudio.
Voron is a pitchshifter + lowpass filter realtime audio effect. Its user interface is rendered on an HTML5 Canvas and realtime DSP uses the new Mozilla Audio API.
Altough the UI is rendered on Firefox 3.5+, Firefox 4 is needed for audio support.
Voron is built on top of KievII (UI rendering and pitch-shifting), dsp.js (FFT) and AudioData (Low Pass Filter and audio buffering).
*** INSTRUCTIONS ***
Turn on the pitchshifter and/or the low pass filter with their ON/OFF buttons to hear the effects. Demo starts "clean" (aka no effect applied).
Discrete button switches from semitones shifting (ON) to cents shifting (OFF) and viceversa.
