A phase vocoder UGen that makes a series of gaps in a spectrum. This is done by multiplying the spectrum with a kind of rectangle wave that goes from zero to nyquist. The high slope of the rectangle lets the input bins pass (quasi pass-band), the low slope filters them out (quasi stop-band).
- Value Params
- chain
the FFT'ed buffer
- numTeeth
the number of periods in the rectangle wave, where zero would mean the input signal is not affected, one means that there is exactly one period of the wave across the spectrum, hence one pass-band and one stop-band.
- phase
the phase offset of the rectangle wave, where 1.0 is one full period. This is like the offset into the wavetable holding the rectangle, so a value of 0.25 means we start 25% into the basic waveform, and after 0.75 periods the next full period (high slope) begins.
- width
the pulse width between 0.0 (infinitely small high slope, so all bins filtered out) to 0.5 (half period is high slope, half period is low slope) to 1.0 (maximally wide high slope, no bins filtered out).
