Vocoder
AudioChannel vocoder analyzing a modulator to shape a carrier signal.
Splits both modulator and carrier through parallel bandpass filter banks (4-32 bands). Envelope followers on the modulator bands control the amplitude of corresponding carrier bands, transferring the spectral shape.
Tips
- Use speech as modulator and a rich synth (saw wave) as carrier for classic robot voice.
