This is a basic implementation of a vocoder for NTS-1 mk II and NTS-3 kaoss pad. Connect your voice source to the audio-in to play some robot voice.
The decay curve parameter of the envelope extracted from the modulator signal.
The gain of the audio input signal.
An 8-band vocoder implementation.
A sawtooth oscillator with a vocoder.
This script generates a signal that sweeps exponentially from 50 Hz to 10 kHz and back to 50 Hz, then saves it as a WAV file named exponential_sweep.wav.
This code will plot the frequency responses of the individual bandpass filters in this vocoder and the combined response.
