Start with a continuous tone containing a rich set of frequencies - this is called the carrier tone.

This follows the volume of the signal, and converts it into a a 'volume control' signal for each band.

Pass each of these frequency bands through an envelope tracker.

Put the signal through a multi-band filter, getting some number of new signals, each covering a different frequency range.

Start with speech as an electronic signal (e.g.

Vocoders were originally invented as a way to transmit speech over low-capacity transmission media.
