This produces the envelope for the carrier to follow. Each frequency band measures the dynamics of the modulator. Think about it like a gate for the carrier.Ī modulators signal is split up into the frequency bands of the vocoder. The ModulatorĪ vocoder will analyze the dynamics of the modulator and use that signal as an envelope for the effect. This means that there is a pretty good amount of volume across the whole frequency spectrum. The CarrierĪ carrier signal is usually something that is harmonically rich. The modulator is used as an envelope source. The carrier is used to provide harmonic richness to the sound.
