TAL-Vocoder is a vintage vocoder emulation with 11 bands that emulates the sound of vocoders from the early 80’s.

Here’s a demo of Tal-Vocoder in action:

It includes analog modeled components in combination with digital algorithms such as the SFFT (Short-Time Fast Fourier Transform).

This vocoder does not make a direct convolution of the carrier and modulation signal as other digital vocoders maybe do. It includes an envelope follower for every of the eleven bands.

This vocoder is optimized for voice processing and includes some algorithms for consonants to make the voice more intelligible.

The carrier signal is a VCO (Voltage Controlled Oscillator) with a Pulse, Saw, Noise and SubOsc. But it’s also possible to use the left stereo input as carrier. This way every sound source can be used as carrier signal. This plug-in supports every sample rate.
