Developer's Description

HOWL is a simple vocoder/synthesizer.

HOWL is a simple vocoder/synthesizer. It uses formants to simulate the human voice and a pitch-space keyboard to help you find interesting melodies.


Simple synthesizer (just a sawtooth wave nothing too complicated okay)

Simple vocoder (four parallel bandpass filters, a bit like the Klatt engine)

Audiobus support, so you can pipe your own audio through the vocoder and/or send the output to other software

Adjustable pitch-space keyboard

Cool FX (bitcrush, reverb, vibrato and tremolo)
