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.

Features:

• 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)

HOWL is also open source (check out the code at https://github.com/dclelland/HOWL).
