Store description excerpt

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