Howl: A formant synthesizer is on the app store now

Free and quite interesting sounding too. Might have to give this one a try.

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 banks of five cascading bandpass filters, a bit like the Klatt engine)
  • Adjustable pitch-space keyboard
  • Cool FX (bitcrush, reverb and vibrato)

HOWL is also open source (check out the code at https://github.com/dclelland/HOWL). Send me a pull request!
