Amazing. I’m not sure I noticed this app when it first came out, and now it’s on the bus. So, as I did miss it, here’s the app’s full description:
Voco is a touch-controlled phase vocoder for manipulating sampled sound.
The sound is mapped onto the screen, with time running left to right, and pitch up and down. By touching the screen the sound can be manipulated and played like an instrument.
Sounds can be sampled from the microphone, via Audiobus, or loaded from iTunes or AudioCopy.
Voco is priced at $4.99.
