Here be a vocoder demo that I recorded LIVE yesterday—that's right, all the pitch processing was done live, and essentially improvised on a basic structure, which you can do at home (or in the millions of public shows there will be a demand for as soon as you get this vocoder) with a donation of $100!
The song itself is pretty quiet, and vocals come in about halfway through, so adjust your volume as needed. The sounds early on are me blowing into my computer microphone while altering the vocoder to make chords....
Also! The song is a kind of rough draft from a project I'm working on with Katie Shook, Sibyl O'Malley, DanRae Wilson and a host of other wonderful others for Erik Ehn's Soulographie project.
