One of the more interesting use cases for the Raspberry Pi is exploiting its DSP capabilities in interesting ways. There’s a lot of horsepower inside the Raspberry Pi, more than enough to do some very interesting things with audio, all while being powered by a small wall wart adapter. [Pierre] over on the Pure Data mailing list has a proof-of-concept Read the rest

Sunday software sound hacks

[Ico Doornekamp] sent us his ultrasonic-entirely code based-thermin project in response to yesterdays Virtual theremin. By using the programming environment Pure Data, he is able to transform his laptop into a dual input device (while only using a single microphone) without modification. By being so open-ended theoretically anyone can have a theremin within a few moments of downloading, … Read the rest

There’s no schematic, but in the video it looks like an Arduino drives a bunch of solenoids through relays. The PC interface is run on Pure Data, an open source programming environment for audio, video, and graphic processing. Thanks [Jay].… Read the rest
