Doing some live processing of sleigh bells in Pure Data to create an “Interactive Holiday Noise Music System.”
Since it’s mid-December, let’s make some holiday music. If you’re sick of the standard cloying Muzak fare, though, you can make your own feedback delay sample-crushing interactive music system in Pure Data in an afternoon.
The main point here is getting a “trigger” from audio input crossing a loudness threshold. Once we have that trigger, we can use it to make changes in live-processing of a sound and trigger other sounds too. This is a simple idea, but its effectiveness is going to depend on what these changes are and how we play with the system.
