I wrote a UGen the other day that allows you to change the tick rate (or sample rate, if you like), of any UGen that you patch to it. After making a mouse-driven example to test it out, I created this example so that the change in the tick rate could be driven by the audio itself. Here, the current loudness (RMS amplitude, to be exact) of the audio being looped directly adjusts the playback speed. Louder parts result in a higher tick rate. What you get sounds like a really broken record player. Not only is it stuck looping the same four bars, but it sounds like the timing belt is having all sorts of issues. Check it out!
