hi, i made a GEM patch, and want to make it react to audio playing from an external cd player (plugged into pd via the adc~ object)

are there any patches or externals on the net that will convert my adc~ input into control data for my GEM patch?

if i want to get an analysis of the incoming signal in respect to frequencies and stuff, do i have to do fft analysis? are there any other options?

ok, so i'm showing that i don't know ANYTHING here...so if anyone has an ideas, let me know!

thanks

i haven't done very much in the area of adc~ analysis myself, but i have heard that miller puckette's fiddle~ and bonk~ externs seem to be fairly popular for this task. i guess fiddle detects pitch and bonk detects rhythms (more or less). here is paper on fiddle and bonk:

(the paper is pretty technical, you might find more practical information elsewhere).

another note--if you have the resources available, you'll probably find the best results if can use two computers, one for audio and one video, and send the information with netsend/netreceive (or better yet OSC, i find it much easier to use).

good luck.

zac, you legend! that's totally what i needed!!!
