hello!

i am very new to pd (only been with it for a couple weeks) and am trying to figure out how to take an audio signal being played through the soundcard by another application or by the OS and split it into three (or any number) of frequency ranges.

i want to use this to take an audio signal, split it into three ranges, and convert each into a sine wave that would play at the average frequency of its corresponding range, taking a new average very frequently. my friend did this in max/msp and i'm trying to replicate as an exercise and because it sounds amazing.

i'm only looking for help on the first part because i want to try to do the rest on my own. we'll see how that works out.

thanks for any help, leo

what OS are you on???? you're gonna need a third party solution for your audio routing

you said you wanna do the second part by yourself, but i'll point you in the direction of the [fiddle~] object

i'm on os x tiger, so i'm waiting for the jackosx update, which would let me mute the internal mic on my ibook and pick and choose audio sources. i also need to buy a device that would give me a linein jack.

as far as fiddle~ goes, i found out about it after i made that post last night and now have a rudimentary version of what i want up and running.

thanks, leo

• an alternative to jack
  
  your ibook doesn't have a line in as well as mic? you should be able to choose an input from the system preferences.

all the ibook has is a cheap (but very sensitive) microphone to the right of the monitor behind a pinhole. there's no way to turn off its input; it's obviously meant to be used for voice control of the operating system. hopefully, soundflower (i know that jack will, whenever it's released) will cut it out, because if i want to play music through this, the ultra sensitive microphone picks up on every barely audible ambient sound you can imagine and plays back the frequency. fiddle's amplitude filter is sorely inadequate.

i'm just going to have to buy an imic when i get some cash. and then a real microphone. and then...
