Re: [sc-users] amplitude follower

[James Harkins <jamshark70@xxxxxxxxx>]

It doesn't make sense to process an audio signal at control rate. Hence, SoundIn does not support kr.

Use Amplitude.ar( SoundIn.ar( 0 ) ) to measure the amplitude. If the trigger needs to be control rate, convert the audio rate amplitude to control rate using A2K.kr(theAmplitude).

I will second Dan's posting earlier today* -- saying that something "doesn't work" without any other detail is usually not helpful for troubleshooting. It wastes *your* time, which I assume is valuable, because then whoever responds has to ask for details that could have been included in the first place. At the very least -- what was printed in the post window? If there was sound and the sound was wrong, describe it?

hi all,

im trying to build an amplitude follower that will watch the changing

amp of a SoundIn, return the amplitude, and send a trigger to

something else if amplitude is greater than a particular value. i have

been digging around in the list archives, and experimenting with a few

things, but im not coming up with what im looking for. the

Amplitude.kr( SoundIn.kr( 0 ) ) method seems to not work for me, for

whatever reason. if anyone has any ideas or input, i would really

appreciate it.
