i made a silly patch, that let's you control the volume of an audio
signal using [colorRGB], just to illustrate, that audio can be
processed on gpu by using gem and puredata. i'd be interested, if
someone has a more meaningful application using this approach. people
talked about doing convolution on gpu. what does it need to actually do
