<![CDATA[Detecting audio volume level on Pure Data for GEM visuals.]]>Hello! First forum post, dunno if I'm doing it right, but I think this is where I post.

I was wondering if I could have pd detect audio levels of an audio and use that for intensity of an object motion on GEM. I want to do a visualizer for music but I didn't use pd but I still would like GEM's unique imagery. Please let me know if this is possible.

(xtra info: I'm going to export several isolated sections [drums, synths, bass] all into audio files and play them back on pd all at once, with each audio file having a visual shape attached to it with an assigned motion based on how loud the audio is.)

A great resource for working with GEM and Pd.
