An example of sound-reactive graphics.
Aug 8th, 2007, 10:51pm  
Hey.
Is is possible for anyone to just put out a very basic example of some sound-reactive graphics. Examplewise, just a box that moves to the beat or some such.
Btw it would be nice if it could be used live.

1: DON'T DOUBLE POST

There is a link at the bottom of the forum index that shows recent posts to the board - so we know you're here - it just means the moderators have to remove your other posts, which doesn't inspire them to help you.

2: Very basic sound reactive graphics is either the FFT most sound libraries in Processing produce (look up libraries) or just a bar representing the volume.

Everyone that says "can you make some beat-detection stuff" to me usually goes - but isn't it really easy all you have to do is pick out the beat? No - and if you think it is - write the code yourself.

I've started a thread for Beat Detection resources. If you find anything new please post there, sharing is good.

there's one of the Minim library examples that does exactly this. and another that shows you how to get input from line-in rather than the file that the above uses.

http://code.compartmental.net/tools/minim/quickstart/

and lots of examples, with applets and source, here:

(try FFT/LogarithmicAverages/ and BeatDetect/ (not entirely convincing but probably good enough for jazz...))
