Pixel Bender audio visualization

October 25th, 2009

This simple audio visualization is based on a combination of pixel shader effects (2D lookup table deformation with sine and cosine functions) and BitmapData effects (accumulation effect, additive blending, blur filter).

Instead of running a “real” audio analysis with SoundMixer.computeSpectrum, I just measured the sound’s intensity level with SoundChannel.leftPeak and SoundChannel.rightPeak.

The SWF file was compiled with Flex SDK 3.3 and weighs 3.985 bytes (PBJ data included).
