Pixel Bender audio visualization
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 blend mode, 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 b
