BeepMap generates sound based on an image. Imagine a vertical line scanning an image from left to right translating (mapping) colors and brightness to frequencies, tone and volume. There you have BeepMap. BeepMap is especially good at producing atmospheric and eerie sounds, particularly when given generous amounts of ping-pong delay and reverb. BeepMap, translates the red color into the amplitude of a sine wave on the left channel and green colors into a sine wave on the right channel. Yellow, a mixture of red and green will therefore sound equally on both channels. The frequency of each sine wave depends on its vertical position in the bitmap. Optionally, the blue component is used to define the frequency range per pixel.more
