 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.
