Subtle Math Turns Songs of Whales Into Kaleidoscopic Images
What do whale songs and wavelets have in common? Quite a bit, and the
wavelets have nothing to do with water.
Mark Fischer found a mathematical tool to translate the subtlety and
nuance of whale and dolphin sounds into these mandala-like images.
In a Northern California studio, Mark Fischer, an engineer by
training, uses wavelets a technique for processing digital signals
to transform the haunting calls of ocean mammals into movies that
visually represent the songs and still images that look like
electronic mandalas. (His art can be found at aguasonic.com.)
