Mapping Images to Audio @superkittens

MeoWorkshop discusses the process to map each pixel in an image to an audible frequency. To accomplish this, a collection of unique frequencies of each pixel is summed, resulting in some waveform.

In trying to reduce the influence of uniform sections, I decided to use the difference in intensity between neighbouring pixels to calculate the magnitude instead of using pixel intensities directly.

For a given block, the intensity of each pixel’s RGB channel is subtracted with the intensities of the previous pixel. The resulting delta R, G and B vectors are then used to calculate the Euclidean distance. This process iterates over all the pixels in the block with the final magnitude being the max difference found.

See and listen to the full process here.

 


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
