A perceptually meaningful audio visualizer #ArtTuesday #Music @medium @d_e_lu
Most audio visualizers don’t reveal details in the music they represent. Artist David Lu created Audioscope, a new type of visualizer, and made a video and soundtrack to demonstrate how some of these fine sonic details are made obvious.
Sound is made up of sine waves of varying frequencies. The visualizer turns the sine waves into circles (Technically: The y axis is the raw audio signal, and the x axis is the signal filtered such that every frequency is phase shifted by 90˚.)
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.
