This Spectrum Audio Analyzer project is nothing other than amazing. It includes a Teensy microcontroller board that drives 2 displays simultaneously at a very high speed. It is capable of doing a frequency analysis of the Audio in realtime to create a Stereo spectrum analyzer of 69 Channels and drive768 leds at the same time.
Yep you understood me correctly! 69 channels in stereo…so that’s actually 138 frequency bins. On top of that, we will be displaying a stereo VU meter on the second display.…
