A project log for (Funny) Audio spectrum by colors

An Internet Radio receiver based on ESP32 (D1 Mini), a DAC and two 12 LEDs rings showing "real time" audio spectrum by colors.

I added real time FFT i.e. now all the audio samples contribute to the colors at the same speed (22.050 Hz - stereo)  of the music.

I added also music and light start and stop time in the web page (TODO change the config web page picture)
