The audio signal analysis module which is designed based on MSGEQ7 graphic equalizer that divides the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. The seven frequencies are peak detected and multiplexed to the output to provide a DC representation of the amplitude of each band. No external components are needed to select the filter responses.

This module can be used to create sound visualizers, detect patterns in music or add sound activation to your microcontroller.



  • Detect patterns in music - make a robot dance!
  • Process the values read, then display on LEDs as a soothing visualization which changes with the music.
  • Pimp the interior lighting in your car so it pumps to the beat and twinkles to the high hats. 
  • Create / listen for fingerprints in certain sounds - voice analysis.
