|MSGEQ7 7-Band Audio Equalizer Breakout Board 90Deg (Arduino, Raspberry Pi)
Boards - Electronics
The MSGEQ7 Breakout Board divides the audio spectrum into seven bands, 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz, and 16kHz. Seven frequencies are peak detected and multiplexed to an output that provides an analog signal of the amplitude of each band. The board is supplied with regulated DC (3.3VDC or 5VDC). The multiplexor is controlled by a reset and a strobe, permitting multiplexor readout with only two pins.
