|MSGEQ7 Dual Channel Stereo 7-Band Audio Equalizer Board (Arduino, Raspberry Pi)
Boards - Electronics
The MSGEQ7 Dual Channel 7 Band Audio Analyzer divides the audio spectrum into seven bands, 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz, and 16kHz. Seven frequencies per channel are peak detected and multiplexed to two 0 to 5vdc outputs that provide analog signals of the amplitude of each band. The board is supplied with regulated DC (3.5VDC to 5.5VDC). The multiplexor is controlled by a reset and a strobe, permitting multiplexor readout with only two pins.
