Description
Description:When we developed this audio analysis module, we used a fully gold-plated PCB board, a gold-plated 8-pin socket, a gold-plated pin header, and a gold-plated adapter. The purpose is to ensure the quality of audio transmission, so that the analysis will be accurate and reduce interference.
The audio processing is an audio signal analysis IC based on the MSGEQ7 graphic equalization filter. The audio signal will be filtered into 7 frequency bands through this module. And can output the amplitude of each frequency band. The seven frequency bands are: 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. This module can be used to create an audio analyzer to track the frequency information of music so that your controller (Arduin0) can interact with the music.
It can be used to capture the music spectrum, make music interactive robots, process audio data reading, make lighting special effects, voice analysis, etc...
MSGEQ7 requires the typical amplitude of the input signal to be 20dB. The module provides a potentiometer for adjusting the input amplitude. Adjust this potentiometer appropriately to make the signal strength meet the sampling requirements of MSGEQ7.
