    Audio Analyzer v2 SKU:DFR0126     Contents    1 Introduction 2 Technical Specifications 3 Connection Diagram 3.1 Sample code Introduction This module features the MSGEQ7 graphic equalizer display filter.It will give your arduino ears. Sound is broken down into seven frequency bands and the peak level for each band can be read. The seven frequencies measured are as follows: 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. This module can be used to create sound visualizers, detect patterns in music or add sound activation to your microcontroller. Technical Specifications 1. MSGEQ7 Data Sheet 2.
