LED Audio Spectrum Analyzer DIY Tutorial
This is an Audio Spectrum Analyzer ♥
The Spectrum Analyzer is a special type of a sound Level Meter. Consequently, it allows the engineer to examine the amplitude versus the frequency spectrum of a sound. They use multiple sets of filter networks and vertical colums display the information arranged from Low to High frequencies, Left to Right. In addition, these analyzers usually have third-octave spacings between the frequencies within a range between 20hz to 20 kHz.
