Description
Audio Spectrum Analyzer 10 Channel 100 LED Peak Hold
The filter quality of the Led Spectrum Analyzer is around 6, and the middle frequencies are 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz. J5 on the circuit changes the display style, you can choose to work as a classic vu-meter and bar. J4 is used to toggle the maximum amplitude value (peak hold). This Spectrum Analyzer project, in my opinion, is one of the most successful works of its period in hardware and software.
