This version has multiple changes from the previous version, like:
- Can handle stereo signals.
- Display format is 18+1+1( to display 18 bands of frequencies and Left Right signal level) .
- USB adapter for easy upgrade.
- Dedicated RTC with battery back-up.
- Added two usart connectors to create cascade spectrum analyzers( to create large display from boards like this ).
- A microcontroller twice faster that previous and multiple hardware advantages that increase velocity of signal processing and rendering to display.

hi.
i'm from viet nam
I want to buy an Audio Spectrum Analyzer V4.0 circuit of you.
I want only the output signal to be displayed rather than led.
please mail me: duong.dt7 @ gmail.com
waiting for your mail, Have a good day
The stereo version looks good! I can't wait to see a demo of it on YouTube :-)
Now it is in development stage, when strictly necessary functions and drivers will be ready I will post a video with this stereo audio spectrum analyzer.
do you do the decoding using the mcu or some sort of special chip ?
All functions is processed by the mcu.
Converting, decoding, displaying and other functions.
