Up next open source twin audio visualizer 69 channels in stereo!

Posted on June 9, 2022 by Mark Donners

Got my pcb proto ready. This is a Audio Visualizer that will be available as open source. It has two display. The first display will show a stereo VU meter, the old fashion way: imitating a needle.. while the other display has several features one of those is a stereo 69 channel spectrum analyzer…and it’s really fast! so that’s 140 channels in total! ( L+R VU, L69 +R69)
The pcb will include hardware to implement line in, line out, mic in…input for potmeters and switches and two outputs for pixelled matrix or ledstrips………..So excited to get this out there!
The PCB was sponsored by @PCBWay
And the main sketch that I started with was created by DIYlab.de
