I am working on a project to make a speaker with reactive lighting. I need to be able to sample stereo audio at a decent rate for songs. The
audioRead () function can do about
8 kHz and I have heard you can push it up till
35 kHz but than you can only use it for mono and you cannot use the arduino for anything else.
Someone recommended that I use an ADC. What can it do for me?
Is the arduino's operating speed a limitation?
If not the arduino which other micro-controller is suitable for this purpose.
