Hello everyone !
I am working on noise reduction and I wanted to do some experiments with an arduino. I took an arduino which get music (as an example) in input by jack. It also has a microphone and in a first try the goal is to get as an output the music - the noise around... To act like a kind of noise reducing system. Then I will do a better signal treatment. The goal is to use the system as an audio treatment unit.
Here's a simple sketch and the system to amplify the audio signal.
First could you tell me if there is a problem in my sketches, please.
Then, I wonder where should I get the output signal ? I mean, will it works on PWM ?
Thanks in advance !
