Hi, I'm not to certain about how to understand the analogue input capabilities of the Arduino, or its total processing power. Here's the project I'd like to construct. A mini graphic or parametric equaliser and compressor. Audio into an analogue input, digitally modified and then back out a PWM output. As I understand it some filtering has to be done to turn the pulses into a useful sound, similiar to a Class D amplifier's operation.
Can an Arduino be used to accomplish such a task, or alternately is there a DSP IC that could be controlled via the Arduino that could do it? Thanks,
