I am new to Arduino stuff. I would like to connect to Arduino Ethernet with PoE module an audio input (from a PC or an Audio Mixer) and do some audio processing.
Is there is any module that can accept mini-jack audio input? Or is there is any guide so i can create my own circuit.
Did you want to digitize the audio? The 16 MHz Arduino can acquire only 9259 10-bit samples per second (about 4.6 KHz bandwidth). You can get 76,900 samples per second (~38.5 KHz bandwidth) at lower resolution... how much lower they don't seem to say.
