Hello! I have some basic knowledge with microprocessors and I want to increase my knowledge. I've been having problems finding a microcontroller that could help me. This is the project I need to do:
I need to receive an audio signal. Convert it to digital. Process it and then convert it again to analog and transmit it as output audio signal with a different volume according to a test done while processing.
I know I need a micro with ADC & DAC embedded. I know PWD might help. Do I need amps for the phone jacks? I also know I need a microcontroller with an audio codec embedded to make it easier (I still have problems understanding this audio codec thing, is it a code, is it a component?)
Hope I can find some help in this forum, thanks in advance for your attention!

Let me explain: While the audio data is being processed it should be able to detect silence, immediately a beep is transmitted at a certain volume and the person listening need to push a button/switch. If the person fails to do this, it means they couldn't hear the beep and the volume must be decreased
