I'm trying to modify a radio such that the output goes through some audio processing in a raspberry pi (using a usb audio dongle) before getting amplified.
The amp is TDA7266 but the radio is mono and uses only one channel.
I'm a beginner and I'm wondering what would be the best way to do this. Could I simply interrupt the signal right before it goes into the input pin on the TDA766? I.e. the signal would go USB-input -> RPI processing -> USB-output -> TDA7266 pin 4. I guess this would depend on the strength of the signal pre- and post-processing. I'm also a bit confused as to which ground reference I would be using in for the USB input this case.
As you can tell I'm a bit over my head - any tips would be much appreciated.
