With audio input

Tested bad

  • Built-in Raspberry 1/8" audio jack. The onboard RBPi soundcard is not suitable at all. It's PWM based (no DAC!) and only 10 bits of resolution. Also, it has a huge latency. Forget getting a decent result with it. You have to use a decent soundcard (with a DAC!) for RBPi.
  • USB audio interfaces (latency problems)
