No, the DSP routes audio paths internally at 44.1Khz, but it doesn't allow the StrongARM to sample those paths. On the Mk.2 we added an ADC, primarily to sample the microphone input, but it can see the other inputs as well if required. It runs at a fairly low sample rate because we had a convenient way to interface it into the StrongARM, and that's all we need for voice recognition or, say, RDS TA recording.
