Are sample rate converters used?
No, that’s where Pro64’s variable sample rates come in. With a range of about ±10% from the nominal rate, the Pro64 network can sync to virtually any clock it’s presented with. That’s important because sample rate converters actually change the audio data to make the samples align between two devices whose clocks are slightly different (even if their nominal rates are the same). Once the audio data has been changed by a sample rate converter, it can’t be changed back.
