Check the headers. From AudioHardware.h

    @constant       kAudioSubDevicePropertyDriftCompensationQuality
                        A UInt32 that controls the trade-off between quality
and CPU load in the
                        drift compensation. The range of values is from 0 to
128, where the lower
                        the number, the worse the quality but also the less CPU
is used to do the
                        compensation.

        Daniel.
