+This is the device to host sample rate in kilo samples per second (kS/s). The sample rate can be as low as 48 kS/s so there is no need for software decimation. Note that at 48 kS/s some slight rate mismatch can appear with the audio that has the same nominal rate. This may cause some occasinal audio samples drops however hardly noticeable.
