A source and an output can have the same sample rate while their sample values differ. Changing the volume or applying digital processing does not necessarily change the displayed rate.
That is why the Signal Explorer separates format, processing, transport and integrity. Select the processed PCM example: the rate stays the same, but the state is no longer bit-perfect.
