What’s Wrong with Digital Volume Controls?

With a digital volume control, the peak signal level is reduced, but the underlying noise remains the same -- consequently, there is a reduction in dynamic range. The degree to which this loss of dynamic range is a problem depends on the inherent noise level of the DAC.

Many of today’s hi-fi amplifiers feature a “clicking” digital volume control circuit, but this is only rarely a real stepped attenuator based on a wafer switch. In nearly all cases, this expensive system is based on a normal potentiometer, whose spindle is fitted with a mechanical construction to simulate the stepping movement.

• A Digital volume control with access to the DAC internal data path will behave just like the analog one until it reaches the noise floor of the analog components of the DAC. • -135dB in the ESS Sabre DAC The signal is decreasing as we requested And the noise will fall as well until the DAC noise floor is reached D vs A Volume 17 of 39

Most digital audio formats do not support encoding volume level as metadata, so there is no way to implement a standardized, global digital audio volume control for a standard S/PDIF output, period. There are only four bits available for this use in the standard & they are rarely used for metadata, especially in consumer gear.
