RE: Modern (bit) lossless digital volume control

Posted by rogerh113 on April 14, 2025 at 07:30:24:
Any particular reason you want to do volume control in the digital realm rather than in analog?

Digital takes samples of the signal, digitizes the samples, and after it is done processing it converts the signal back to analog. Inherent in this sampling are approximation errors (limited bit count), with approximation errors also stacking up in the processing and reconversion.

Perhaps digital works nicely in computers, where life is 0 or 1, but that is not an analog music signal. I am surprised about how nice a good CD system can sound (with top flight components), but I certainly would not send the signal through a chain of 'digital processors' and expect anything useful to come out.

Consider a TVC, where the signal remains in the analog realm and it is effectively lossless.
