In Reply to: RE: Modern (bit) lossless digital volume control posted by Leo loves music on April 13, 2025 at 12:07:50
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.
Follow Ups:
Now days, many streamers and DACs and AMPs have digital volume control. I just want to bring this to owners attention so they know what is lossless.

Merely because technology can create something does not mean it has merit. My comments above are still valid. The digital volume control acceptability depends on budget and what can be tolerated.
Technology often does translate to 'cheap' rather than desirable. Having worked in Silicon Valley for a couple of decades, it became obvious that some tech is useful, and a lot is not so much so.
Volume control works well in the digital domain, especially if you optimize system gain to work at the top end of its range. I know it is easy to assume price equals quality in the audiophile world so be reassured there are audio companies who will charge a lot for their implementation of digital volume control.
I am sure that the control of volume works well in digital volume control, it is the fidelity of the signal I am commenting on. I am making the assumption that signal fidelity is important.
When the signal goes into the digital volume control, it is digitized, processed, and reconverted to analog no matter what the volume setting is. Back to the fidelity of the digital volume control.
I think it is fine if people want to use a digital volume control. Just be aware of what it is and how it works. Everyone has their priorities and listening preferences.
With regards to fidelity, if the signal is already in the digital domain then a properly implemented digital volume control should equal, or better, any method of volume control once the signal is converted back to analog. Of course, YMMV, and comparisons would be necessary just don't throw the baby out before the bath.
And if you're purely analog, there is a whole host of imperfections to deal with so volume control is the least of your worries:)
