Noise and distortion are inevitable. Interestingly, though, noise can sometimes increase resolution...

How did you discover this relation?
I have made some tests, and found that people actually prefer some distortion.
Magura 🙂
By reading about sampling theory when I suddenly had to become an expert on digital oscilloscopes to pass a job interview.😀
Re: Re: Re: Loss of Information
Perhaps the addition of 'unwanted stuff' cancel some of the wanted stuff. 😀
Whatever you prefer, the fact is information get lost throughout the whole recording and playback process.

Anything you care to elaborate?
This is quite interesting, as I have only come to the point of recognizing the effect.
Magura 🙂
For as long as there is no "reference" for the listener to consider as "absolutely neutral" or "correct",resolution and other aspects of a recording is purely a matter of perception/personal preference.

Dithering is the addition of noise to a digital system to increase resolution...

The result is that the analog output of the digital system *sounds* 😉 better. Instead of correlated distortion products that sound objectionable, you get noise, often below the audibility threshold, and much less objectionable.
But I guess you know all that already 😉

It doesn't.
It applies in particular to the A/D process where adding gaussian(?) noise into the signal and then averaging the digital ouput over a number of conversions provides a real increase in resolution.
Not relevant to (one-shot) audio, great for 'scopes and DVMs, if time is available.

Er isn't it only used in a bit reduction/conversion. Like 24-bit to 16-bit? At least this is the only time I use it and I really hope my A/D is not adding gaussian noise to my signal 🙂
I said it didn't apply to analog (audio).
How / why do you use an A/D to reduce 24 bit to 16 bit? That is easily does in software in the digital domain.

Some tubes, yes. I shoot for (and get) noise at -100dB or better in my tube stuff, so it's not generally a technology limitation.

Not perhaps a technology limitation,but surely a welcome musicality view(for me at least)

I've made some tests with identical circuits, with different noise figures, the lowest distortion figure was not preferred by all.

Speaking of adding noise, I had a strange experience the other day. Was testing a driver, full range. The day was hot so I tuned on the fan. An increase in noise floor, no big deal. A little later I moved the fan so it was between me and the driver.
Strange change in sound, to be sure. Not the "singing into the fan" effect I knew from childhood, but a decrease in bass.
After a few back and forths, it become eveident that it was an increase in the upper mids that the fan added, not a loss of bass. . Not sure what was going on there, but not what was expected - a Tonal balance change.
