Everything is a kind of sound. If not, there would be one set of headphones, one amp, one dac, and one pair of speakers. Etc.

That's where people falter. Source should be accurate, coloring job should be left to down the line equipment.

Accuracy is a good point, but what accuracy do you mean? As measured or as perceived? I gave you an example about DSP pre-procesing and you missed it.

Yep, this audio scientology stuff is toxic

So you mean to say all r2r dacs are nos ? And if not, os in r2r dacs is magically done without any digital processing and dither ?

So you mean to say perceived accuracy is inversely proportional to measured accuracy ?

Do you need dither for the source that is already dithered?

 

[gimmeheadroom]

Dither, thither, and yon. All needed

Tell me first, do you like 20kHz BW or 90kHz BW jitter test?

sounds very familiar !

 

[sajunky]

Sounds fabulous, both. I still enjoy Christmas.

Btw that does not explain how os takes place in r2r dacs.

isn't oversampling in r2r dac digital processing ? Or all r2r dacs are nos ? Did you know that your "beloved yggy" uses some saucy burrito filter for oversampling. Now don't tell me that dither is not required in digital processing.

Oversampling filter and dithering has literally nothing to do with each other, the burrito thing does zero dithering

Noise shaping?
A bell rang in a wrong Church.

Trying to help. .LOL.

Ok, you mean to say oversampling does not require digital processing ? And digital processing does not require dither when converting from higher bits to lower bits ? Now don't tell me why digital processing requires higher bits for processing ? I mean what has happened to you engineers ? Can you oversample a 16bit 44.1khz files to 4x or 8x with "16bit" maths ? Will you not end up with lesser accurate bits than 16 if you use 16bit maths ? If you have some value which is accurate to 4th decimal place and you do some multiplication and division in a calculator which is also accurate upto 4th decimal place only , will you get the results which will be accurate to 4th decimal place ? Obviously you will use a calculator with higher decimal place accuracy so that there are no or lesser errors during rounding off to 4th decimal place. Similarly a 16bit 44.1khz file will be 4x oversampled using 32 or even 64bit maths and since r2r dac accepts full word length (16,18 or 20bit depending upon the r2r ladder capability), so lower bits out of 32 or 64bits after oversampling will be plainly discarded or chopped off after dither. Dither adds randomness to rounding off errors and random errors are less objectionable. Now for audio use, dither is low level random audio noise and for video it will be low chroma or luma noise. To avoid dither noise being audible during low volume music passages, the dither noise can be shifted to inaudible band which is called noise shaping. Now go get into the papers of burrito filter or sharc chip specs and see whether it uses 16bit processing for oversampling. And whether it uses dither or not. Eagerly waiting for your " engineering expertise"
