I could tell the measurement wasn't good based on your comments, haha, just wasn't sure what I was looking at. OK, so 15 LSBs would be 4 bits off for 16 bit. Stuff like that is what I was asking if you had recommended reading for. Looking around myself as well to get myself educated, just wondered if you stumbled on anything easy to understand or digest. (Admittedly, this bit-level stuff, especially dealing with LSBs or MSBs went mostly over my head in that class, but maybe something is still stuck in my brain.)
Honestly, I don't think it would be that bad. Maybe the guys at Schiit would differ. :-)One way to test is to take that graph and make an error function. And then apply to the raw WAVE file. For every word (16bit), fuck up the value a little bit according to the function. And then see how it sounds.In terms of SD, you are probably right it doesn't apply since error will be different. But what happens (subjectively) to the WAVE file when we feed it into a DAC and add random noise per X sample after conversion of PCM to single or multi-bit?Again, all conjecture.
Well, would you use one of these DACs for audio?Do you want to be up to 15 LSBs off? Which for 16 bits, means 4 bits off? So how would you like to 3 to 4 bits louder than you are supposed to be from 0.20V to 0.40V on a 2V output DAC?
