44.1/8-bit byproduct with the 44.1/16-bit original?
Such test with 44.1/8 file is pointless, with tons of audible noise. There is not enough space for noise shaping. Of course I did that.
My point is different - to show that even 8 bit resolution done with psychoacoustically proper dither does not degrade the perceived sound in the way that one would expect. Regardless the single number SINAD of less than 40 dB. I want to show that the single number 20kHz BW SINAD is pointless, from the perception point, without knowledge of signal spectrum.
SINAD = 37.3 dB
SINAD = 35.1 dB
Regarding your opinion of:
The bit depth is not variable here, the bit depth is 8 bit. Please read the post #36 again. ENOB is variable but only in case that we accept lower measuring bandwidth than 20kHz. For 20kHz BW, ENOB is low again.the variable of bit-depth
