Resolution: DSD vs 16bit vs 24 bit
"Audio Myth: 24-bit Audio Has More Resolution Than 16-bit Audio" - link to article I received today by email from Benchmark Media Systems:

Tomcy6, AFAIK dither is not "done" but happens automatically. Imagine converting level that is exactly 50% between two LSB values. Because there is always some random noise LSB will oscillate 0 to +1 at about 50% rate. When value is at 3/4 then LSB will be on high side (+1 bit) 3/4 of the time. In playback it can be filtered to original value increasing resolution. As for the fancy words used in article: "Quantization noise" means simply a staircase. "Bigger quantization noise" mean taller steps. Higher frequency of quantization noise means more of the smaller steps etc. Filtering is basically smoothing off the staircase. |
