4 bit example pictures[edit]

Would be interesting to see not dithered and dithered pictures with an unoptimized 16 colour vga standard palette. Sure, the first one will look terrible and the second on not really good, but they'll serve as good comparisons to the other pictures and show what's possible with very few colours.

Frequency domain[edit]

I deleted the sentence about the ear being more sensitive in the frequency domain. I'm an electrical engineer and this statement makes no sense. Frequency and time domain are two ways of representing the SAME signal. — (unsigned comment by 195.243.189.189, 2005-12-21 01:41:21)

Sound files need explanation[edit]

The two sample sound files are an excellent addition but need more explanatory text. Has dithering been added to the second sample? If so, what kind of dithering? It would be ideal if there were three samples: 16 bit original, 6 bit without dithering, 6 bit with dithering. Ross Fraser (talk) 21:32, 21 July 2010 (UTC)[reply]

These sound files are not particularly illustrative. It sounds like the dithered version has more than 1 LSB of noise. It is hard to hear the difference between 16-bit and 6-bit truncated. Perhaps we should redo with 3 or 4 bit truncation and best practice for level and shape for the dithered version. ~Kvng (talk) 19:01, 22 December 2022 (UTC)[reply]

Audio Spectra wrong[edit]

Sorry, but the Audio spectrum is wrong, if the 500 Hz sine would be correctly dithered, no harmonics will be seen. Nothing. Only the added noise will remain. — Preceding unsigned comment added by 91.51.96.47 (talk) 16:51, 21 July 2012 (UTC)[reply]

I agree. There seems to be issues with these 6-bit examples. See my comments above. ~Kvng (talk) 19:04, 22 December 2022 (UTC)[reply]
