Noise clock table

Note that the noise sampling frequency is the perceived pitch (due to overtones) even though it is double (Nyquist) that of the fundamental.

Value	Sampling Frequency	Pitch
00	0 Hz	off
01	16 Hz	C0 - 38¢
02	21 Hz	E0 + 33¢
03	25 Hz	G0 + 35¢
04	31 Hz	B0 + 7¢
05	42 Hz	E1 + 33¢
06	50 Hz	G1 + 35¢
07	63 Hz	B1 + 35¢
08	83 Hz	E2 + 12¢
09	100 Hz	G2 + 35¢
0A	125 Hz	B2 + 21¢
0B	167 Hz	E3 + 23¢
0C	200 Hz	G3 + 35¢
0D	250 Hz	B3 + 21¢
0E	333 Hz	E4 + 18¢
0F	400 Hz	G4 + 35¢
10	500 Hz	B4 + 21¢
11	667 Hz	E5 + 20¢
12	800 Hz	G5 + 35¢
