DITHER SELECTOR OPTIONS
Position Dither and Noise Shaping
1 Positions the noise shaped dither to the very top of the audio spectrum at a
level of +30dB above the quantise noise floor.
The ears are very insensitive at this frequency, hence the noise is
inaudible, resulting in subjectively clean signals with wide dynamic range.
Adding extreme HF EQ boost at a later stage is NOT recommended.
2 The same frequency as 1 (above) with only +20dB of boost.
The reduction in level slightly increases distortion, but the tolerance to HF
EQ on replay is increased.
3 Shaped dither above 17KHz @ +30dB.
4 Shaped dither above 17KHz @ +20dB.
5 Dual slope filtered dither above 16KHz @ +10dB.
A particularly effective setting combining subjective neutrality with a
worthwhile increase in dynamic range and high tolerance to post HF EQ.
6 Shaped dither above 14KHz @ +20dB.
7 Shaped dither above 14KHz @ +15dB.
8 Shaped dither above 12KHz @ +15dB.
9 Smooth, dual-slope filtered dither above 10KHz @ +10dB.
A relatively gentle noise shaping with a worthwhile increase in dynamic
range and a neutral sound.
10 Shaped dither above 10KHz @ +10dB.
11 White noise dither. No noise shaping.
12 Dither / Noise shaping OFF.
Caution as a truncated word length will give distortion.
