Dithering Options
No dithering, math. rounding of sample value: This mode converts the signals of 32-bit
float via precise mathematical rounding without dithering. The rounding involved makes
sure that surplus commas are not simply removed, and it also prevents signal distortions.
Dithering with linear spread noise: This converts audio data at 32-bit float via dithering
with noise featuring amplitude values that occur at regular intervals. The noise level may be
set via the "Dithering depth in bits" option.
Dithering with triangular spread noise (standard dithering): In this mode, audio data at
32-bit float is converted via dithering with noise featuring amplitude values split into
triangular intervals. This means that values are more regular in the medium range and less
often at the maximum or minimum values. This type of dithering usually creates better
results than linear dithering. The noise is not modulated through the signal, resulting in a
fading signal being enveloped by one constant noise signal.
Dithering depth in bits: This sets the level of the noise used in dithering. Input is in bits.
Use this option to specify how many bits of the resulting 16-bits should be affected by
dithering. In most cases, values between 0.5 and 2 will produce good results. Increase the
value until distortion effects are no longer audible. Provided you cannot perceive any
distortion effects, values below 0.5 are usually sufficient. If you would like to add more
severe noise to your signal, try entering values between 8 and 12.
POW-r dithering/Smart Dithering
POW-r #1 (dithering): This function uses a special dithering curve to minimize quantization
noise.
