The option --cwlimit <freq> limits the unpredictability
measure computation. Above that frequency, a default
value will be used.
In the previous versions it was computed up to a fixed
index. This fixed index had the drawback, that at a
sampling frequency of 16 kHz the unpredictability measure
was computed up to 3 kHz only. The default value is now
a frequency of 8.9 kHz for all sampling frequencies, but
it can be set with this option.
The unpredictability measure is used by the tonality
function and controls the masking level within
scalefactor bands. (masking capabilities vary if the
sound is more tonal or atonal)
