Upper frequency limit depends on the average bit rate.
It sounds better to reduce high frequencies responce than neglect the much
more audible medium frequencies.
With option "-k" you can suppress this feature, with "--lowpass <f_in_kHz>"
you can choose another limit. For my ears reducing the limit by 10% enhances
sound quality. The sound becomes more stable.
