Dynamic Listening Fatigue Reduction DLFR This is an audio sweetening tool that conditions the temporal envelope of the audio signal in multiple frequency bands The 6 vertical bars below the dial provide finer control over envelope conditioning in individual frequency bands with indicated center frequency values The higher the sliders the more conditioned the audio in that band is There are two associated slider controls which control respectively the tonal characteristics of overall audio and the refinement level of envelope conditioning Incoherent Component Suppression ICS CNE a ARE ERE 34 This module detects the incoherent components of the input audio and smoothes the corresponding audio component resulting in a sound that is easier to process by the human auditory perception system thus increasing the listen ability of the sound The slider controls for this module include a Start Frequency which specifies the frequency threshold above which the processing is done this can be varied from 4 kHz to 8 kHz The dial controls the intensity of processing done by the algorithm A new user can safely set the dial at 0 2 and the start frequency at about 6 8 kHz Multi Band Graphic Equalizer Eu s i This module equalizes the audio in 10 bands 446464545 according to the 10 slider setting For all the slider ee eee at the middle of the range equalizer is effectively flat Each slider can be moved between 5dB and 5dB T
