Mode0 â use to retain existing logic in encoder w.r.t cutoff frequency handling. Mode1 â Use to enable a global cutoff frequency. For example, for usecases with requirement to limit cutoff frequency to a particular level irrespective of configuration(sampling rate, bit rate etc.,) Mode2 â Use to enable a cutoff frequency table based on bitrate range. For example, user can choose to configure different cutoff frequencies for different bitrate ranges, with upto 6 levels. Mode3 â Use to disable cutoff frequency logic in the encoder. This will pick max cutoff frequency as default, i.e., half the sampling rate. All other values are reserved. }
This value will be picked as global cutoff frequency when âfreq_cutoff_modeâ field is set to âmode1â. NOTE : Any value above maximum cutoff frequency will be discarded and cutoff frequency will be set to max cutoff frequency.}
This value and immediately following variable size array based on num_cutoff_levels will be chosen for cutoff frequency configuration when âfreq_cutoff_modeâ field is set to âmode2â.}
