uint32_t
Mode0 – use to retain existing logic in encoder w.r.t cutoff frequency handling. Mode1 – 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 – 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 – 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. }
uint32_t
This value will be picked as global cutoff frequency when ‘freq_cutoff_mode’ field is set to ‘mode1’. NOTE : Any value above maximum cutoff frequency will be discarded and cutoff frequency will be set to max cutoff frequency.}
uint32_t
This value and immediately following variable size array based on num_cutoff_levels will be chosen for cutoff frequency configuration when ‘freq_cutoff_mode’ field is set to ‘mode2’.}
