Description
This parameter sets the frequency (in Hz) of the specified parametric equalizer band. In the case of peaking
and notch types, this is the frequency at which the filter applies maximum (or minimum) gain. For all-pass
filters, this is the frequency at which the phase shift is 180 degrees. For conference link physical channels,
the band index must be between 1 and 5. For all other physical channels, the band index must be between
1 and 10.
