Description
This parameter sets the bandwidth (in octaves) of the specified parametric
equalizer band. In the case of peaking filters, this is the bandwidth at which the
gain is half the peak gain (in dB). For notch filters, this is the 3 dB bandwidth.
For all-pass filters, this is the bandwidth at which the phase shift is +/- 90
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.
