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.
peq_frequency Frequency Of Parametric Equalizer Band
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.
