nc_level Noise Cancellation Level

Description

This parameter sets the amount of cancellation (in dB) applied by the noise

cancellation algorithm.

sig_gen_gain Signal Generator Gain

Description

This parameter sets the gain of the signal produced by the signal generator, in

dB. A gain of 0 dB will produce a signal that has the same RMS level as a sine

wave at -20 dBFS (the nominal signal level). This means that not all signal

types will have the same peak level, and some types may clip before a gain of

20 dB is applied.
