Member Function Documentation

Filter()

reverb::Filter::Filter

Constructs a Filter object with optional frequency/gain/Q parameters.

The Filter object is constructed from the processor pointer and from the optional frequency/gain/Q parameters. The frequency is the cut-off frequency of the derived LowShelfFilter/HighShelfFilter and the center frequency of the PeakFilter class.

Parameters

[in]	processor	Pointer to main processor
[in]	freq	Band frequency
[in]	gain	Band gain
[in]	q	Q factor
