Description

Each of these functions applies a biquad IIR filter to a signal array.

The biquad IIR filter is represented by the following figure:

Parameters

Each of the functions takes the following arguments:

dst

Destination signal array.

src

Source signal array.

filter

Internal filter structure.

n

Number of samples in the source signal array.

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
