Description

Each of these functions performs multiplication by a scalar plus addition.

Parameters

Each of the functions takes the following arguments:

src1dst

The first input and the output signal array.

src2

The second input signal array.

c

Scaling factor. The scaling factor is in Q15 format. In the stereo version; c[0] contains the scaling factor for channel 0, and c[1] holds the scaling factor for channel 1.

n

Number of samples in the input signal arrays.

Return Values

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