Syntax

#include <cafe.h>
#include <cafe/axfx.h>

typedef enum _AXFX_SAMPLE_RATE
{
    AXFX_SAMPLE_RATE_32000,
    AXFX_SAMPLE_RATE_48000,
} AXFX_SAMPLE_RATE;


typedef enum _AXFX_COMPRESSOR_MODE
{
    AXFX_COMPRESSOR_MODE_2CH,
    AXFX_COMPRESSOR_MODE_4CH,
    AXFX_COMPRESSOR_MODE_6CH,
} AXFX_COMPRESSOR_MODE;

BOOL AXFX2CompressorInit  (AXFX2_COMPRESSOR *compressor, AXFX_COMPRESSOR_MODE mode,
                           AXFX_SAMPLE_RATE sampleRate);

Parameters

compressor Pointer to an AXFX2_COMPRESSOR structure with valid user parameters set.
mode AXFX_COMPRESSOR_MODE enum specifying the number of channels to process.
sampleRate AXFX_SAMPLE_RATE enum specifying the sample rate of the audio signal.

Return Values

TRUE if successful; FALSE if a failure occurs or a parameter is invalid.

Description

The AXFX2CompressorInit initializes a compressor effect given an AXFX2_COMPRESSOR structure with valid user parameters, the number of channels (specified by mode), and the input signal sample rate (specified by sampleRate). This function allocates and initializes all the required runtime memory used by the delay lines and related processing steps. The user must configure the AXFX2_COMPRESSOR structure's user parameters prior to calling this function. This function should be called only once on a compressor structure. Generally the sample rate should match the sample rate initialized with AXGetInitWithParams and returned by AXGetInputSamplesPerSec.

Modes

AXFX_COMPRESSOR_MODE_2CH Two channel effect which processes two channels.
AXFX_COMPRESSOR_MODE_4CH Four channel effect which processes four channels.
AXFX_COMPRESSOR_MODE_6CH Six channel effect which processes six channels.

Sample Rates

AXFX_SAMPLE_RATE_32000 32kHz audio data.
AXFX_SAMPLE_RATE_48000 48kHz audio data.
