NNS_SndCaptureSetPostOutputEffectCallback

Syntax

#include <nnsys/snd.h>

typedef void (*NNSSndCaptureCallback)(
    void* bufferL,
    void* bufferR,
    u32 len,
    NNSSndCaptureFormat format,
    void* arg
);

void NNS_SndCaptureSetPostOutputEffectCallback(
        NNSSndCaptureCallback func,
        void* arg );

Arguments

`func`	This is the callback function pointer
`arg`	This is the parameter that becomes the callback function argument

Return Values

None.

Description

Registers the output effect post-process callback.

While the NNS_SndCaptureStartOutputEffect function is performing output effect processing, the registered callback function indicated by func is called immediately after this processing. To call a callback function immediately before the output effect processing, register the callback function with the NNS_SndCaptureSetOutputEffectCallback function.

The arguments for the func callback function are the pointer to the starting address for the L component bufferL, the pointer to the starting address for the R component bufferR, and the buffer size len. The format format always takes NNS_SND_CAPTURE_FORMAT_PCM16, which indicates 16-bit PCM. The same value as the argument for NNS_SndCaptureSetPostOutputEffectCallback is passed to the user argument arg.

Note

Unlike the callback functions of the NNS_SndCaptureStartEffect function, the buffer that is passed can be accessed only from inside the callback function.
