Function Documentation

sceVaudioChRelease()

int sceVaudioChRelease

(

void

)

Release a virtual output channel.

Returns

0 if success, < 0 on error.

sceVaudioChReserve()

int sceVaudioChReserve	(	int	samplecount,
		int	frequency,
		int	format
	)

Allocate and initialize a virtual output channel.

Parameters

samplecount	- The number of samples that can be output on the channel per output call. One of 256, 576, 1024, 1152, 2048. It must be a value between PSP_VAUDIO_SAMPLE_MIN and PSP_VAUDIO_SAMPLE_MAX.
frequency	- The frequency. One of 48000, 44100, 32000, 24000, 22050, 16000, 12000, 11050, 8000.
format	- The output format to use for the channel. One of PSP_VAUDIO_FORMAT_

Returns

0 if success, < 0 on error.

sceVaudioOutputBlocking()

int sceVaudioOutputBlocking	(	int	volume,
		void *	buffer
	)

Output audio (blocking)

Parameters

volume	- It must be a value between 0 and PSP_VAUDIO_VOLUME_MAX
buffer	- Pointer to the PCM data to output.

Returns

0 on success, an error if less than 0.

int sceVaudioSetAlcMode

(

int

mode

)

Set ALC(dynamic normalizer)

Parameters

mode	- The mode. One of PSP_VAUDIO_ALC_

Returns

0 if success, < 0 on error.

sceVaudioSetEffectType()

int sceVaudioSetEffectType	(	int	effect,
