Macro Definition Documentation

AHX_BINDRPC

#define AHX_BINDRPC

(

)

Value:

{ \
    int ret; \
    ret = AHX_BindRpc_Impl(); \
    if (ret) \
        return ret; \
}

IOP_MEM

#define IOP_MEM   0xbc000000

EE mapped IOP mem

Definition at line 31 of file ahx_rpc.c.

Function Documentation

AHX_Init()

int AHX_Init

(

)

AHX Init

Sends a call the the loaded AHX IRX, telling it to set things up ready for loading a song.

Definition at line 75 of file ahx_rpc.c.

AHX_LoadSong()

int AHX_LoadSong

(

char *

filename

)

AHX LongSongBuffer

This loads a song from disk etc. It loads the songdata into memory and passes it to LongSongBuffer.

Returns

number of subsongs.

Definition at line 162 of file ahx_rpc.c.

AHX_LoadSongBuffer()

int AHX_LoadSongBuffer	(	char *	songdata,
		int	songsize )

AHX LongSongBuffer

This loads a song from a buffer in memory. It copies [songsize] bytes from [songdata] to the IOP memory song buffer.

Returns

number of subsongs.

Definition at line 145 of file ahx_rpc.c.

AHX_Pause()

int AHX_Pause

(

)

AHX Pause

Sends a call the the loaded AHX IRX, telling it to pause the currently loaded song.

Definition at line 94 of file ahx_rpc.c.

AHX_Play()

int AHX_Play

(

)

AHX Play

Sends a call the the loaded AHX IRX, telling it to play the currently loaded song.

Definition at line 86 of file ahx_rpc.c.

AHX_Quit()

int AHX_Quit

(

)

AHX Quit

Sends a call the the loaded AHX IRX, telling it to quit. This frees up IOP mem, quites threads, deletes semaphores and all that jazz....

Definition at line 137 of file ahx_rpc.c.

AHX_SetBoost()

int AHX_SetBoost

(

int

boostValue

)

AHX Set Boost

Sends a call the the loaded AHX IRX, telling it to change the output boost value. Boost value multiplies the level of the output for the AHX Mixer. A boost value of 1 is twice as load as a boost value of 0. A boost value of 3 is twice as load as 2 etc etc (ala DB)

Definition at line 120 of file ahx_rpc.c.

AHX_SetVolume()

int AHX_SetVolume

(

int

volumePercentage

)

AHX Set Volume

Sends a call the the loaded AHX IRX, telling it to change the output volume of the SPU2. volumePercentage argument can range from 0 (0% silence) to 100 (100% full volume)

Definition at line 111 of file ahx_rpc.c.

AHX_SubSong()

int AHX_SubSong

(

int

songNo

)

AHX Play Subsong

Sends a call the the loaded AHX IRX, telling it to load subsong (songNo). You can determine the number of subsongs by checking the values returned by AHX_LoadSong() and AHX_LoadSongBuffer();

Definition at line 102 of file ahx_rpc.c.

AHX_ToggleOversampling()

int AHX_ToggleOversampling

(

)

AHX Toggle Oversampling

Switches oversampling on/off. Oversampling produces a smoother output sound but uses a lot more CPU power. It sounds nasty/slows down for a lot of songs - use with caution (or not at all)

Definition at line 129 of file ahx_rpc.c.

iop_readwrite()

void iop_readwrite	(	void *	addr,
		void *	buf,
		u32	size,
		u32	read )

Read/Write IOP Mem

This is an internal function used to read and write directly to IOP memory (write songdata to iop etc)

Definition at line 39 of file ahx_rpc.c.

Variable Documentation

songbuffer_addr

char* songbuffer_addr
