Function Documentation

AHX_Init()

int AHX_Init ( )

extern

AHX Init

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

Definition at line 48 of file ahx_rpc.c.

AHX_LoadSongBuffer()

int AHX_LoadSongBuffer ( char *  songdata, int  songsize  )

extern

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 175 of file ahx_rpc.c.

References iop_readwrite().

Referenced by AHX_LoadSong().

AHX_LoadSong()

int AHX_LoadSong ( char *  filename )

extern

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 199 of file ahx_rpc.c.

References AHX_LoadSongBuffer().

AHX_SubSong()

int AHX_SubSong ( int  songNo )

extern

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_SetVolume()

int AHX_SetVolume ( int  volumePercentage )

extern

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 117 of file ahx_rpc.c.

AHX_SetBoost()

int AHX_SetBoost ( int  boostValue )

extern

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 132 of file ahx_rpc.c.

AHX_ToggleOversampling()

int AHX_ToggleOversampling ( )

extern

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 147 of file ahx_rpc.c.

AHX_Quit()

int AHX_Quit ( )

extern

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 161 of file ahx_rpc.c.

AHX_Play()

int AHX_Play ( )

extern

AHX Play

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

Definition at line 74 of file ahx_rpc.c.

AHX_Pause()

int AHX_Pause ( )

extern

AHX Pause

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