Returns
Current sample.
u32 ASND_GetSamplesPerTick ( )

Retrieves the samples sent from the IRQ in one tick.

Returns
Samples per tick.
u32 ASND_GetTime ( )

Returns the global time.

The time is updated from the IRQ.

Returns
The current time, in milliseconds.
void ASND_Init ( )

Initializes the ASND lib and fixes the hardware sample rate to 48000.

Returns
None.
s32 ASND_Is_Paused ( )

Returns sound paused status.

Returns
1 if paused, 0 if unpaused.
void ASND_Pause ( s32  paused)

Used to pause (or unpause) the sound.

Note
The sound starts paused when ASND_Init() is called.
Parameters
[in]pausedIf 1, sound is paused; sound can be unpaused with 0.
Returns
None.
void ASND_SetCallback ( void(*)()  callback)

Sets a global callback for general purposes.

This callback is called from the IRQ.

Parameters
[in]callbackCallback function to assign.
Returns
None.
void ASND_SetTime ( u32  time)

Set the global time.

This time is updated from the IRQ.

Parameters
[in]timeFix the current time, in milliseconds.
Returns
None.
