Detailed Description

Function Documentation

audioInit()

void audioInit

(

void

)

Initialize the audio system.

Uploads the SPC700 driver (built into the lib as audio_driver_blob) through the IPL boot-ROM protocol and starts it, then verifies the command channel with a PING. Call once during game initialization; check audioIsReady() afterwards.

Note

Blocks for the duration of the upload (~a frame for the small driver). Interrupts stay enabled; the NMI handler does not touch the APU ports.

audioIsReady()

u8 audioIsReady

(

void

)

Returns

Non-zero if ready, 0 if still initializing

audioUpdate()

void audioUpdate

(

void

)

Process audio updates.

Call once per frame in your main loop. Handles command queue processing and streaming.
