Gb sound play

Description

// wav file:
int8_t gb.sound.play( const char* filename , bool loop = false )
// pattern:
int8_t gb.sound.play( const uint16_t* pattern , bool loop = false )
// raw buffer:
int8_t gb.sound.play( const uint8_t* buffer , uint32_t length , bool loop = false )
// custom handler:
int8_t gb.sound.play( Sound_Handler* handler , bool loop = false )

gb.sound.play will start playing sound from various sources. They return a track identifier or -1 if failed (no available channel).

The Gamebuino's 4 channel mixer allow to play up to 4 sound at the same time.
  • Wav file Plays an 8-bit unsigned wav file with a bitrate of 44.1kHz (max. sound frequency of 22050Hz)
  • Pattern Plays a pattern
  • Raw Buffer Plays a raw unsigned 8-bit buffer. The length of the buffer is determined automatically. If that fails (as in, your program won't compile) manually specify the length.
  • Custom Handler Play a custom sound handler

Parameters

  • (mixed) source: see above
  • bool loop: if true the sound will loop over and over forever
     Pattern example

Returns

int8_t: track identifier on success or -1 on failure

Example

#include <Gamebuino-Meta.h>

void setup() {

gb.begin();

}


void loop() {

while(!gb.update());

if (gb.buttons.pressed(BUTTON_A)) {

// let’s play TEST.WAV from the sd card!

gb.sound.play(“TEST.WAV”);

}

}
