# al\_attach\_sample\_instance\_to\_voice(3)

Allegro 5 API

## NAME

al\_attach\_sample\_instance\_to\_voice - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_audio.h>
  bool al_attach_sample_instance_to_voice(ALLEGRO_SAMPLE_INSTANCE *spl,
     ALLEGRO_VOICE *voice)
  ```

## DESCRIPTION

Attaches a sample instance to a voice, and allows it to play. The instance’s gain and loop mode will be ignored, and it must have the same frequency, channel configuration and depth (including signed-ness) as the voice. This function may fail if the selected driver doesn’t support preloading sample data.

At this time, we don’t recommend attaching sample instances directly to voices. Use a mixer inbetween.

Returns true on success, false on failure.
