# al\_set\_audio\_stream\_pan(3)

Allegro 5 API

## NAME

al\_set\_audio\_stream\_pan - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_audio.h>
  bool al_set_audio_stream_pan(ALLEGRO_AUDIO_STREAM *stream, float val)
  ```

## DESCRIPTION

Set the pan value on an audio stream. A value of -1.0 means to play the stream only through the left speaker; +1.0 means only through the right speaker; 0.0 means the sample is centre balanced. A special value [ALLEGRO\_AUDIO\_PAN\_NONE(3)](/ALLEGRO_AUDIO_PAN_NONE/3.md) disables panning and plays the stream at its original level. This will be louder than a pan value of 0.0.

Returns true on success, false on failure. Will fail if the audio stream is attached directly to a voice.
