pygame.mixer.music

pygame module for controlling streamed audio

The music module is closely tied to pygame.mixer. Use the music module to control the playback of music in the sound mixer.

The difference between the music playback and regular Sound playback is that the music is streamed, and never actually loaded all at once. The mixer system only supports a single music stream at once.

Be aware that MP3 support is limited. On some systems an unsupported format can crash the program, e.g. Debian Linux. Consider using OGG instead.

pygame.mixer.music.load(filename) -> None
pygame.mixer.music.load(object) -> None

Load a music file for playback

This will load a music filename/file object and prepare it for playback. If a music stream is already playing it will be stopped. This does not start the music playing.

pygame.mixer.music.unload() -> None

Unload the currently loaded music to free up resources

This closes resources like files for any music that may be loaded.

New in pygame 2.0.0.

pygame.mixer.music.play(loops=0, start=0.0) -> None

Start the playback of the music stream

This will play the loaded music stream. If the music is already playing it will be restarted.

The loops argument controls the number of repeats a music will play. play(5) will cause the music to played once, then repeated five times, for a total of six. If the loops is -1 then the music will repeat indefinitely.

The starting position argument controls where in the music the song starts playing. The starting position is dependent on the format of music playing. MP3 and OGG use the position as time (in seconds). MOD music it is the pattern order number. Passing a startpos will raise a NotImplementedError if it cannot set the start position

pygame.mixer.music.rewind() -> None

restart music

Resets playback of the current music to the beginning.

pygame.mixer.music.stop() -> None

stop the music playback

Stops the music playback if it is currently playing.

pygame.mixer.music.pause() -> None

temporarily stop music playback

Temporarily stop playback of the music stream. It can be resumed with the pygame.mixer.music.unpause() function.

pygame.mixer.music.unpause() -> None

resume paused music

This will resume the playback of a music stream after it has been paused.

pygame.mixer.music.fadeout(time) -> None

stop music playback after fading out

This will stop the music playback after it has been faded out over the specified time (measured in milliseconds).

Note, that this function blocks until the music has faded out.

pygame.mixer.music.set_volume(value) -> None

set the music volume

Set the volume of the music playback. The value argument is between 0.0 and 1.0. When new music is loaded the volume is reset.

pygame.mixer.music.get_volume() -> value

get the music volume

Returns the current volume for the mixer. The value will be between 0.0 and 1.0.

pygame.mixer.music.get_busy() -> bool

check if the music stream is playing

Returns True when the music stream is actively playing. When the music is idle this returns False.

pygame.mixer.music.set_pos(pos) -> None

set position to play from

This sets the position in the music file where playback will start. The meaning of "pos", a float (or a number that can be converted to a float), depends on the music format. For MOD files, it is the integer pattern number in the module. For OGG it the absolute position, in seconds, from the beginning of the sound. For MP3 files, it is the relative position, in seconds, from the current position. For absolute positioning in an MP3 file, first call rewind(). Other file formats are unsupported. Newer versions of SDL_mixer have better positioning support than earlier. An SDLError is raised if a particular format does not support positioning.

Function set_pos() calls underlining SDL_mixer function Mix_SetMusicPosition.

New in pygame 1.9.2.

pygame.mixer.music.get_pos() -> time

get the music play time

This gets the number of milliseconds that the music has been playing for. The returned time only represents how long the music has been playing; it does not take into account any starting position offsets.

pygame.mixer.music.queue(filename) -> None

queue a sound file to follow the current

This will load a sound file and queue it. A queued sound file will begin as soon as the current sound naturally ends. Only one sound can be queued at a time. Queuing a new sound while another sound is queued will result in the new sound becoming the queued sound. Also, if the current sound is ever stopped or changed, the queued sound will be lost.

The following example will play music by Bach six times, then play music by Mozart once:

pygame.mixer.music.load('bach.ogg')
pygame.mixer.music.play(5)        # Plays six times, not five!
pygame.mixer.music.queue('mozart.ogg')

pygame.mixer.music.set_endevent() -> None
pygame.mixer.music.set_endevent(type) -> None

have the music send an event when playback stops

This causes pygame to signal (by means of the event queue) when the music is done playing. The argument determines the type of event that will be queued.

The event will be queued every time the music finishes, not just the first time. To stop the event from being queued, call this method with no argument.

pygame.mixer.music.get_endevent() -> type

get the event a channel sends when playback stops

Returns the event type to be sent every time the music finishes playback. If there is no endevent the function returns pygame.NOEVENT.
