Detailed Description

Regular sound that can be played in the audio environment.

sf::Sound is the class to use to play sounds.

It provides:

Control (play, pause, stop)
Ability to modify output parameters in real-time (pitch, volume, ...)
3D spatial features (position, attenuation, ...).

sf::Sound is perfect for playing short sounds that can fit in memory and require no latency, like foot steps or gun shots. For longer sounds, like background musics or long speeches, rather see sf::Music (which is based on streaming).

In order to work, a sound must be given a buffer of audio data to play. Audio data (samples) is stored in sf::SoundBuffer, and attached to a sound with the setBuffer() function. The buffer object attached to a sound must remain alive as long as the sound uses it. Note that multiple sounds can use the same sound buffer at the same time.

Usage example:

sf::SoundBuffer buffer;
buffer.loadFromFile("sound.wav");
sf::Sound sound;
sound.setBuffer(buffer);
sound.play();

Returns: Position of the sound

See also: setPosition

◆ getStatus()

Status sf::Sound::getStatus ( ) const

virtual

Get the current status of the sound (stopped, paused, playing)

Returns: Current status of the sound

Reimplemented from sf::SoundSource.

◆ getVolume()

float sf::SoundSource::getVolume ( ) const

inherited

Get the volume of the sound.

Returns: Volume of the sound, in the range [0, 100]

See also: setVolume

◆ isRelativeToListener()

bool sf::SoundSource::isRelativeToListener ( ) const

inherited

Tell whether the sound's position is relative to the listener or is absolute.

Returns: True if the position is relative, false if it's absolute

See also: setRelativeToListener

◆ operator=()

Sound& sf::Sound::operator= ( const Sound & right )

Overload of assignment operator.

Parameters

right Instance to assign

Returns: Reference to self

◆ pause()

void sf::Sound::pause ( )

virtual

Pause the sound.

This function pauses the sound if it was playing, otherwise (sound already paused or stopped) it has no effect.

See also: play, stop

Implements sf::SoundSource.

◆ play()

void sf::Sound::play ( )

virtual

Start or resume playing the sound.

This function starts the stream if it was stopped, resumes it if it was paused, and restarts it from beginning if it was it already playing. This function uses its own thread so that it doesn't block the rest of the program while the sound is played.

See also: pause, stop

Implements sf::SoundSource.

◆ resetBuffer()

void sf::Sound::resetBuffer ( )

Reset the internal buffer of the sound.

This function is for internal use only, you don't have to use it. It is called by the sf::SoundBuffer that this sound uses, when it is destroyed in order to prevent the sound from using a dead buffer.

◆ setAttenuation()

void sf::SoundSource::setAttenuation ( float attenuation )

inherited

Set the attenuation factor of the sound.

The attenuation is a multiplicative factor which makes the sound more or less loud according to its distance from the listener. An attenuation of 0 will produce a non-attenuated sound, i.e. its volume will always be the same whether it is heard from near or from far. On the other hand, an attenuation value such as 100 will make the sound fade out very quickly as it gets further from the listener. The default value of the attenuation is 1.

Parameters

attenuation New attenuation factor of the sound

See also: getAttenuation, setMinDistance

◆ setBuffer()

void sf::Sound::setBuffer ( const SoundBuffer & buffer )

Set the source buffer containing the audio data to play.

It is important to note that the sound buffer is not copied, thus the sf::SoundBuffer instance must remain alive as long as it is attached to the sound.

Parameters

buffer Sound buffer to attach to the sound

See also: getBuffer

◆ setLoop()

void sf::Sound::setLoop ( bool loop )

Set whether or not the sound should loop after reaching the end.

If set, the sound will restart from beginning after reaching the end and so on, until it is stopped or setLoop(false) is called. The default looping state for sound is false.

Parameters

loop	True to play in loop, false to play once

See also: getLoop

◆ setMinDistance()

void sf::SoundSource::setMinDistance ( float distance )

inherited

Set the minimum distance of the sound.

The "minimum distance" of a sound is the maximum distance at which it is heard at its maximum volume. Further than the minimum distance, it will start to fade out according to its attenuation factor. A value of 0 ("inside the head of the listener") is an invalid value and is forbidden. The default value of the minimum distance is 1.

Parameters

distance New minimum distance of the sound

See also: getMinDistance, setAttenuation

◆ setPitch()

void sf::SoundSource::setPitch ( float pitch )

inherited

Set the pitch of the sound.

The pitch represents the perceived fundamental frequency of a sound; thus you can make a sound more acute or grave by changing its pitch. A side effect of changing the pitch is to modify the playing speed of the sound as well. The default value for the pitch is 1.

Parameters

pitch New pitch to apply to the sound

See also: getPitch

◆ setPlayingOffset()

void sf::Sound::setPlayingOffset ( Time timeOffset )

Change the current playing position of the sound.

The playing position can be changed when the sound is either paused or playing. Changing the playing position when the sound is stopped has no effect, since playing the sound will reset its position.

Parameters

timeOffset New playing position, from the beginning of the sound

See also: getPlayingOffset

◆ setPosition() [1/2]

void sf::SoundSource::setPosition	(	float	x,
		float	y,
		float	z
	)

inherited

Set the 3D position of the sound in the audio scene.

Only sounds with one channel (mono sounds) can be spatialized. The default position of a sound is (0, 0, 0).

Parameters

x	X coordinate of the position of the sound in the scene
y	Y coordinate of the position of the sound in the scene
z	Z coordinate of the position of the sound in the scene

See also: getPosition

◆ setPosition() [2/2]

void sf::SoundSource::setPosition ( const Vector3f & position )

inherited

Set the 3D position of the sound in the audio scene.

Only sounds with one channel (mono sounds) can be spatialized. The default position of a sound is (0, 0, 0).

Parameters

position Position of the sound in the scene

See also: getPosition

◆ setRelativeToListener()

void sf::SoundSource::setRelativeToListener ( bool relative )

inherited

Make the sound's position relative to the listener or absolute.

Making a sound relative to the listener will ensure that it will always be played the same way regardless of the position of the listener. This can be useful for non-spatialized sounds, sounds that are produced by the listener, or sounds attached to it. The default value is false (position is absolute).

Parameters

relative True to set the position relative, false to set it absolute

See also: isRelativeToListener

◆ setVolume()

void sf::SoundSource::setVolume ( float volume )

inherited

Set the volume of the sound.

The volume is a value between 0 (mute) and 100 (full volume). The default value for the volume is 100.

Parameters

volume Volume of the sound

See also: getVolume

◆ stop()

void sf::Sound::stop ( )

virtual

stop playing the sound

This function stops the sound if it was playing or paused, and does nothing if it was already stopped. It also resets the playing position (unlike pause()).

See also: play, pause

Implements sf::SoundSource.
