It defines several properties for the sound: pitch, volume, position, attenuation, etc. All of them can be changed at any time with no impact on performances. .. rubric:: See also: :ref:`Sound `, :ref:`SoundStream ` Construction ------------ .. index:: pair: function; SoundSource .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1ae419e34472bdf604d75841a0215a6a3a: .. ref-code-block:: cpp :class: doxyrest-title-code-block SoundSource(const SoundSource& copy) Copy constructor. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - copy - Instance to copy Methods ------- .. index:: pair: function; setPitch .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a6ebc9019d048be4be32b2ea3a20c0a34: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setPitch(float pitch) 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. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - pitch - New pitch to apply to the sound .. rubric:: See also: :ref:`getPitch ` .. index:: pair: function; setVolume .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a3a2e0cf6ff2ee726a12450e91369ab2f: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setVolume(float volume) 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. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - volume - Volume of the sound .. rubric:: See also: :ref:`getVolume ` .. index:: pair: function; setPosition .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a8b1f39cca03ad22284344d58f0fb4dec: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setPosition(float x, float y, float z) 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). .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - 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 .. rubric:: See also: :ref:`getPosition ` .. index:: pair: function; setPosition .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a4850d9621033aeccf39ef9a83041165a: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setPosition(const :ref:`Vector3f`& position) 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). .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - position - Position of the sound in the scene .. rubric:: See also: :ref:`getPosition ` .. index:: pair: function; setRelativeToListener .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a81ee0bc1c3e4b4348e6a7a791f31fb4b: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setRelativeToListener(bool relative) 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). .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - relative - True to set the position relative, false to set it absolute .. rubric:: See also: :ref:`isRelativeToListener ` .. index:: pair: function; setMinDistance .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1acf61df2388f55cbc759d112c389e84af: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setMinDistance(float distance) 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. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - distance - New minimum distance of the sound .. rubric:: See also: :ref:`getMinDistance `, :ref:`setAttenuation ` .. index:: pair: function; setAttenuation .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a90d1941023ac569193b269065d73de00: .. ref-code-block:: cpp :class: doxyrest-title-code-block void setAttenuation(float attenuation) 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. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - attenuation - New attenuation factor of the sound .. rubric:: See also: :ref:`getAttenuation `, :ref:`setMinDistance ` .. index:: pair: function; getPitch .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a6cd19d074c46b26801948c8d90cfb9f3: .. ref-code-block:: cpp :class: doxyrest-title-code-block float getPitch() const Get the pitch of the sound. .. rubric:: Returns: Pitch of the sound .. rubric:: See also: :ref:`setPitch ` .. index:: pair: function; getVolume .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1aca9cd53b4aa90f98fc5061ab7e57c93d: .. ref-code-block:: cpp :class: doxyrest-title-code-block float getVolume() const Get the volume of the sound. .. rubric:: Returns: Volume of the sound, in the range [0, 100] .. rubric:: See also: :ref:`setVolume ` .. index:: pair: function; getPosition .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a3e36d949b0a5cb869d3f02dde2651c32: .. ref-code-block:: cpp :class: doxyrest-title-code-block :ref:`Vector3f` getPosition() const Get the 3D position of the sound in the audio scene. .. rubric:: Returns: Position of the sound .. rubric:: See also: :ref:`setPosition ` .. index:: pair: function; isRelativeToListener .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1ad7a78ac0d348c767a0ee6f4058f95bc3: .. ref-code-block:: cpp :class: doxyrest-title-code-block bool isRelativeToListener() const Tell whether the sound's position is relative to the listener or is absolute. .. rubric:: Returns: True if the position is relative, false if it's absolute .. rubric:: See also: :ref:`setRelativeToListener ` .. index:: pair: function; getMinDistance .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a14d801b275c0fd45998fd249db937276: .. ref-code-block:: cpp :class: doxyrest-title-code-block float getMinDistance() const Get the minimum distance of the sound. .. rubric:: Returns: Minimum distance of the sound .. rubric:: See also: :ref:`setMinDistance `, :ref:`getAttenuation ` .. index:: pair: function; getAttenuation .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1a23012b8face222ffac3500715de69e20: .. ref-code-block:: cpp :class: doxyrest-title-code-block float getAttenuation() const Get the attenuation factor of the sound. .. rubric:: Returns: Attenuation factor of the sound .. rubric:: See also: :ref:`setAttenuation `, :ref:`getMinDistance ` .. index:: pair: function; operator= .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1aa4e8e5e469eca903896981c09242a1fa: .. ref-code-block:: cpp :class: doxyrest-title-code-block SoundSource& operator=(const SoundSource& right) Overload of assignment operator. .. rubric:: Parameters: .. list-table:: :widths: 20 80 * - right - Instance to assign .. rubric:: Returns: Reference to self .. index:: pair: function; play .. _doxid-class_e_e_1_1_audio_1_1_sound_source_1aa944f65970d35222ea1a99229f09ea34: .. ref-code-block:: cpp :class: doxyrest-title-code-block virtual void play() = 0 Start or resume playing the sound source.
