AudioStreamPlayer3D¶

Plays positional sound in 3D space.

Descripción¶

Plays a sound effect with directed sound effects, dampens with distance if needed, generates effect of hearable position in space. For greater realism, a low-pass filter is automatically applied to distant sounds. This can be disabled by setting attenuation_filter_cutoff_hz to 20500.

By default, audio is heard from the camera position. This can be changed by adding a Listener node to the scene and enabling it by calling Listener.make_current on it.

See also AudioStreamPlayer to play a sound non-positionally.

Note: Hiding an AudioStreamPlayer3D node does not disable its audio output. To temporarily disable an AudioStreamPlayer3D's audio output, set unit_db to a very low value like -100 (which isn't audible to human hearing).

Enumeraciones¶

enum AttenuationModel:

ATTENUATION_INVERSE_DISTANCE = 0 --- Amortiguación lineal de la sonido según la distancia.
ATTENUATION_INVERSE_SQUARE_DISTANCE = 1 --- Amortiguación cuadrada del sonido según la distancia.
ATTENUATION_LOGARITHMIC = 2 --- Amortiguación logarítmica del sonido según la distancia.
ATTENUATION_DISABLED = 3 --- No dampening of loudness according to distance. The sound will still be heard positionally, unlike an AudioStreamPlayer. ATTENUATION_DISABLED can be combined with a max_distance value greater than 0.0 to achieve linear attenuation clamped to a sphere of a defined size.

enum OutOfRangeMode:

OUT_OF_RANGE_MIX = 0 --- Mix this audio in, even when it's out of range. This increases CPU usage, but keeps the sound playing at the correct position if the camera leaves and enters the AudioStreamPlayer3D's max_distance radius.
OUT_OF_RANGE_PAUSE = 1 --- Pause this audio when it gets out of range. This decreases CPU usage, but will cause the sound to restart if the camera leaves and enters the AudioStreamPlayer3D's max_distance radius.

enum DopplerTracking:

DOPPLER_TRACKING_DISABLED = 0 --- Desactiva el rastreo doppler.
DOPPLER_TRACKING_IDLE_STEP = 1 --- Executes doppler tracking in idle step (every rendered frame).
DOPPLER_TRACKING_PHYSICS_STEP = 2 --- Executes doppler tracking in physics step (every simulated physics frame).

Descripciones de Propiedades¶

int area_mask

Default	`1`
Setter	set_area_mask(value)
Getter	get_area_mask()

Áreas en las que se reproduce este sonido.

float attenuation_filter_cutoff_hz

Default	`5000.0`
Setter	set_attenuation_filter_cutoff_hz(value)
Getter	get_attenuation_filter_cutoff_hz()

Dampens audio using a low-pass filter above this frequency, in Hz. To disable the dampening effect entirely, set this to 20500 as this frequency is above the human hearing limit.

float attenuation_filter_db

Default	`-24.0`
Setter	set_attenuation_filter_db(value)
Getter	get_attenuation_filter_db()

Amount how much the filter affects the loudness, in decibels.

AttenuationModel attenuation_model

Default	`0`
Setter	set_attenuation_model(value)
Getter	get_attenuation_model()

Decide si el audio debe ser más silencioso con la distancia lineal, cuadrática, logarítmica, o no ser afectado por la distancia, desactivando efectivamente la atenuación.

bool autoplay

Default	`false`
Setter	set_autoplay(value)
Getter	is_autoplay_enabled()

If true, audio plays when the AudioStreamPlayer3D node is added to scene tree.

String bus

Default	`"Master"`
Setter	set_bus(value)
Getter	get_bus()

The bus on which this audio is playing.

DopplerTracking doppler_tracking

Default	`0`
Setter	set_doppler_tracking(value)
Getter	get_doppler_tracking()

Decides in which step the Doppler effect should be calculated.

Note: Only effective if the current Camera's Camera.doppler_tracking property is set to a value other than Camera.DOPPLER_TRACKING_DISABLED.

float emission_angle_degrees

Default	`45.0`
Setter	set_emission_angle(value)
Getter	get_emission_angle()

El ángulo en el que el audio llega a las cámaras sin amortiguar.

bool emission_angle_enabled

Default	`false`
Setter	set_emission_angle_enabled(value)
Getter	is_emission_angle_enabled()

Si true, el audio debe ser amortiguado de acuerdo a la dirección del sonido.

Default	`-12.0`
Setter	set_emission_angle_filter_attenuation_db(value)
Getter	get_emission_angle_filter_attenuation_db()

Dampens audio if camera is outside of emission_angle_degrees and emission_angle_enabled is set by this factor, in decibels.
