AudioStreamPlayer3D
Inherits: Spatial < Node < Object
Plays 3D sound in 3D space.
Description
Plays a sound effect with directed sound effects, dampens with distance if needed, generates effect of hearable position in space.
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.

Enumerations
enum AttenuationModel:
- ATTENUATION_INVERSE_DISTANCE = 0 --- Linear dampening of loudness according to distance.
- ATTENUATION_INVERSE_SQUARE_DISTANCE = 1 --- Squared dampening of loudness according to distance.
- ATTENUATION_LOGARITHMIC = 2 --- Logarithmic dampening of loudness according to distance.
- ATTENUATION_DISABLED = 3 --- No dampening of loudness according to distance.
enum OutOfRangeMode:
- OUT_OF_RANGE_MIX = 0 --- Mix this audio in, even when it's out of range.
- OUT_OF_RANGE_PAUSE = 1 --- Pause this audio when it gets out of range.
enum DopplerTracking:
- DOPPLER_TRACKING_DISABLED = 0 --- Disables doppler tracking.
- DOPPLER_TRACKING_IDLE_STEP = 1 --- Executes doppler tracking in idle step.
- DOPPLER_TRACKING_PHYSICS_STEP = 2 --- Executes doppler tracking in physics step.
Property Descriptions
int area_mask
| Default | 1 |
| Setter | set_area_mask(value) |
| Getter | get_area_mask() |
Areas in which this sound plays.
float attenuation_filter_cutoff_hz
| Default | 5000.0 |
| Setter | set_attenuation_filter_cutoff_hz(value) |
| Getter | get_attenuation_filter_cutoff_hz() |
Dampens audio above this frequency, in Hz.
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 dB.
AttenuationModel attenuation_model
| Default | 0 |
| Setter | set_attenuation_model(value) |
| Getter | get_attenuation_model() |
Decides if audio should get quieter with distance linearly, quadratically, logarithmically, or not be affected by distance, effectively disabling attenuation.
bool autoplay
| Default | false |
| Setter | set_autoplay(value) |
| Getter | is_autoplay_enabled() |
If true, audio plays when added to scene tree.
String bus
| Default | "Master" |
| Setter | set_bus(value) |
| Getter | get_bus() |
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.
float emission_angle_degrees
| Default | 45.0 |
| Setter | set_emission_angle(value) |
| Getter | get_emission_angle() |
The angle in which the audio reaches cameras undampened.
bool emission_angle_enabled
| Default | false |
| Setter | set_emission_angle_enabled(value) |
| Getter | is_emission_angle_enabled() |
If true, the audio should be dampened according to the direction of the sound.
float emission_angle_filter_attenuation_db
| 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 dB.
float max_db
| Default | 3.0 |
| Setter | set_max_db(value) |
| Getter | get_max_db() |
Sets the absolute maximum of the soundlevel, in dB.
float max_distance
| Default | 0.0 |
| Setter | set_max_distance(value) |
| Getter | get_max_distance() |
Sets the distance from which the out_of_range_mode takes effect. Has no effect if set to 0.
OutOfRangeMode out_of_range_mode
| Default | 0 |
| Setter | set_out_of_range_mode(value) |
| Getter | get_out_of_range_mode() |
Decides if audio should pause when source is outside of max_distance range.
float pitch_scale
| Default | 1.0 |
| Setter | set_pitch_scale(value) |
| Getter | get_pitch_scale() |
The pitch and the tempo of the audio, as a multiplier of the audio sample's sample rate.
bool playing
| Default | false |
| Getter | is_playing() |
If true, audio is playing.
AudioStream stream
| Setter | set_stream(value) |
| Getter | get_stream() |
The AudioStream object to be played.
bool stream_paused
| Default | false |
| Setter | set_stream_paused(value) |
| Getter | get_stream_paused() |
If true, the playback is paused. You can resume it by setting stream_paused to false.
float unit_db
| Default | 0.0 |
| Setter | set_unit_db(value) |
| Getter | get_unit_db() |
Base sound level unaffected by dampening, in dB.
float unit_size
| Default | 1.0 |
| Setter | set_unit_size(value) |
| Getter | get_unit_size() |
Factor for the attenuation effect.
