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.

enum OutOfRangeMode:

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.

Description

Plays a sound effect with directed sound effects, dampens with distance if needed, generates effect of hearable position in space.

Audio streams

Property Descriptions

area_mask

Setter	set_area_mask(value)
Getter	get_area_mask()

Areas in which this sound plays.

float attenuation_filter_cutoff_hz

Setter	set_attenuation_filter_cutoff_hz(value)
Getter	get_attenuation_filter_cutoff_hz()

Dampens audio above this frequency, in Hz.

attenuation_filter_db

Setter	set_attenuation_filter_db(value)
Getter	get_attenuation_filter_db()

AttenuationModel attenuation_model

Setter	set_attenuation_model(value)
Getter	get_attenuation_model()

Decides if audio should get quieter with distance linearly, quadratically or logarithmically.

autoplay

Setter	set_autoplay(value)
Getter	is_autoplay_enabled()

If , audio plays when added to scene tree. Default value: .

String bus

Bus on which this audio is playing.

doppler_tracking

Setter	set_doppler_tracking(value)
Getter	get_doppler_tracking()

Decides in which step the Doppler effect should be calculated.

float emission_angle_degrees

Setter	set_emission_angle(value)
Getter	get_emission_angle()

The angle in which the audio reaches cameras undampened.

Setter	set_emission_angle_enabled(value)
Getter	is_emission_angle_enabled()

If , the audio should be dampened according to the direction of the sound.

emission_angle_filter_attenuation_db

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

Setter	set_max_db(value)
Getter	get_max_db()

Sets the absolute maximum of the soundlevel, in dB.

max_distance

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

pitch_scale

Setter	set_pitch_scale(value)
Getter	get_pitch_scale()

Changes the pitch and the tempo of the audio.

bool playing

Getter

is_playing()

If , audio is playing.

stream

Setter	set_stream(value)
Getter	get_stream()

The AudioStream object to be played.

stream_paused

Setter	set_stream_paused(value)
Getter	get_stream_paused()

float unit_db

Setter	set_unit_db(value)
Getter	get_unit_db()

Base sound level unaffected by dampening, in dB.

unit_size

Setter	set_unit_size(value)
Getter	get_unit_size()

Factor for the attenuation effect.

Method Descriptions

float get_playback_position ( )

Returns the position in the .

void play ( from_position=0.0 )

Plays the audio from the given position ‘from_position’, in seconds.

Sets the position from which audio will be played, in seconds.

void stop ( )

Stops the audio.
