Plays 3D sound in 3D space.
    public class AudioStreamPlayer3D : Spatial

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

Inheritance Chain


    public AudioStreamPlayer3D()


    "finished" ()

Fires when the audio stops playing.


    public int AreaMask { get; set; }

Areas in which this sound plays.

    public float AttenuationFilterCutoffHz { get; set; }

Dampens audio above this frequency, in Hz.

    public float AttenuationFilterDb { get; set; }

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

    public AttenuationModelEnum AttenuationModel { get; set; }

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

    public bool Autoplay { get; set; }

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

    public string Bus { get; set; }

Bus on which this audio is playing.

    public DopplerTrackingEnum DopplerTracking { get; set; }

Decides in which step the Doppler effect should be calculated.

    public float EmissionAngleDegrees { get; set; }

The angle in which the audio reaches cameras undampened.

    public bool EmissionAngleEnabled { get; set; }

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

    public float EmissionAngleFilterAttenuationDb { get; set; }

dampens audio if camera is outside of ‘emission_angle_degrees’ and ‘emission_angle_enabled’ is set by this factor, in dB.

    public float MaxDb { get; set; }

Sets the absolute maximum of the soundlevel, in dB.

    public float MaxDistance { get; set; }

Sets the distance from which the ‘out_of_range_mode’ takes effect. Has no effect if set to 0.

    public OutOfRangeModeEnum OutOfRangeMode { get; set; }

Decides if audio should pause when source is outside of ‘max_distance’ range.

    public float PitchScale { get; set; }

Changes the pitch and the tempo of the audio.

    public bool Playing { get; set; }

If true, audio is playing.

    public AudioStream Stream { get; set; }

The AudioStream object to be played.

    public bool StreamPaused { get; set; }

    public float UnitDb { get; set; }

Base sound level unaffected by dampening, in dB.

    public float UnitSize { get; set; }

Factor for the attenuation effect.
