Signals

  • finished ( )

Fires when the audio stops playing.

Member Variables

  • int area_mask - Areas in which this sound plays.
  • float attenuation_filter_cutoff_hz - Dampens audio above this frequency, in Hz.
  • float attenuation_filter_db - Amount how much the filter affects the loudness, in dB.
  • int attenuation_model - Decides if audio should get quieter with distance linearly, quadratically or logarithmically.
  • bool autoplay - If true audio plays when added to scene tree. Default value: false.
  • String bus - Bus on which this audio is playing.
  • int doppler_tracking - Decides in which step the Doppler effect should be calculated.
  • float emission_angle_degrees - The angle in which the audio reaches cameras undampened.
  • bool emission_angle_enabled - If true the audio should be dampened according to the direction of the sound.
  • float 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 - Sets the absolute maximum of the soundlevel, in dB.
  • float max_distance - Sets the distance from which the ‘out_of_range_mode’ takes effect. Has no effect if set to 0.
  • int out_of_range_mode - Decides if audio should pause when source is outside of ‘max_distance’ range.
  • bool playing - If true, audio is playing.
  • AudioStream stream - The AudioStream object to be played.
  • float unit_db - Base sound level unaffected by dampening, in dB.
  • float unit_size - Factor for the attenuation effect.

Numeric Constants

  • 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.
  • 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.
  • 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.

Member Function Description

  • float get_playback_position ( )

Returns the position in the AudioStream.

  • void play ( float from_position=0.0 )

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

  • void seek ( float to_position )

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

  • void stop ( )

Stops the audio.
