finished ( )

Emitted when the audio stops playing.

Enumerations

enum MixTarget:

MixTarget MIX_TARGET_STEREO = 0

The audio will be played only on the first channel.

MixTarget MIX_TARGET_SURROUND = 1

The audio will be played on all surround channels.

MixTarget MIX_TARGET_CENTER = 2

The audio will be played on the second channel, which is usually the center.

---

Property Descriptions

bool autoplay = false

• void set_autoplay ( bool value )

• bool is_autoplay_enabled ( )

If true, audio plays when added to scene tree.

---

StringName bus = &"Master"

• void set_bus ( StringName value )

• StringName get_bus ( )

Bus on which this audio is playing.

Note: When setting this property, keep in mind that no validation is performed to see if the given name matches an existing bus. This is because audio bus layouts might be loaded after this property is set. If this given name can't be resolved at runtime, it will fall back to "Master".

---

int max_polyphony = 1

• void set_max_polyphony ( int value )

• int get_max_polyphony ( )

The maximum number of sounds this node can play at the same time. Playing additional sounds after this value is reached will cut off the oldest sounds.

---

MixTarget mix_target = 0

• void set_mix_target ( MixTarget value )

• MixTarget get_mix_target ( )

If the audio configuration has more than two speakers, this sets the target channels. See MixTarget constants.

---

float pitch_scale = 1.0

• void set_pitch_scale ( float value )

• float get_pitch_scale ( )

The pitch and the tempo of the audio, as a multiplier of the audio sample's sample rate.

---

bool playing = false

• bool is_playing ( )

If true, audio is playing.

---

AudioStream stream

• void set_stream ( AudioStream value )

• AudioStream get_stream ( )

The AudioStream object to be played.

---

bool stream_paused = false

• void set_stream_paused ( bool value )

• bool get_stream_paused ( )

If true, the playback is paused. You can resume it by setting stream_paused to false.

---

float volume_db = 0.0

• void set_volume_db ( float value )

• float get_volume_db ( )

Volume of sound, in dB.

---

Method Descriptions

float get_playback_position ( )

Returns the position in the AudioStream in seconds.

---

AudioStreamPlayback get_stream_playback ( )

Returns the AudioStreamPlayback object associated with this AudioStreamPlayer.

---

bool has_stream_playback ( )

Returns whether the AudioStreamPlayer can return the AudioStreamPlayback object or not.

---

void play ( float from_position=0.0 )

Plays the audio from the given 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.
