AudioStreamWAV¶

Inherits: AudioStream < Resource < RefCounted < Object

Stores audio data loaded from WAV files.

Description¶

AudioStreamWAV stores sound samples loaded from WAV files. To play the stored sound, use an AudioStreamPlayer (for non-positional audio) or AudioStreamPlayer2D/AudioStreamPlayer3D (for positional audio). The sound can be looped.

This class can also be used to store dynamically-generated PCM audio data. See also AudioStreamGenerator for procedural audio generation.

Properties¶

PackedByteArray	data	`PackedByteArray()`
Format	format	`0`
int	loop_begin	`0`
int	loop_end	`0`
LoopMode	loop_mode	`0`
int	mix_rate	`44100`
bool	stereo	`false`

Methods¶

Enumerations¶

enum Format:

Format FORMAT_8_BITS = 0

8-bit audio codec.

Format FORMAT_16_BITS = 1

16-bit audio codec.

Format FORMAT_IMA_ADPCM = 2

Audio is compressed using IMA ADPCM.

enum LoopMode:

LoopMode LOOP_DISABLED = 0

Audio does not loop.

LoopMode LOOP_FORWARD = 1

Audio loops the data between loop_begin and loop_end, playing forward only.

LoopMode LOOP_PINGPONG = 2

Audio loops the data between loop_begin and loop_end, playing back and forth.

LoopMode LOOP_BACKWARD = 3

Audio loops the data between loop_begin and loop_end, playing backward only.

Property Descriptions¶

PackedByteArray data = PackedByteArray()

void set_data ( PackedByteArray value )
PackedByteArray get_data ( )

Contains the audio data in bytes.

Note: This property expects signed PCM8 data. To convert unsigned PCM8 to signed PCM8, subtract 128 from each byte.

Format format = 0

void set_format ( Format value )
Format get_format ( )

Audio format. See Format constants for values.

int loop_begin = 0

void set_loop_begin ( int value )
int get_loop_begin ( )

The loop start point (in number of samples, relative to the beginning of the sample). This information will be imported automatically from the WAV file if present.

int loop_end = 0

void set_loop_end ( int value )
int get_loop_end ( )

The loop end point (in number of samples, relative to the beginning of the sample). This information will be imported automatically from the WAV file if present.

LoopMode loop_mode = 0

void set_loop_mode ( LoopMode value )
LoopMode get_loop_mode ( )

The loop mode. This information will be imported automatically from the WAV file if present. See LoopMode constants for values.

int mix_rate = 44100

void set_mix_rate ( int value )
int get_mix_rate ( )

The sample rate for mixing this audio. Higher values require more storage space, but result in better quality.

In games, common sample rates in use are 11025, 16000
