Inherits: AudioStream < Resource < RefCounted < Object
Stores audio data loaded from WAV files.
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.

Format FORMAT_8_BITS =
8-bit audio codec.
Format FORMAT_16_BITS =
16-bit audio codec.
Format FORMAT_IMA_ADPCM =
Audio is compressed using IMA ADPCM.
LoopMode LOOP_DISABLED =
Audio does not loop.
LoopMode LOOP_FORWARD =
Audio loops the data between loop_begin and loop_end, playing forward only.
LoopMode LOOP_PINGPONG =
Audio loops the data between loop_begin and loop_end, playing back and forth.
LoopMode LOOP_BACKWARD =
Audio loops the data between loop_begin and loop_end, playing backward only.
PackedByteArray data =
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 =
Audio format. See Format constants for values.
int 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 =
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 =
The loop mode. This information will be imported automatically from the WAV file if present. See LoopMode constants for values.
int 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
According to the Nyquist-Shannon sampling theorem, there is no quality difference to human hearing when going past 40,000 Hz (since most humans can only hear up to ~20,000 Hz, often less). If you are using lower-pitched sounds such as voices, lower sample rates such as
22050 may be usable with no loss in quality.
bool stereo =
true, audio is stereo.
Error save_to_wav ( String path )
Saves the AudioStreamWAV as a WAV file to
path. Samples with IMA ADPCM format can't be saved.
.wav extension is automatically appended to
path if it is missing.
