<brief_description>
Stores audio data loaded from WAV files.
</brief_description>
<description>
AudioStreamSample 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.

<description>
Saves the AudioStreamSample as a WAV file to [code]path[/code]. Samples with IMA ADPCM format can't be saved.
[b]Note:[/b] A [code].wav[/code] extension is automatically appended to [code]path[/code] if it is missing.
