Function audioToWav

audioToWav(
    audioData: Float32Array<ArrayBufferLike>[],
    sampleRate: number,
    options?: Partial<WaveWriteOptions>,
): ArrayBuffer
Converts PCM audio data into a fully valid wave file.

The metadata uses the INFO chunk to write the information. It is encoded with utf-8.

Note
The audio is saved as PCM S16LE (signed 16-bit little-endian integers)

Warning
Do not call in audioWorkletGlobalScope as it uses TextEncoder for the metadata.
Parameters
- audioData: Float32Array<ArrayBufferLike>[]
  The PCM audio data. For stereo, pass [leftData, rightData].
- sampleRate: number
  The sample rate, in Hertz.
- options: Partial<WaveWriteOptions> = DEFAULT_WAV_WRITE_OPTIONS
  Additional options for writing the file.
Returns ArrayBuffer
The binary file.
