API

encodeWavFileFromAudioBuffer (audioBuffer: AudioBuffer, wavFileType: WavFileType) : ArrayBuffer

• audioBuffer: An AudioBuffer that contains the audio data.
• wavFileType: WavFileType.int16 (0) for 16 bit signed integer, WavFileType.float32 (1) for 32 bit float.
• Return value: An ArrayBuffer that contains the raw data bytes of the generated WAV file.

encodeWavFileFromArrays (channelData: ArrayLike<number>[], sampleRate: number, wavFileType: WavFileType) : ArrayBuffer

• channelData: Arrays containing the audio samples (PCM data). One array per channel.
• sampleRate: Sample rate (samples per second).
• wavFileType: WavFileType.int16 (0) for 16 bit signed integer, WavFileType.float32 (1) for 32 bit float.
• Return value: An ArrayBuffer that contains the raw data bytes of the generated WAV file.
