Python function

encode_wav_bytes

encode_wav_bytes()

max.serve.media.encode_wav_bytes(samples, sample_rate)

source

Encodes a float waveform as a 16-bit PCM WAV payload.

16-bit is what the format’s ubiquitous reader path expects and what every client can play; a generative model’s own noise floor sits well above the quantization step, so the width costs nothing audible.

Parameters:

• samples (ndarray[tuple[Any, ...], dtype[float32]]) – [channels, samples] float array with values in [-1, 1]. Values outside that range are clipped, which is what a decoder would do to them anyway.
• sample_rate (int) – Sample rate of the waveform, in hertz.

Returns:

The complete WAV file, header included.

Raises:

ValueError – If the waveform is not 2D, has no channels or no samples, or the sample rate is not positive.

Return type:

bytes
