def is_silence(pcm_bytes, threshold=500, min_silence_ratio=0.95)

Detects if the given PCM16 byte buffer is mostly silence. Arguments:

Name	Type	Description
`pcm_bytes`	bytes	PCM16LE audio data.
`threshold`	int	Max absolute value to consider as silence.
`min_silence_ratio`	float	Minimum ratio of silent samples to consider the buffer as silence.

Returns:

Name	Description
`bool`	True if buffer is mostly silence, False otherwise.

def pcm16_to_wav_bytes(pcm_bytes: bytes,
                       num_channels: int = 1,
                       sample_rate: int = 24000) -> bytes

Convert PCM-16 audio data to WAV format bytes. Arguments:

Name	Type	Description
`pcm_bytes`	bytes	Raw PCM-16 audio data
`num_channels`	int	Number of audio channels (default: 1)
`sample_rate`	int	Sample rate in Hz (default: 24000)

Returns:

Name	Description
`bytes`	WAV format audio data

def make_object_serializable(obj: Any) -> Any
