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.
