MAYAFLUX_API std::vector< double > MayaFlux::extract_zero_crossing_regions	(	const std::vector< double > &	data,
		double	threshold,
		size_t	region_size
	)

Extract zero crossing regions from single-channel data.

Parameters

data	Input audio data
threshold	Minimum amplitude difference for zero crossing detection (default: 0.0)
region_size	Size of each region in samples (default: 1024)

Returns
