MAYAFLUX_API std::vector< double > MayaFlux::zero_crossing_rate_per_channel	(	const std::vector< Kakshya::DataVariant > &	channels,
		size_t	window_size = 0
	)

Calculate zero crossing rate per channel for multi-channel data.

Parameters

channels	Vector of channel data
window_size	Analysis window size (0 = whole signal)

Returns

Vector of zero crossing rates, one per channel
