MAYAFLUX_API std::vector< double > MayaFlux::detect_onsets	(	const std::vector< double > &	data,
		double	sample_rate = 48000.0,
		double	threshold = 0.1
	)

Detect onset times in single-channel signal.

Parameters

data	Input signal data
sample_rate	Sample rate for time calculation (default: 48000 Hz)
threshold	Energy threshold for onset detection (default: 0.1)

Returns

Vector of onset times in seconds
