Constructor & Destructor Documentation

adm_rtconfig_t()

adm_rtconfig_t::adm_rtconfig_t	(	unsigned	nchannels_in,
		unsigned	nchannels_out,
		int	adaptation_ratio_,
		const std::vector< int > &	front_channels,
		const std::vector< int > &	rear_channels,
		const mha_real_t	fs,

		const int	decomb_order,
		const std::vector< mha_real_t > &	tau_beta,
		const std::vector< mha_real_t > &	mu_beta
	)

Construct new ADMs.

Used when configuration changes.

Parameters

nchannels_in	Number of input channels
nchannels_out	Number of output channels
adaptation_ratio_	Update beta every adaptation_ratio frames
front_channels	Parser's front_channels setting
rear_channels	Parser's front_channels setting
fs	Sampling rate / Hz
distances	Distances between microphones / m
lp_order	Filter order of FIR lowpass filter for adaptation
decomb_order	Filter order of FIR compensation filter (compensates for comb filter characteristic)
tau_beta	Time constants of the lowpass filter used for averaging the power of the output signal used for adaptation
mu_beta	Adaptation step sizes
