Detailed Description

Runtime configuration class for computing the exponentially averaged RMS of the channels of an input signal and storing it in an AC variable.

Constructor & Destructor Documentation

Get_rms_cfg()

Get_rms_cfg::Get_rms_cfg	(	mha_real_t	tau,
		Get_rms *	Get_rms,
		std::vector< mha_real_t >	rms_prev
	)

Constructor of the runtime configuration class.

Parameters

tau	Time constant for the exponential average / s
Get_rms	Pointer to the current instance of the plugin interface class
rms_prev	Vector of RMS values for each channel of the previous input signal fragment

Member Function Documentation

process()

mha_wave_t * Get_rms_cfg::process	(	mha_wave_t *	signal,
		Get_rms *	Get_rms,
		MHA_AC::waveform_t *	rms_ac
	)

Process function of the runtime configuration class (main signal processing function).

It leaves the input signal fragment unchanged; its purpose is to compute the AC variable rms_ac for further processing in the plugin chain

Parameters

signal	Pointer to the current input signal fragment
Get_rms	Pointer to the current instance of the plugin interface class
rms_ac	AC variable containing a pointer to the RMS values for each channel of the current input signal fragment

Returns

Pointer to the (unchanged) output signal fragment
