biquad_bandpass() [2/2]

MAYAFLUX_API void MayaFlux::Kinesis::Discrete::biquad_bandpass	(	double	frequency,
		double	q,
		double	sample_rate,
		std::vector< double > &	a,
		std::vector< double > &	b
	)

Second-order bandpass coefficients, constant 0 dB peak gain.

Parameters

frequency	Centre frequency in Hz, clamped to (0, sample_rate/2)
q	Quality factor; higher is narrower
sample_rate	Sampling rate in Hz
a	Denominator output, resized to 3, a[0] == 1.0
b	Numerator output, resized to 3

    b.assign({ biquad.b0, biquad.b1, biquad.b2 });
