Functions
	lasp.filter.biquad.peaking (fs, f0, Q, gain)
	Design of peaking biquad filter.
	lasp.filter.biquad.notch (fs, f0, Q, gain=None)
	Notch filter, parameter gain not used.
	lasp.filter.biquad.lowpass (fs, f0, Q, gain=None)
	Second order low pass filter, parameter gain not used.
	lasp.filter.biquad.highpass (fs, f0, Q, gain=None)
	Second order high pass filter, parameter gain not used.
	lasp.filter.biquad.highshelf (fs, f0, Q, gain)
	High shelving filter.
	lasp.filter.biquad.lowshelf (fs, f0, Q, gain)
	Low shelving filter.
	lasp.filter.biquad.LP1compensator (fs, f0o, f0n)
	Shelving type filter that, when multiplied with a first-order low-pass filter, alters the response of that filter to a different first-order low-pass filter.
	lasp.filter.biquad.LP2compensator (fs, f0o, Qo, f0n, Qn)
	Shelving type filter that, when multiplied with a second-order low-pass filter, alters the response of that filter to a different second-order low-pass filter.
	lasp.filter.biquad.HP1compensator (fs, f0o, f0n)
	Shelving type filter that, when multiplied with a first-order high-pass filter, alters the response of that filter to a different first-order high-pass filter.
	lasp.filter.biquad.HP2compensator (fs, f0o, Qo, f0n, Qn)
	Shelving type filter that, when multiplied with a second-order high-pass filter, alters the response of that filter to a different second-order high-pass filter.
	lasp.filter.biquad.biquadTF (fs, freq, sos)
	Computes the transfer function of the biquad.
