highpass filter

This is a first-order IIR (infinite impulse response) highpass filter using biquad~. When you look inside you will see that it is made by subtracting a lowpass filtered version of a signal from the signal itself. The lowpass filter used is lpass1~, one of the simplest filters in the Jimmies collection (see lpass1~). The hpass1~ module accepts a cutoff frequency value which defines the frequency at which the low frequencies will begin to be attenuated; they will be attenuated right down to 0 Hz. There is no control for the slope of the attenuation curve (see hpass2~ for a second-order highpass filter).
