lores~ implements an inexpensive lowpass with an adjustment that lets you add a specified resonance. The middle inlet sets a kind of cutoff frequency, but the sharpness of the filter depends on the resonance passed in through the right inlet (0 is a little bit sharp and 1 as sharp as possible).
A number sets the initial cutoff frequency. The default value is 0. If a signal is connected to the inlet, the argument corresponding to the inlet is ignored.

Common Box Attributes
In middle inlet: Sets the lowpass filter cutoff frequency.
In right inlet: Sets a "resonance factor" between 0 (minimum resonance) and 1 (maximum resonance). Values very close to 1 may produce clipping with certain types of input signals.
The filtered input signal. The equation of the filter is
yn = scale * xn - c1 * yn-1 + c2 * yn-2
where scale, c1, and c2 are parameters calculated from the cutoff frequency and resonance factor.
