WebWindowed FIR filters use the cutoff frequency as part of the design process, but the cutoff is specified before the windowing operation. For Windowed FIR filters of sufficient taps (more than 10 for a simple lowpass), the cutoff frequency has a magnitude near 0.5 (or 6 dB down). This magnitude varies slightly with the order and the window type.
