Since Wideband here is a class of a FIR filter. > Maybe something like "wideband-fir" or "fir-wideband" would work better? Not sure FIR is even useful. That's just a particular filter architecture, not related directly to the characteristics userspace cares about. You can sometimes at least build a very similar response from an IIR filter. The sinc ones describe the pattern they let through, FIR isn't that specific.
