Thank you for this outstanding plug in!!Hi, thanks for reply - you make me very happy!
Additional names for the filters such as their db/octave or "Linkwitz-Riley" etc"Linkwitz-Riley" identical to "Classic" filter. I named it to "classic", because it draws by another formula at logarithmic scale and parametrized by another concept. I don`t like db/octave regulator, because it reflect physical realization with discrete steps.
A dual ms/distance scale for the delayYes, i think about this.
* A version of delay adjust for when multiple subs are used and they are not equidistant to the main speakers/listener.In first versions i made a support of second sub with independent delay and volume, but remove it later. Two reasons: it make using of plugin harder and no one use it. I plan to make independent plugin for this at future, if anybody need it. You can use Matrix Mixer (or some another) yet.
* In addition, I understand this is mono signal for the sub channel, could it be made into stereo?
If I unsync L/R there will be some influence on the total cross over frequency/timing curve. I guess this influences phase?
Unsync mode is just simple equalization, no other side-effects.
The adjustable FIR lengths, which I assume is the same as "filter taps" (please correct me if I misunderstand) enables a balance between resource usage, the time it takes to process and quality. If I set it to max, the 700 ms, I assume this will render the highest resolution in the bass. Is this correct?
No, more taps no make higher resolution, it needs only for "brickwall" filtering and some peoples who like big taps. 700 ms = 32768 taps at 44.1 kHz samplerate. For example, the impulse response of "Soft" filter at 100Hz with width=2:
