In the app there is a ? button that gives you some small explanation about the different filters.
The explanations in the app are pretty much just fluff.
The slow roll-off filters cause aliasing, which means additional tones that aren't supposed to be there. You don't want to use either of the slow roll-off filters for maximum fidelity.
The short delay filters are minimum phase filters, which reduce latency at the expense of shifting the phase relationships of higher frequencies. Whether this is audible is debatable.
The symmetric filters are linear phase filters, which preserve the phase relationships at the expense of a slight increase in latency. I use the symmetric sharp roll-off filter as it is the one that preserves the original signal to the fullest extent.
