1. A method for filtering sound signals with time-varying FIR filters, comprising performing with at least one processor, operations comprising:
obtaining or deriving a first parameter value based on a first location in a virtual space of a virtual sound source that moves in the virtual space between the first location and a second location;
obtaining or deriving a second parameter value based on the second location of the virtual sound source in the virtual space;
applying a first filtering operation using the first parameter value to a sound signal of the virtual sound source to produce a first filtered output;
applying a second filtering operation using the second parameter value to the sound signal of the virtual sound source to produce a second filtered output; and
removing artifacts due to movement of the virtual sound source from the first location to the second location by cross-fading between the first filtered output and the second filtered output.
