How many FIR taps does FIRmaker need? What is the latency of FIRmaker processing?

Various simulations and experiments have been carried out by AFMG. So far results indicate that a minimum of 250 taps at 48 kHz is required in order to achieve good performance for the majority of use cases. A number of 500 to 1000 taps are recommended for complicated setups.

Processing of 250 FIR coefficients at 48 kHz corresponds to 5 ms of latency.
