How bad is the “pre-ringing” of the FIR filters? Won’t this make the loudspeaker system sound bad?
FIRmaker does not generate linear phase filters. As such, the filters are not symmetrical in time about the peak of the filter’s impulse response. There is no requirement for the filters generated by FIRmaker to have pre-ringing. The transient behavior of the system will not be influenced.
