FIR Designer logo

Load in FIR Creator and FIR Designer on the Target tab

FIR Creator and FIR Designer can be used in “Direct Design” mode to create a filter with almost any desired magnitude and phase response. This response can then be used as the target response, when designing a FIR filter for a loudspeaker.

From “Direct Design” mode, export the response as a “FIR Designer target file” (.FDT). In the regular mode (i.e. “Direct Design” unchecked), on the Target tab select “File” or “Design + File” and load the FDT file under “Target File” using the “Load” button.
