FIR Designer logo

FIR Designer target file

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.
