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.

FIR Designer currently restricts the FIR filter length, for GKF files, to 513 taps to match the IRIS-Net maximum supported FIR filter length. The file format, however, allows for any length filter and FIR Designer may allow other lengths in the future.
