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.

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.

We have received many questions about support for Lake processors. We are slowly working on a solution for loading FIR filters into the Lake FIR 3-way module, but have no idea when we will have something ready.
