FIR-CAPABLE PRODUCTS
FIR filter speaker implementation requires an amplifier or processor that support FIR filters. Here’s a list of products & the software they use to load the filters. The required FIR Creator, FIR Creator EX, FIR Designer and FIR Designer M export file format is also specified.
The list is not exhaustive and may have inaccuracies. Please contact us if you have products or more detailed information to add to this list.
For selected brands, data can be transferred via Direct-To-Processor functionality. Learn more.
Load in FIR Creator, Creator EX, FIR Designer & Designer M on the Target tab
FIR Creator, Creator EX & 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.
Export File Format: FIR Designer target file
Load using Intelli-Ware
Intelli series processors.
Export File Format: Text file (Column, decimal)
Tesira processors
Export File Format: CSV file (row)
Load using HiQnet Audio Architect or HiQnet London Architect
Export File Format: CSV file (Column, decimal)
Rename extension to FIT before loading into NetControl
Export File Format: Text file (Column, decimal)
Load using IRIS-Net
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.
Only in FIR Creator EX, FIR Designer 2 & FIR Designer M
Export File Format: GFK file (EV, Dynacord)
Load using the Lake Controller with the FIR Designer Lake Controller plugin
The Lake FIR 3-way V2 module which has 37 biquads and 384 FIR taps on each output channel. The input IIR’s run at 96 kHz and the output channels at 12, 24 or 48 kHz.
