      Yes. FIR filters can push a non-minimum phase response to whatever you like. The result will be your desired mag & phase + some bulk delay.

        The final length depends on your measurement and exactly what filtering is needed to achieve your goals. Just try it in FIR Creator EX. On the Export tab you can adjust the filter length and delay to where the filter is working the way you want, and you can see the result applied to your loudspeaker measurement. If you’re unsure how to use the workflow, take a look at the videos and tutorials on https://eclipseaudio.com/fir-filter-design-tutorial/.

          It really depends how low in frequency you’d like to go – at least a few 1000’s taps at 48 kHz.

          Take a look at Section 8 on the page

            When using FIR Designer M for multi-way, how you use the “Find peak” depends on how you took the measurements.

            If your measurement system delay was locked when taking measurements across all the drivers, the relative delay between drivers is in the measurements, and using “Find peak” on each measurement will loose the relative delay. In this situation, you could complete your design, put all the processing into your DSP then re-measure and tune the channel delays. Alternatively, use “Find peak” on one of the drivers – say the HF – and manually apply the same delay (on the “Import tab”) to the other drivers. In this way the relative delay between drivers (in the measurements) is not lost. You can complete your design and you won’t need to re-measure and tune delays.

            If your measurement system delay was not locked when taking the measurements across all the drivers, then it doesn’t matter if you use “Find Peak” or not. You will still have to re-measure and tune the relative driver delays anyway.

            “Find peak” it’s useful for taking out any high phase slope, which is the consequence of delay in the measurement, before working on designing the processing.

            I’d also suggest looking at the “FIR DESIGNER M (Multi-way) | Overview” video on https://eclipseaudio.com/fir-filter-design-tutorial/

              More issues were reported in 4.0.5 and we’ve just released 4.0.6.

              Thanks for your patience.

                >> I had 2.6.11 installed and I did an update install on top of that.
                >> Can I remove this install and reinstall 4.0.4?

                You can reinstall 2.6.11 and it will replace 4.0.4.

                However, we’ve just released 4.0.5 which should address the problem you’ve described. Unfortunately changes in then underlying GUI toolkit – not our code – caused a long list of problems with the UI, including tabs missing and menu problems.

                Let us know if 4.0.5 is working.

                  The copying should be possible. We’ll take a look and get back to you.

                    Are you on macOS or Windows?

                    If on macOS,
                    – are you using the ARM or Intel version?
                    – are you copying the app from the DMG into the Applications folder and running it from there? (There can be licensing issues if running the app directly from within the DMG file.)

                    If on Windows, what Windows version do you have?

                    If you reinstall 2.6.11, does the app, including the licensing, work as normal?

                    Could you email us the files from the old system you’re trying to load?

                        Hi acmcool,

                        A few questions:
                        – What versions of SMAART and FIR Designer M are you using? (Which SMAART 9 product?)
                        – In SMAART, in Options->API, is the API set to enabled and have you subsequently restarted SMAART?
                        – Is your macbook air connected to a Wifi network when running both SMAART and FIR Designer M?

                        Best,

                            I’ve looked over your system and in the IIR filters, there may be too many biquads. (I parametric = 1 biquad. For HPF’s and LPF’s, each order 2 = 1 biquad; so a 4th order HPF = 2 biquads.) The Lake API has a comment that hardware limits the number of biquads, shared across all channels, to 37. Your system has.

                            Channel 1 = 12
                            Channel 2 = 14
                            Channel 3 = 12
                            Total = 38

                            Maybe remove a few filters and see if the “invalid parameter” error goes away. We don’t access to our Lab Gruppen test hardware for about a week, so we can’t test your system until next week.

                              Hi Helge,

                              >> Also, is there a way of making the LM behave as a 2 in/6 out with the FIR module from Eclipse?
                              >> I got an error message when I tried to load the open module in module B saying I had to load it in module A.
                              >> It loads in module A setting up LM26 as a 1 in/3 out processor.

                              I don’t know specifically about the LM26 but on the original PLM amplifiers (not the PLM+), a FIR 3-way replaces two classic modules, and so must be loaded into module A. These PLM’s cannot run XP modules and cannot run two FIR 3-way modules, and from what you describe I suspect your LM26 is similar.

                              >> I tested FIR Designer M with Lake LM26 last night.
                              >> I have successfully loaded all 3 outputs in my design LM26 by loading them one at a time from a new, empty project.

                              Sorry, I’m a bit confused. FIR Designer M pushes all channels, and input IIR’s, to the Lake module at once. How are you loading them into the LM26 one at a time?

                              >> Lake Controller error code 2.
                              >> A invalid parameter was provided.

                              The Lake FIR 3-way has specific sample rate requirements. The input IIR’s run at 96 kHz. The output channels can be any combination of 12 and 24 kHz OR uniquely 12,24 & 48 kHz (in any order). These samples rates can be set on the FIR Designer M “Setup” tab. Even if no input IIR’s are used in your design, the input sample rate must be set to 96 kHz.

                              If none of this helps, email us the system (FDS) and channel (FDP) files, and we’ll take a look.
