        No we haven’t.

        For FIR filters, their software does the crossover FIR filter design for you from measurements, unless you select “custom” – see section 2.2.2 of their documentation. They don’t provide any information about loading a “custom” filter, but it’s likely it’s just a TXT file of coefficients, which our software can export.

        For the IIR filter EQ, like I said above, we need to know the specific math they use so that we can make a “Four audio” IIR mode in our software. If you already have FourAudio products, I suggest you contact FourAudio and ask them to contact us. We’d be happy to implement their filters, but we need the math. See “IIR filter emulation” on https://eclipseaudio.com/brand-integration/

          Can I confirm if FIR Designer M is required for exporting filters to Lake / IPX?

          FIR Designer M can push settings to the Lake XP modules and the older Lake FIR 3-way module. FIR Designer can only push settings to the Lake FIR 3-way modules.

          Is it possible to sideload filters (with the re-windowing) to other platforms that don’t support DTP (like Linea Research) or can this only be done via DTP.

          You can make IIR+FIR presets for any/all brands. In the case of Linea Research, you’d create the channels for the preset in FIR Designer (or FIR Designer M) then manually copy the IIR filters to System Engineer and export the FIR filters to SFI files (for import into System Engineer).

          The DTP windows, for some specific brands, handle brand specific sanity checks and transmission. For example, the Lake DTP window talks over a network to the Lake Controller, the Powersoft DTP window does model checks and exports in Powersoft XML format, the Marani DTP window talks over a network directly to Marani processors…. etc. The sideloading (with rewindowing) is provided in the DTP windows specifically to enable bringing existing FIR filters into those platforms.

          If you already have a filter and want to change or rewindow it, start FIR Designer, don’t load any measurement on the import tab, load the existing filter on the Target tab, then use the workflow to design a new filter to match the Target. This will give an effectively identical result to the sideloading/rewindowing..

            FIR Designer only works with the original Lake FIR 3-way module. FIR Designer M works with the Lake FIR 3-way and the newer Lake XP modules (1,2,3 & 4-way).

            >> Is there any alternative workflow in FIR Designer to load FIR filters onto a 1-way module in Lake Controller?

            Sorry, no.

              4.6.5 is now available. Restart FIR Designer M, or select “Check for updates” in the menus.

                Exactly which version do you have? Are you on windows or macOS?

                Edit: We’ve found the issue and it’s Windows only. We’ll have a fix out shortly.

                  After some investigation, this is something we don’t have any control over. Stopping the signal generate stops measurement streaming. Then Smaart is resetting the streaming smoothing each time the stream is re-enabled. We’ll pass this on to Rational Acoustics for comment.

                    In this situation, setting the filter delay to greater than zero just adds bulk delay. It’s the same as adding channel delay (in a processor). If you find that you need to set the FIR filter delay to something – say 12 samples – and the filter samples (before the peak) are zero, then you could change the FIR filter delay to 0 and set the GPD tab delay to 12 samples.

                          You can already move your license to a new machine buy first deactivating on the old machine then installing and activating as usual on the new machine.

                            >> I’m using 16000 Taps with a 8000 Tap Delay with a 48kHz Measurement and FIR export.

                            I’m curious – what processor are you using that can run 16000 tap filters?

                            >> So, Group Delay is expected at 166,66 ms.

                            Yes, assuming you are designing linear-phase filters. Note, FIR Designer can design arbitrary phase filters where the group delay can vary.

                            >> But I can’t use greater values than 100 ms in the GD plot window. Is there any solution to evaluate GD with filter Delays >100 ms?

                            Noted. It’s an arbitrary limit on the line edit box. We’ll raise the limit in the next update.

                            >> Second question is in regards of a lifetime license as an upgrade to my actual annual license fee?

                            See https://eclipseaudio.com/upgrades/

                            We can provide you with a discount coupon, towards FIR Designer M (Perpetual), equivalent to the value of the remaining months on your current annual subscription. Note: with a perpetual license the features are frozen at the version you purchase (e.g. 4.6). If you would like to proceed, email us at info (at) our website and we will arrange the coupon. (Your subscription license will be disabled after upgrading.)

                              Never mind. We’ve found the problem in the Windows build. A fix will be out within 24 hours.
