      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.

                  Is there a question?

                    >> I will have a new MacBook in a couple of days, so I need to transfer license to that new hardware anyhow, right?

                    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?

                      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.

                              Since you will need to set 96 kHz delay in the miniDSP for the tweeter channel, uncheck “FIR output sample rate” on both channels and change the sample rates on the Setup tab to 96 kHz.

                              >> Also I’m sending you the FDS file by email so you can see how I’ve set up all the changes we’ve discussed so far.

                              The “FIR Phase Adjust” tab for the Tweeter has the 2nd filter (near 19 kHz) boosting. Change this to a cut, to meet the upper plot phase.

                              Also, on the Export tab for the Woofer channel, on the middle plot, check “Show FIR filtered loudspeaker” and notice how the response below about 300 Hz doesn’t closely match the ideal filter (before windowing to a filter length of 1700 samples). You could try using IIR filters to help in this frequency region; assuming your miniDSP can also load IIR filters.

                                Quarter sample delay is only available on the Import tab for import alignment purposes in the design process. Quarter sample delay is not available on the G/P/D tab because processors implement whole (integer) sample delay. Processors cannot do delay by fractions of a sample.

                                  7 November 2025 at 12:51 pm #501174

                                  Use the + – buttons to move the delay by 0.25 of a sample.

                                  >> Also I don’t understand why in import tab delay is negative number

                                  The -4.25 samples is on both channels, so their time relationship is retained. Moving both negative in time just gets their phase into a range that is easier to work. (This delay is not important for the miniDSP.)

                                  >> while in gain/polarity/delay tab it is positive number.

                                  The positive sample delay on the gain/polarity/delay tab is delay ONLY on the tweeter. It moves the tweeter phase to better match the woofer phase in frequency region of the crossover filter. This delay is added with the “FIR alignment delay” to give the “Total Processor Delay” — see the system Export tab. The “Total Processor Delay” is the delay that needs to be set on each channel in the miniDSP, to ensure your overall design works. On the example I gave you, channel 1 – the tweeter – needs 7.3958 ms and the woofer 0 ms. But these numbers may be different since you have changes the channels to 96 kHz and likely adjust the FIR filter sizes.
