      “Pause FIR Auto M & P Updating” intentionally pauses ALL calculations from Auto Mag through to export. It allows fast editing of IIR filtering, without being slowed down by the Auto Mag and Auto Phase calculations. Once you are happy with the IIR filters, uncheck “Pause FIR Auto M & P Updating” to continue your work.

        >> Unfortunately I can’t, voicing tab use channel target, not system target.

        True. But since the Voicing tab shows the combined response of all channels, and since the displayed Target is a combination of the system and channel Target, you can look change “edit” channels and get a good sense that the combined response meets your System target.

        >> Also System Export tab don’t have view for combined filtered IR and Step, which I think is useful

        We have considered this, but since each channel’s processing can have a different sample rate, it’s very complicated to calculate a combined IR and Step for the system. 2nd view does have a combined wavelet view.

            In “Preferences”, check “User per-channel plot checkboxes”. This allows each channel to have different plot display preferences on most tabs.

              Noted. We’ve added this to the TODO list.

              BTW you can compare the response to target on the voicing tab.

                Hi Eddi,

                Firstly, I should say we don’t advocate any particular EQ approach. We provide the tools to enable you to experiment with whatever approach you like and works for you. That said….

                We do suggest using the average of multiple measurements from a coverage area, and not a measurement from a single location. (In the car this might mean, for example, multiple measurements within ~30cm of the nominal head position for the front seats.) We also suggest fairly broad smoothing – e.g. 1/3rd or 1/6th octave – on the Auto Mag to avoid narrow, high-q boosts.

                Separate boost and cut parameters for the Auto Mag are under consideration and on the TODO list, but I can’t say when we might get to this.

                Best regards,

                  Hi Alex,

                  File import information is at

                  Loudspeaker Measurement Import File Formats

                  I presume you’re referring to text import so see the section “Text (*.txt) and CSV (*.csv)”.

                  Yes, if a file has only 2 columns – frequency (Hz) and magnitude (dB) – then a 3rd column of zeros needs to be added. This can be done in a text editor, Excel and maybe Apple Numbers or Google sheets. It’s on the todo list to provide for 2 column frequency and magnitude loading, but for now 2 column is interpreted as the time samples of an impulse response – column 1 are timestamps and column 2 is the sample value.

                    Before you send us any files, on the “Measurement Averaging” “Save” tab, for “Format: WAV file – Impulse Response…”, experiment with setting the “IR start (ms)” further negative before saving the file.

                    On the “Measurement Averaging” “Average” tab lower plot, look at the impulse response (by clicking on “IR Samples”) and you will likely see some of the impulse response extending negative. If so, then this needs to be saved in the WAV file to ensure the whole response – particularly at lower frequencies – is retained.

                    Setting “IR start (ms)” further negative effectively add bulk delay to the saved WAV file, but with anything other than minimum-phase responses, it’s the only way to retain the response accurately, since the response extends earlier in time than the IR peak.

                      Understood. It’s already on the TODO list but it’s not simple to implement in our codebase.

                        Please email* us a download link to the files you’re averaging, screenshots of the “Measurement Averaging” “Load & Setup” & “Averaging” tabs, and an “Averaging Session File” and we’ll take a look. I’m fairly sure I know what’s happening with the WAV export – there’s probably not enough samples being saved prior to the IR peak – but I need to confirm.

                        * info (at) our website.

                          From the product downloads page, download the “FIR_Designer_Lake_Plugin_3_2.zip” file and follow the instructions in the readme.txt file.
