      Hi Mark,

      We don’t prefer any particular method over the others. The multiple methods are provided in case one method struggles with a particular spectrum.

      Each method various in whether they use the power spectrum or log (dB) spectrum, and how they place each filter’s centre frequency.

      We do recommend smoothing to 3rd or 6th octave (in the Auto IIR window) before it places filters, otherwise the calculation will use way too many filters.

        Glad you found the latest version. (The issue was in the QT toolkit and was fixed quite some time back.)

          Hi,

          Sorry to hear this. This is first crash report we’ve had in a while.

          Re 1.
          – What ASIO buffer size are you using? I suggest something larger than 512 samples at 48 kHz.
          – Can you try a different audio interface? We’ve done most testing with RME interfaces and their drivers are very stable and well maintained. We’ve also used MOTU and a few others.

          Re 2. Can you record a video clearly showing the UI prior to and as it crashes? There may be clues in exactly what stage the UI is at before the crash.

          Re 3. I can’t explain this but it’s likely related to the audio interface issues.

            Sorry to hear this. We’ll need some more information. If you have a particular system file you’re using at the time the crashes happen, please email it to us.

            How many channels are you using?
            What are the sample rates of the channels?
            What IIR mode are you using?
            Do you have any input position IIR filters enabled?
            Is 2nd view open?
            What tab or window are you working on when it crashes?
            Are you using the IIR reference editor? (IIR mode converter)

              No, LIR is not yet in any of our products and we are still trying to get information from Linea Research.

                Thank you for describing the problem. A few versions back, we had a “Preferences” option to allow input filters for 1 channel systems, but we took this out without realising that it would cause problems for XP1 modules. We will definitely add this Preference option back in a future update.

                  We removed the help files over a year ago. We found it much more effective to provide help via the tutorials/videos section of the website and this forum.

                    We’ve just released version 4.3.7 to address this. Restart FIR Designer M and click the update link.

                      No, but it can be implemented. What’s the use case? (I’m not aware of any processor that converts frequency|mag|phase representation into a FIR filter, instead of loading coefficients directly.)

                          We’ve just released version 4.3.6 which retains the GPD delay but still calculates FIR Alignment delay.

                          Just restart FIR Designer M and it will give you a link to the new version.

                            FIR Designer 4.3.3 now includes Audio Weaver IIR filter export.

                                Hello again,
                                The FIR filter will work, however as the IIR biquads are not exactly in the format that audioweaver will like it will be quite impractical to work with this export. In the beginning of this email thread you said that you could add the required export format to audioweaver quite easily. Is there any chance you can add IIR export to audioweaver without any further modifications?

                                It’s on the worklist and will be in the next FIR Designer release, but I can’t give an exact timeframe. Maybe a few weeks.

                                Regards,
                                EA Support

                                  Hi, sounds great. Can you send me example files for IIR and FIR exports and I can check the compatibility with audioweaver. exports can for instance be a very simple notch filter with high q at eg 1kHz at 192kHz. or something that is esy to check the response with.

                                  IIR filter coefficients. (1 kHz parametric) As I mentioned, you will have to reformat this into the Audio Weaver IIR format.

                                  IIR Mode: Generic

Sample Rate: 192000 Hz

BAND_PASS, 1000.000 Hz, BW 0.100 (Q 14.424), -18.000 dB
b0:0.9972142660601733 b1:-1.9925586940177016 b2:0.9964118404059917
a0:1.0000000000000000 a1:-1.9925586940177016 a2:0.9936261064661650

                                  FIR filter coefficients. (8 kHz parametric @ 192 kHz)
