Sorry, no. Apple keep moving forward quickly with their OS releases and the GUI toolkit we subscribe to – Qt – moves with it.

EA Support31 August 2023 at 2:33 pm #696The data across the formats is effectively identical, with some caveats for WAV.
CSV(row) has FIR coefficients formatted as text in a row.
0.0010, -0.07, 1.0, 0.03 …..CSV(column) has FIR coefficients formatted as text in a column
0.0010,
-0.07,
1.0,
0.03
…WAV uses 24 bit WAV files to store the coefficients. WAV does quantize the data to 24 bit depth, but still has an effective range of > 130 dB. WAV also clips coefficients that are > 1.0 or < -1.0. But “FIR Creator EX” will give a warning if your FIR filter coefficients are outside -1.0 to 1.0 and you are trying to save as WAV.
I’d recommend using one of the CSV formats.

EA Support26 August 2023 at 7:13 am #693Yes. FIR filters can push a non-minimum phase response to whatever you like. The result will be your desired mag & phase + some bulk delay.

EA Support23 August 2023 at 8:01 am #690The 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/.

EA Support22 August 2023 at 9:54 pm #688It 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

EA Support11 August 2023 at 8:20 am #681When 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/

Thanks for your patience.

4 August 2023 at 1:29 pm #678>> 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.

EA Support2 August 2023 at 9:52 pm #671Are 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?

10 July 2023 at 11:40 am #666Hi 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,
EA Support18 April 2023 at 9:34 pm #651I’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 = 38Maybe 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.
Best regards,
