27 March 2025 at 7:14 am #1012Hi Eddi,
‘Phase only’ on import: We’ve added that to the todo list.
Two measurement paths – separate magnitude and phase: It’s unlikely we’ll implement this but you can achieve this in the following way.
– Create your measurement as a 3 column TXT or CSV file (freq Hz, mag dB, phase deg) with the mag and phase from your separate measurements
– Load this measurement on the Import tab
– Do all your desired magnitude manipulation on the Mag Adjust and Auto Mag tabs, and make sure ALL the filters are set to ‘Linear phase’
– Do all your desired phase adjustments on the Phase Adjust and Auto Phase tabs
The result at the Voicing tab is the combination of the above, and you can then voice to taste.Keyboard keys for filter dB, Q and frequency: We’ll consider it.
Regarding the binaural measurements, are you request we add measurement capability into our software? We have considered this but many people are very particular about the measurement tools they use – Klippel, SMAART, SysTune, SoundCheck, REW, etc. – so to date, we haven’t ventured into this space.
Regarding the ‘AVG + phase from one ear’, it sounds like you would like an additional “Averaging Mode” called “Power (using Ref. phase)”. With this, the phase from the measurement denoted as the ‘Reference’ would be used. We’ll consider this.

24 March 2025 at 6:53 am #1006We are considering releasing a direct conversion tool, however you can get an almost identical result with our tools by loading an EV FIR filter on the channel target tab. The workflow is described in this post:
With this approach you can also create the new FIR filters at different sample rates. And, ensure the effective filter delay (ms) is the same as the old filters, so that you don’t introduce timing differences between old and new platforms.
>> Will FIR Designer-M accomplish this?
Yes, as above. Make sure the system target is turned off before working in the channel workflow. FIR Designer (single channel) can also do this, but with FIR Designer M you get the ability to design and simulate full multi-way designs.

26 February 2025 at 8:22 am #1001We have looked through the FIR Designer M multi-band limiter code in depth and can’t see any problems. However one idea comes to mind.
The three bands of the multi-band limiter are, by default, un-muted. If multi-band limiter crossovers have not yet been set, then all three bands will be passing audio and summing. This equates to 9.54 dB of gain.
Try muting all but one band. This should bring the gain back to 0 dB.

25 February 2025 at 9:21 pm #999Hi LB,
We don’t currently have any Lake products set up here to test, so it will take some time. In the meantime, try setting the Lake Controller in Designer mode (in User Preferences), then for the XP module, go to “IO Config and Worksheets” “Levels” tab, and scroll vertically through the table. Various settings, including for the MBL, are displayed.
What version of the Lake Controller are you using?

2 February 2025 at 11:26 am #991Yes, the filter length is the number of samples or taps. And yes, the delay allows you to move the peak within the filter length. The delay represents the time=0 point in the filter and is the effective bulk processing delay through the filter. The delay is not needed for SigmaStudio.
Please read the FIR filter guide to learn more.

18 January 2025 at 4:01 pm #988You can check these yourself by loading them into the Import tab.
FIRLR2 sample1_1.bin & FIRLR2 sample1_3.bin are the HF (channel 3)
FIRLR2 sample1_2.bin is the MF (channel 2)>> Probably there is some bug in your software.
We just checked the export for each channel here and it’s working correctly.

16 January 2025 at 6:48 am #983Do any of the Averaging options take into consideration the Coherence of the Transfer Function measurements in use?
No, the coherence is not used. However, incorporating coherence in the averaging process is on the TODO to investigate and implement.

16 January 2025 at 6:44 am #982Our support is focussed specifically on using our products. We don’t have the resources to provide individual assistance, advice, training & education in DSP fundamentals, concepts & best practices and loudspeaker measurement techniques. Other forum members may be able to help, otherwise I suggest you seek other sources of information on measurement techniques and best practices.

14 January 2025 at 3:32 pm #978Is it possible to import the original manufacturer’s driver SPL and impedance curves into Eclipse, given that these are typically provided in PDF, JPEG, or PNG formats?
Curves from images? No. Impedance can be loaded into the Import tab, but it must be TXT file with 2 columns – Frequency and Impedance.
Alternatively, is there any converter software available to transform these curves into a format compatible with FIR design tools?
I’ve heard there are some tools around. Best try a Google search.
Note that driver manufacturer’s SPL measurements, unless specifically described, are typically made in an infinite baffle wall. The driver response will not be the same as in your cabinet.

14 January 2025 at 7:00 am #976Hello, I tried to make LR2 linear phase from your sample file(System2 3way LF MF brickwall) you send me before. But unfortunately magnitude and phase is not very flat as you can see in the screen shot attached. Can you help me to see what I’m doing wrong?
Attached I’m sending project file.
Best Regards!
We’ll send a modified file back to you. Open your original file and the new file in separate FIR Designer M windows and study the differences. The primary difference is that you had all the “FIR Auto Mag” tabs set to minimum phase, not linear phase. We made some other adjustments on various tabs also.

14 January 2025 at 6:40 am #975To import FIR filters into MiniDSP Flex, use the “Binary file (32 bit, float)” format from FIR Designer. This will save as a “.bin” file.
Also see:
https://docs.minidsp.com/product-manuals/flex/dsp-reference/fir-filtering.html>> into miniDSP Flex Eight directly as one of Presets?
In miniDSP Flex, FIR filters can be loaded individually onto channels, within the currently selected preset. For more information on Flex presets, you will need to read the miniDSP documentation.

12 January 2025 at 9:07 pm #973Thank you. Now I succeed to import mls files. But I have problem with design of crossovers which is designed in VituixCAD by another person. I can’t find some blocks like LP1, BEQ in your list. Attached you can see details about the crossover I want to design. Could you help me to design such crossover in your software. Measurement files of that speaker are files which I sent you in previous emails. It seems to me very complicated. I studied your tutorials , but still I’m not able to design my first crossover in Eclipse.
LP1 sounds like Low-pass 1st order. In our software, choose a butterworth low-pass and set the order to 1.
I’m guessing BEQ is just a parametric filter.Regarding your analog circuit block diagram,
– the tweeter has two HP2 (high pass 2nd order) filter blocks which combine to be a 4th order high pass.
– the midrange effective has a 4th order low-pass, a 4th order high-pass and one parametric
– and the woofer effective has a 7th order low-pass, one parametric and a LEQ (which I don’t know). I think this 7th order is a mistake. It’s probably supposed to be a 4th order low-pass and a 3rd order high-pass.Regarding your target diagram,
– the tweeter appears to have a 4th order linkwitz-riley high-pass
– the midrange appears to have a 4th order linkwitz-riley high-pass and a 4th order linkwitz-riley low-pass
– the woofer appears to have a 4th order linkwitz-riley low-pass and maybe a 3rd order high-pass.In FIR Designer M you can use the IIR filters tab to implement all of these filters, and see the summed response. Choose “HPF LR” and “LPF LR” – both 4th order – and “HPF Butter” set to 3rd order.
Regarding your measurement files, they don’t appear to be useful; they are way too chaotic in both magnitude and phase. I suggest you go back to whoever made the measurements for you and have them redone. If they still look like this, maybe have someone experienced check the measurement equipment and measurement setup.

12 January 2025 at 6:15 am #972Thank you for the MLS files. We are investigating now.

9 January 2025 at 5:15 am #970Can you please email us some of the exported Klippel files? The email address is info at our domain, or send us a message through the contact form on https://eclipseaudio.com/contact/ and we’ll reply from that address.
Did this appear with 4.3.14 (which we released overnight)? Did you experience this with the previous 4.3.13?
