21 January 2023 at 6:15 am #613Ok, we have replicated here what you are seeing and there’s definitely a problem. We don’t know if the problem is in our Lake plugin or in more recent versions of the Lake Controller. We’ll investigate this week.
Thanks for you patience,

21 January 2023 at 5:12 am #612>> Is it normal, that I cannot access the output filters of your FIR modul in the Lake Controller?
No, that’s not normal.
In the project file you sent through, you’re using the “Legacy (General)” IIR mode. Change this to “Lake” and set your HPF in the Lake mode.
The plugin screen-shot shows “Data Set” “Yes” for “Out 3”, but “-” for Sample Rate and the number of biquads. This is a clue that data is not going through. (We will look into that here.)
I’d suggest:
– Run FIR Designer and open two extra windows using menu “Project” -> “New Window”
– Set each window to a “Design Sample Rate” of 48 kHz, 24 kHz and 12 kHz respectively.
– In each window, set a different parametric filter in the “Lake” IIR mode and set the FIR filter length to 384 samples
– Open the Lake DTP window “Export to Lake FIR 3-way module,” connect to the module then
— In “Use FIR Designer Window” select the 12 kHz window and press push “Delay, IIR + FIR” to “Out 1”
— In “Use FIR Designer Window” select the 24 kHz window and press push “Delay, IIR + FIR” to “Out 2”
— In “Use FIR Designer Window” select the 48 kHz window and press push “Delay, IIR + FIR” to “Out 3”If this is successful, the “Sample Rate” and “Biquads” column should show numbers for the output channels, and not show “-“.
Let me know how you go.

20 January 2023 at 10:39 pm #610Your project file has the FIR filter set for 96 kHz. The Lake FIR 3-way module only allows 48 kHz, 24 kHz and 12 kHz for module output channels.
Uncheck “FIR output sample rate.” This will change the FIR sample rate back to 48 kHz. (When we implemented “FIR output sample rate” as separate to the processing sample rate, we forgot to add an error message for Lake.)

14 January 2023 at 6:15 am #607It can be done one window at a time. It’s just easier with 4 windows open.

13 January 2023 at 9:39 pm #605Thanks. And did you have 4 FIR Designer windows open – one for input IIRs and one each for the 3 module output channels? Email us the FIR Designer project FDP files and we’ll take a look.

13 January 2023 at 9:59 am #603Hi URI,
Which product (FIR Designer, FIR Designer M) and which product version are you using?
Which Lake module are you using? (The Lake FIR 3-way – that comes with our Lake plugin – or one of the Lake XP modules?)
Can you email us your FIR Designer project and/or system files? info (at) eclipseaudio.com
Also, can you provide a screenshot of the FIR Designer Lake DTP or “Export to Lake” window?Best regards,
EA Support
9 December 2022 at 11:51 am #598I just emailed you a link to the plugin.
Note that FIR Creator EX and FIR Designer work with the Lake FIR 3-way module. Th newer Lake XP 1, 2, 3 and 4-way modules, with FIR, can only be loaded from FIR Designer M.

19 November 2022 at 7:32 pm #594My apologies. 2.6.1 includes support for importing CLIO IR txt files so we have just uploaded a 2.6.1 dmg.
Best regards,
EA Support
19 November 2022 at 4:19 pm #593As per the notes, 2.6.1 is an update for MS Windows only. The adjacent 2.6.0 dmg link for mac is provided to save time scrolling further down the page; if upgrading from 2.5.x or lower.

12 November 2022 at 7:23 am #588This morning we wrote an importer specifically for this CLIO time format. It will be available in the next release.

>> Thanks a lotHi,
Our 3+ column TXT import by default assumes freq|mag|phase|coherence.
We do some checking of the file for specific formats that can be inferred from header or comment text, but without any headers or comments, we assume freq|mag|phase|coherence.
>> Many software export with a 3rd imaginary column
I have never seen anything like this before, but since the header text is
Time[s] Real[V] Imag[V]
we could write a customer importer for this. I’ve added this to the TODO list but I can’t say when it will be ready.Best regards,

2 November 2022 at 6:44 pm #583Hi Weiguo,
>> Is there anyway to convert this response file using FIR Creator EX?
No.
>> I don’t know how to change it to 0 dB.
You don’t need to have the measurement at around 0 dB. The “Import” tab has the gain adjustment for exactly this purpose.
I have taken a look at your FDP file. Here are a few suggested minor adjustments:
– On the “Mag Adjust” tab, change the gain of the “High Shelf” to -7.9 dB.
– On the “Auto Mag” tab, change the “Min Freq” to 90 Hz.>> I imported a speaker response and created a fir file. But the result seems hardly doing anything.
From what is shown on the “Export” tab, the FIR filter should definitely be audible.
All I can suggest is checking that the processor is importing the file and that the filter is enabled. What processors are you using and what FIR filter format did you export?
Best,

1 November 2022 at 7:08 pm #581Regarding the -108.1 dB gain, with “Normalise magnitude to max” checked, the Import tab looks for the peak in the measurement and shifts the response so that the peak is at 0 dB. The FIR Creator workflow needs the response to be around 0 dB. (Maybe your measurement magnitude response has units of dB SPL and your mic was close to the loudspeaker.)
Regarding your FIR filter, provide a screenshot of the Export tab and a link to you project *.fdp file.

20 October 2022 at 2:48 pm #576Crown itechHD’s require a specific number of coefficients. The last we checked, it was 897, but it might have changed. You may need to try different files with different numbers of coefficients until it works.If you still can’t get it to work, I suggest contacting Crown. They may have a problem with the FIR loading.
Regarding precision, your 2nd screenshot shows that the coefficients do match. It’s just that the iTech display is rounding/truncating at 6 decimal places, which equates to approximate -120 dB relative to full scale; so I think you’ll find the trunction doesn’t matter.
