22 July 2024 at 5:17 am #867Hello 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-

19 July 2024 at 5:50 am #864Hi, 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.

19 July 2024 at 5:44 am #863Hello! I am interested in what is the difference between calculating the IIR filter method 1 and method 2?
The calculation method is the same. The differences are just text formatting. The OP asked about how to get coefficients through to Audio Weaver and the examples above are two of the IIR filter export formats we have in our products.

12 July 2024 at 7:02 pm #848The “InvM+T plot Zero Adjust (dB)” edit box has exactly the same effect as the slider, just without the convenience of the slider.
(Sorry, the slider was taking up too much space for it’s utility, so we’ve decided to remove it.)
Regards,
EA Support
12 July 2024 at 12:20 pm #844Thank you for noticing this. We intended to remove the slider in verion 4.3 but accidentally left it in place. To adjust the graph level, now use the “InvM+T plot Zero Adjust (dB)” edit box just to the left of the slider.
Best regards,

12 July 2024 at 12:11 pm #842In this situation reinstalling should work. If it doesn’t, then contact us through the form on the website or via email, and we can reset the license to ensure it does work.

10 July 2024 at 12:20 pm #839What I am looking for is using Eclipse Audio software to provide not just offline processing, but real-time measurement and processing too. As per the SMAART control example I referred to. Will your software ever be expanded to be able to make live measurements too?
This is reliant on REW providing a realtime measurement streaming capability. We have no control of this. I’d suggest putting the question to REW. In the case of SMAART, they have a well documented realtime streaming API, which we connect to.
<Optimised for what? what we hear? removing detrimental reflections? etc. Can you outline why their method is so useful and should be adopted by everyone? I’m not aware of their method being published, can you provide a reference to this literature please?>
For this, I refer to you to Rational Acoustics. Their online SMAART user guide discusses some of these topics as well as their smoothing strategies, MTW and MTW+.

7 June 2024 at 8:07 pm #832>> Is purchasing Smaart Modeler the only way to emulate MESA PEQ at this point?
Yes, but the settings need to be manually copied to the Lake Controller. Presently there’s no way to export settings from DM and import into the Lake Controller. (We are working with Lab Gruppen to address this.)
7 June 2024 at 7:35 pm #829>> CL or XP modules support both types of PEQ.
Yes, that’s correct, and so does the “Lake FIR 3-way” module. Every module has Mesa EQ on the front (which is PEQ1 in your screenshots), then IIR filters that are part of the core loudspeaker preset.
>> However, when loading speaker presets, most of the left type classic PEQ tabs disappear
>> and only the right type PEQ tabs (MESA EQ) are available in modules or groups.That’s because the loudspeaker manufacturer, who created the preset, has intentionally locked and hidden the IIR filtering (and delay, gain, polarity & crossovers) that form the core loudspeaker preset. They don’t want end-users adjusting the core preset, and so only the MESA EQ is available to users. For more details on how to lock and unlock modules, and how to hide and unhide EQ tabs, see the Lake Controller manual.
>> Therefore, most users only use the right type of PEQ (or MESA EQ).
Yes, and also because the this EQ is available in group EQ, which ultimately combines with the Mesa EQ for each loudspeaker module.
>> If Lake Mesa supports the right type of modeling in Smaart Modeler, I hope
>> your software can support it too. Is this possible?
>> Isn’t it possible to apply MESA EQ emulation at least to the IIR filter?As you have shown in your screenshots, the Lake Mesa filters are completely different to regular IIR parametric filters. It’s not possible to translate and exactly match a Lake Mesa EQ response with IIR filters, with the limited number of IIR filter biquads available in any of the Lake modules.
Like I said, in future we might provide Lake Mesa emulation in FIR Designer, but currently there is no easy way to send the Lake Mesa information to the module in the Lake Controller (along with all the other core preset information, including IIR filters, gain, polarity and delay).
