In my experience pre-ringing is fairly subjective, and it’s audibility can depending on frequency range and listening ability. Some people claim to hear pre-ringing more clearly over headphones than through loudspeakers.

The linear-phase brick-wall crossovers in some commercial speaker processors, and available in our software, have visible pre-ringing but are generally considered inaudible.

Regarding your design, if you’re concerned, try setting up a blind listening test both with your loudspeakers and maybe over good quality headphones.

In the globcon software, go to Help -> Documentation and search for CSV. It has a section “CSV File Format” which states the CSV file must be text with 2 columns – the first column frequency and second column magnitude – and with the the first line “FREQUENCY,MAGNITUDE”. “NOTE: CSV files to be imported in Custom EQ currently cannot contain any phase information; only magnitude curves are valid. Import of complex custom filters with phase information might be implemented in the future.” You can make these files yourself for testing.

Our products can import responses as CSV files or TXT files in freq|mag, freq|mag|phase or freq|mag|phase|coherence and use them as the basis for the filter design. Our products can also export FIR filters as CSV and TXT, but these are a single column of coefficient values. On eclipseaudio.com, see the “Import|Export” menu for more details.

We’d love to collaborate with DirectOut and we spoken with them on a few occasions, including at InfoComm. If you have contacts and can nudge them along, we’d be very appreciative.

With ‘FIR Designer M’, the desired crossover responses can be included in the per-channel target responses, in which case the Auto IIR will push towards the crossover target. However IIR filters tend to minimum-phase, so, depending on what type of crossover target you are using, the result of the Auto IIR might have the desired crossover magnitude but not the desired phase.

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.

Regards,
EA Support

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)

EA Support

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.

Best regards,

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.
