    Our sincere apologies. The macOS build was up to date but the windows build was not.

    We’ve just rebuilt Windows and verified the version. Please download 3.1.2 again.

    2.1.0 accidentally included a new file loader which is not fully tested. We have turned this off in 2.1.1 which is now available.

    Thanks for your help.

    We were able to replicate the problem and version 2.1.1 is now available.

    Thanks for your help.

    Hi Vilcans,

    There was a minor file format change in 2.1.0 but older files should load. Could you please send the System and (channel) project files to info@eclipaseaudio.com

    Hi Vilcans,

    We’re very sorry to hear this. We need some more information to replicate the problem.
    What version are you using?
    What sample rates do you have set for the channels?
    Are you on any particular tab (in the workflow) when the crash occurs?
    What other windows are open? (e.g. second view, aux responses)

    If you have any work already saved to system and (channel) project files, please email them all to info@eclipseaudio.com.

    Noted. Thanks. Is there a technical reason why this would be helpful? Or just educational? From your example, the phase looks clean and there doesn’t seem to be a loudspeaker measurement loaded on the Import tab.

    Hi Kohno,

    Is this an electrical/digital measurement of the filter in a processor? Or an acoustic measurement of the filter applied to a loudspeaker?

    The amount of pre-ringing in the filter depends on how filter filter is designed and what your goals are (e.g. phase linearisation).

    Reply to this post then email the FIR Creator project and/or filter to our support address and we’ll take a look.

    Best regards,

    Hi Kamil,

    We suspect the LIR is a complementary crossover where one channel is IIR filtered (e.g. HPF) and the other channel (with a LPF response) is created from the difference between the original input (with some small delay) and the filtered signal. When the two channels are added back together, only bulk delay is present and there isn’t any frequency varying phase shift.

    We’ve been asked previously about implementing complementary crossovers in FIR Designer M and it’s on the todo list. To match LR’s LIR, we need to check with LR as to exactly what IIR filters they are using. Their paper suggests a 4th order IIR (for the HPF) and in our limited experience with this method, it results in approximately a 2nd order response on the complementary channel.

    Hi Stefano,

    It’s all there in the table on https://eclipseaudio.com/

    Specific to making a FIR filter, the key difference is that FIR Designer doesn’t have any limits on the number of prototype Mag and Phase filters you can use and on the number of frequency bands or regions in the Auto Mag and Auto Phase tabs.

    Also, FIR Designer has integrated measurement averaging and a few workflow helpers like Second View, Impedance viewing and no limits on the number of simultaneous project windows visible at any one time.

    Maybe take a look at the FIR Designer 3 Overview video on

    If IIR data from REW is exported as “filter settings,” then we (EA) need to either get the exact math from REW or take the time to match REW to known equations for IIR filters.

    If IIR data from REW is exported as “filter coefficients,” then we could add the capability to load in the raw coefficients, but those IIR filters would not be editable or adjustable in FIR Designer. And the user would need to ensure the sample rates between REW and FIR Designer matched.

    Hi spada,

    From the Export tab, FIR filters can be exported as text files and copied into the FIR Filter block or loaded using the Load button.
    https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/filters/firfilter

    The IIR tab of FIR Designer can export raw coefficients for all IIR filters to a summary txt file, and the raw coefficients can be entered in this block.

    Noted. We would need to implement a “REW” IIR mode since many processors and software have unique interpretations of Q or BW.

    WAV file import problems are common from REW since the IR peak is often well into the WAV file, rather than near the start. Better to use the IR TXT export. See REW on https://eclipseaudio.com/loudspeaker-measurements/
