Kimmo thank you, very good feature. The common impulse and frequency window is an excellent idea, clear, fast, missing in some measuring systems.

^Thanks!

Manual in English updated for rev. 2.0.5.0 (refresh if needed). German translation has been delayed for few months due to continuous changes. Maybe it's good time to update that too.

I can add support also for other than ARTA pir and CLIO mls files, if specification for binary file format is available. I'll leave searching, asking/begging and investigations to users who need to convert other IR formats to frequency responses.
Generally, I'm hoping that adequate FFT features would be available in measurement programs. External tools and add-ons need (free) work and using is extra step in design procedure.

Wow, very nice.

I particularly like the real time update of the frequency response while the cursors in the impulse response are being adjusted. This is great for seeing the effect of reflections in the impulse response and avoiding them.

I did have a strange issue where choosing FFT length 4096 or 8192 was causing a large shift in the signal level in the FR window relative to other FFT length choices, but after opening a few different files I'm not able to reproduce it again.

Most probable reason is that 4096 and 8192 were shorter than total length of time window. Manual adjustment of FFT length is possible after window adjustments are done but shortening of automatic selection has some risks.
Automatic selection is possible to lock, but that would prevent user to increase accuracy/resolution at low frequencies. Limiting of shortest possible FFT length would be more sophisticated and user friendly.

This is done to the latest build a minute ago.

If an active filter has a bypass button, it will better displays a change.

^Could you tell me where you don't see a change?
If you mean Invert bypass [B] button in version 1.1, that inverts bypass status of all blocks in selected way. No problem to create and set up filter chain which does not change transfer function when bypass statuses are inverted.

Please download and install the latest build of rev 2.0.5.1 (2018-10-06) to get all new and modified features listed in changelog:

* Reading of txt/frd/zma files changed more flexible to allow empty lines, comments between data rows, scientific notation and comma as field separator.

Conversion IR to FR
* Added magnitude scaling.
* Added 'Info header' checkbox. Writes metadata to output files.
* Added support for drag&drop.

I am trying VituixCAD now in Wine on Linux.

I just used the manual on the website.
I only have two major issues;

1 - moving parts is extremely slow when the grid is on (when grid is turned off it works fine)
2 - if I go to options I get a error "InvalidArgument=Value of '-1' is not valid for 'index'

This is the log file;

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
