Aurora for Audacity Beta, first release of 5 plugins for Audacity

I managed to replicate the error, entering 20,0 and 20000,0 as frequency limits, instead of 20.0 and 20000.0
Please note, my system is English, so the decimal separator is a dot, not a comma. Using a comma causes the error...
Can this be your problem?

If not try employing EXACTLY all the parameters as shown here:

Yes.
Sti is available in the Linux version...

Yes.
The Audacity developer team asked me to remove from free distribution the version of Audacity 2.0.0, which was "matched" with the Aurora plugins, as we did enable ASIO support when compiling it.
It appears, for reasons which I really do not understand, that it is forbidden to release the compiled version of Audacity with ASIO support enabled (albeit the open source code contains the ASIO code...).
I did not want to start an argument with the developer team, albeit I am 100% sure that it was perfectly lawful, here in Italy, to distribute the ASIO version (I have a written evaluation from the legal office of my University).
But, of course, users of Aurora need to employ the ASIO version of Aurora, so I did not remove it from my web ste, I simply protected it with an easy-to-guess password.
So, just guess, it's easy...

We are not going to drop the Audacity version, we are quite sure that the Audacity project is the future...
We have now just released the source code of our Aurora modules for Audacity on Google Code:

http://code.google.com/p/aurora-for-audacity/

This should answer to the request of accessing the modules from other programs...

Regarding the possible port of Aurora modules as general-purpose plugins (such as VST, Direct-X, CoreAudio, Ladspa, etc.).
Unfortunately these "formats" present severe limitations for the functionality of most of the Aurora modules. These "plugin" formats are designed for realtime audio processing, with small chunks of data being continuously sent and received between the host program and the plugin.
Instead the Aurora modules usually require to access the whole recording at once. This was possible in the old XFM plugins under CoolEdit and Adobe Audition, until Adobe stepped above Audition 3.0, disrupting the XFM API.
Currently, I am not aware of any other DAW capable of supporting external modules which are allowed to get full access to the opened waveforms, except for the "Modules" interface of Audacity. However, if you have info on another open-source or freeware software which can support external modules without the limitation of "normal" plugin formats, please tell me, we can consider to port the Aurora modules for such a DAW.

As a final remark: Audacity is a nice project, although of course its functionality is still quite primitive. The latest version of CoolEditPro 2.1, a.k.a. Audition 1,0, of 10 years ago, is still quite better than current Audacity 2.0.4. But the developer team is working hard for improving Audacity. I have good expectations, and I hope that we will finally reach and surpass the functionality of CoolEditPro 2.0 in one or two years. And that is what most people really needs, anything beyond that is mostly superfluous.
Under Windows (and OSX, thanks to PlayOnMac), I am still employing Audition 1.5. The subsequent versions 2.0 and 3.0 are, for me, already too much complex and totally not needed.

The new version of Aurora modules, compatible with Audacity 2.0.4 and 2.0.5 is now available for Windows.
You can download it here: www.aurora-plugins.com/Public/Aurora-for-Audacity/2.0.5/

The great new is that it also includes the STI (Speech Transmission Index) module...
