New Aurora for Audacity v. 2.3.3, With ASIO support

A minimal version of Aurora for Audacity has been recompiled for version 2.3.3 (Windows only, at the moment).
You can download it here:
www.angelofarina.it/Public/Aurora-for-Audacity/2.3.3+ASIO/

Here the instructions for installing it:
1) Install the standard Audacity 2.3.3 program, launching audacity-win-2.3.3.exe
2) Setup properly Audacity, setting the standard sampling frequency to 48 kHz, the Export Mode
to multichannel (disabling the crap default Downmix to Stereo option), installing additional libraries and plugins, etc.
3) Unzip the Audacity-2.3.3-asio.zip file to a temporary folder.
4) Copy all the files and folders in the same folder where the official Audacity 2.3.3 was installed
(usually C:\Program Files (x86)\Audacity), overwriting the existing files with the same name.

At this point launching audacity.exe should show the ASIO option, if
any ASIO device driver is installed (install ASIO4ALL if you do not have
a sound card already equipped with ASIO driver).

The version of Aurora included is minimal, containing just three modules:
- Generate / Aurora Sine Sweep Generator
- Analyze / Aurora Acoustical Parameters
- Tools / Aurora Convolver

The other Aurora modules will be added in the next future.

The site is online. Try with this direct link, including the "HTTP":

It appears to be a bug of Forumfree, which does not add automatically the HTTP...
Instead it adds an HTTPS, which of course is wrong.

This is a known bug of Audacity. It does not support 4-channels tracks, hence an Ambisonics recording should contain 4 mono tracks.
But the first two channels are erroneously "packed" in a two-channels stereo track.
However, it is quite easy to "split" it in two mono tracks.
Just click on "Audio Track", and in the resulting drop-down list choose "split stereo to mono":


After doing that you can use the Aurora Convolver for getting your 4-channels impulse response, dragging the 4 recorded mono channels to "audio data", the inverse sweep to "filters", and selecting the flag "one for all":

Full Autorange determines which channel is louder, and rescales all the channels with the same gain, so that no clipping occurs on the loudest one. But the inter-channel gain differences are preserved.

We have now a stable release of Audacity 2.4.1 with Aurora plugins. Download it here, both for Windows and Mac:
