ambiX v0.2 – Ambisonic plug-in suite

ambiX screenshot ReaperI am happy to finally release my cross-platform Ambisonic processors useable as VST/LV2 plug-ins or standalone application under Windows, Mac OSX and Linux. They can be used in flexible hosts like Reaper, Ardour MaxMSP or as standalone applications with Jack.

The plug-ins can be used to produce 3D Ambisonic content or do post production on recordings. (eg. Soundfield or Eigenmike microphone recordings)
The Ambisonic order is variable and can be choosen at compile time. A practical limitation for Reaper is 7th order due to the 64 channel limit. The processors use the ambiX convention (full 3D, ACN channel ordering, SN3D normalization)

You may want to use these plug-ins in combination with the mcfx multichannel effect plug-in suite: http://www.matthiaskronlachner.com/?p=1910

mcfx v0.2 – multichannel audio plug-in suite

mcfx_meter32mcfx is a suite of multichannel VST plug-ins for MacOS, Windows and Linux
(mcfx_delay, mcfx_filter, mcfx_gain_delay, mcfx_meter)

these plug-ins are very handy if you want to process multiple channels in one go for example
* multiple loudspeaker setups, Ambisonics (see ambiX)
* Microphone array post productions (eg. Eigenmike)
….

currently high channel counts per track are only possible with the DAWs Reaper (Win, OSX) and Ardour (Linux, OSX)

- channel count is configurable with compile time flag
- cross plattform VST for MacOSX, Windows and Linux
- uses the JUCE framework (www.juce.com)
- ready to use binaries for MacOSX (≥ 10.6, 32/64 bit) and Windows (32/64 bit)

Source code: https://github.com/kronihias/mcfx

Binaries: (4, 8, 16, 24, 32, 36, 64 channel version)

table top – binaural recording

playing table top in the observatorytable top is a live performance by Matthias Kronlachner created for the loudspeaker sphere in the Astronomical Observatory tower of Vilnius University.
The performance was recorded on November 22nd, 2013 and December 3rd, 2013.

The original format of the piece is 5th order 3D Ambisonics, but you can listen to a binaural mixdown here: (please listen with high quality headphones!)

LAC 2013 – Ambisonics plug-in suite for production and performance usage

ambix_encoderToday i held my presentation about the ambix Ambisonics audio plug-ins at the Linux Audio Conference in Graz. This plug-in suite features cross-plattform Ambisonics tools for converting between different channel sequences and normalization schemes, encoding up to 7th order, rotating Ambisonics signals and binaural decoding with various virtual loudspeaker configurations in different venues.

The software has to be polished and will be released hopefully soon.

In the meantime you may have a look at the
paper ] or [ slides ].
