* ambix_vmic – same principle as directional loudness but will not output ambisonics signal but the selected part of the soundfield – similar to the virtual microphone approach * ambix_rotator – rotation around xyz axis * ambix_rotator_z – rotation around z axis * ambix_mirror – invert or mirror soundfield about x/y/z axis * ambix_maxre – apply or reciprocal apply spherical max_re weighting to suppress sidelobes according to Zotter, Frank – „All-Round Ambisonic Panning and Decoding“ * ambix_encoder – panning plug-in with different numbers of input channels – a width parameter spreads those channels equally along the azimuth * ambix_directional_loudness – amplify, attenuate or filter out certain parts of the spherical soundfielddf * ambix_converter – convert between different ambisonic standards on the fly (include different standards in one project), also between 2D/3D * MacOS: ~/Library/ambix/binaural_presets/ * Windows 7,8: C:\Users\username\AppData\Roaming\ambix\binaural_presets\ * presets for ambix_binaural (including impulse responses) and ambix_decoder are located in the folder ambix_binaural/Presets (or available as separate download) and should be copied in following folders
* ambix_decoder – same as binaural decoder but without the convolution, the loudspeaker signals are sent directly to the outputs (single band decoding) * ambix_binaural – binaural decoder with various loudspeaker setups in real world studios/venues > some information about the software can be found here:, This software package goes well together with the mcfx – multichannel cross plattform audio plug-in suite: > libzita-convolver3 optional for Linux (GPL v3) > This software uses the JUCE C++ framework, which is under GPL license. the practical maximum order is rather defined by the hosts maximum channel count (N+1)^2 or your CPU power > these plug-ins use a recursive implementation of the spherical harmonics, therefore the maximum Ambisonic order is defined at compile time.

> The plug-in suite use the ambiX *(1)* convention (ACN channel order, SN3D normalization, full periphony (3D)) except the sqrt(1/4pi) factor in equation 3. > cross-platform Ambisonic VST, LV2 plug-ins with variable order for use in Digital Audio Workstations like Reaper or Ardour or as Jack standalone applications. This software was developed during the work on my master thesis at the Institute of Electronic Music and Acoustic Graz. Read this article from the AES Design competition for some informations regarding the plug-ins!Ī slightly outdated paper about the plug-ins can be found here: Īmbisonic transformations are described here ICSA2014_KronlachnerZotter_AmbisonicTransformations.pdf For example with the Ambisonic Decoder Toolbox by Aaron Heller using Matlab/Octave.

Windows 7/8: C:\Users\username\AppData\Roaming\ambix\binaural_presets\Ĭurrently there is no preset generator included, you have to generate your decoding matrix with other tools.
(download includes decoder matrices + binaural loudspeaker impulse responses) You will also need the binaural decoder presets if you want to listen with headphones:

Mac OS X (>= 10.7) VST Universal Binaries: You may want to use these plug-ins in combination with the mcfx multichannel effect plug-in suite: The processors use the ambiX convention (full 3D, ACN channel ordering, SN3D normalization)Ī short video clip showing the plug-ins in action: A practical limitation for Reaper is 7th order due to the 64 channel limit. The Ambisonic order is variable and can be choosen at compile time.
Soundfield or Eigenmike® microphone recordings) The plug-ins can be used to produce 3D Ambisonic content or do post production on recordings. They can be used in flexible hosts like Reaper, Ardour, MaxMSP, Bidule or as standalone applications with Jack.

I 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.
