Ambisonic config files
Please find below Ambisonic decoders up to 5th Order for different loudspeaker configurations. The loudspeaker order goes from top to bottom and counter-clockwise. The config files can be used with compatible VST plugins that use the AMBIX format. The decode matrices are presented in ACN/SN3D format. You can download individual config files or cut to the chase and download all in a single zip file here. If you do not see your loudspeaker configuration listed here, then you should look at the excellent Ambisonic Toolbox which can be found here.
