Ambisonic config files
Please find below Ambisonic decoders up to 5th Order to support binauralisation with Subject data 003 through 020 of the SADIE binaural database. This is the same set of decoders as for Subjects 001 and 002 (the KEMAR and KU100 heads) but does not include the Order 2 Dodecahedron and Order 3 Sphere packing configurations. If you wish to use these virtual loudspeaker arrays then you will need to utilise the HRTFs from either Subject 001 or 002. 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.
