Track 5 of the album was stereo, so it was processed with UHJ-SuperStereo/II
UHJ-SuperStereo is a part of the UHJ decoding process that allows normal stereo material to be manipulated into a quasi-UHJ signal that can be processed into B-Format, which enables the decoder to give a simulated ambisonc decode.
