“Listening Twice”

In this listening session, we want to engage with ambisonics UHJ recordings from the seventies. UHJ, also called C-format, is a hierarchical system for encoding and decoding directional sound information within ambisonics technology. Although UHJ allows up to four channels, mostly only the 2-channel variant has been and is used, since this ensures full compatibility with 2-channel playback media (usually stereo records or CDs). With a special UHJ decoder, the three channels LRT (corresponding to W, X, Y) can be played back in Ambisonics as spatial audio. We want to compare the various playback options together by listening using various historical recordings.
