40th AES Conference - Tokyo, 8-10 October 2010

The Verdi Projekt: Soundfield

As the Soundfield decode did perform poorly, an additional session was organized, asking to skilled Ambisonics users to provide their decodes:

Decoding method Score

A1 - Wiggins-HRTF 3 sufficient

A2 - Wiggins-VIEN 3 sufficient

A3 - Farina-Ambiophonics 3.5 poor

A4 - mac Caba 2.5 almost good

A6 – Dalenback 2.5 almost good

A7 - Rhonda Wilson 2.0 good

A8 - Williams MMA 1.0 very good
