At our last speaker Gio Jacuzzi described how engineers use ambisonics, a full-sphere surround sound technique that can contain sound sources above and below the listener, to create a 3D audio experience. He went on to explain that audio engineers have created microphones called “binaural stereo microphones” that can replicate humans' three natural audio perception properties. To emulate our natural listening experiences, engineers place these microphones in artificial heads and ears to make recordings. This why we can experience a 3D audio sensation while listening to a recording made with binaural microphones over headphones.
After the talk Gio answered questions from the audience and the lively discussion continued over an apéro.
