At the 2008 demo I wrote about, other that the anomaly at the exact center, I thought it sounded pretty good. So did most of the 60 or so people who came though during the evening. Definitely not horrible. I played excerpts of some of my recordings that are on Ambisonia: Stravinsky's Pulcinella Suite, Beethoven's 4th Symphony and Appassionata Sonata, Dvorak Violin Concerto, Paul Doombusch's Hampi Bazzar, some of John Leonard's recordings, Jeffrey Silberman's too. There was a quite convincing sense of the space in which the recordings were made. In the Stravinsky recording, you hear the reverberation of the brass instruments moving around the hall, as it actually does. In the recording of the piano recital, you can hear a slight slap echo from the front of the balcony above and behind the microphone. The contrast from indoors to outdoors is especially striking. As I said earlier, the envelopment and accuracy of timbre are the keys for me -- they draw you into the performance. I would have been happy to play some HOA recordings, but I don't have any. > > the most striking experience of horizontal first-order degradation over > eight speakers was in the sala bianca in parma, using virtual ambisonic > speakers on their wfs system. fons demo'ed ambi rendering, and we switched > between six and eight sources.
