| Lookline is one of the partners of the new EU-funded research project SIPARIO, and they should build (and then commercialize) the 32-speakers spherical array. In one year, more or less. Our DIY 32-channels power amplifier weights 12 kg, including the 3U case with wheels and the Orion32 USB interface. I did ship it by aircraft to UK for the demo during the AES-62 Conference: www.angelofarina.it/Public/AES-62/QUOTE (Danrues @ 10/3/2020, 18:14) If Lf parameter beyond 1kHz is unreliable with a typical dodecahedron, whats with all the data (populating books and papers) that was obtained -probably- with a standard 12-faced sound source? Almost ALL acoustical parameters are unreliable above 1 kHz if the source is not omnidirectional... C50, C80, D50, ts, STI, EDT, IACC, etc... Only T20 is robust enough. And yes, most published data are based on unreliable measurement setups. |
