VDP and DBAP is based on the same idea, but DBAP as presented in the ICMC 2009 paper http://www.trondlossius.no/system/fileattachments/30/original/icmc2009-dbap.pdf has a number of additional features. The important difference of DBAP and ViMiC as compared to ambisonics and VBAP is that there are no restrictions on the positioning of loudspeakers or listener. Loudspeakers are not restricted to a ring/sphere surrounding the listener, but could e.g. be laid out as a regular or irregular grid in the space. This is what makes it useful for installations in one or more spaces, such as art galleries and museums, where rings and spheres of speakers might be impractical and the audience is free and expected to move about.
I really don't understand "...ambisonics and VBAP is that there are no restrictions on the positioning of loudspeakers or listener.", at least as regards to VBAP. We are currently - and have been for over two years now - using VBAP in The Morning Line sculpture (http://www.worldarchitecturenews.com/index.php?fuseaction=wanappln.projectview&upload_id=14039) and the reason we used it rather than Ambisonics was because it could cope with extremely irregular arrays of speakers. Comments?
