Some musings about getting more Ambisonics recordings to listen to. Work in progress.

Musings about scarcity by Jörn Nettingsmeier — last modified 2007-12-16 03:50

Is a scarce supply of arts and media really bad? My feelings about this are ambiguous...

AMBI@home - The search for extra-frontal intelligence by Jörn Nettingsmeier — last modified 2009-06-05 05:30

This paper describes the setup and calibration of a DoItYourself Ambisonic surround listening rig made from comparatively cheap components. The rig comprises a Linux audio workstation with JACK, Ardour2, AmbDec, and the JACE convolution engine. The DRC room correction software is used to compensate for room and speaker deficiencies. It is shown that a determined amateur can obtain very good results using only free software and commodity hardware in a standard domestic environment, and that dedicated Ambisonic playback systems based on such components might eventually be commercially feasible for a limited market of enthusiasts.

Shake, rattle and roll - An attempt to create a "spatially correct" Ambisonic mixdown of a multi-miked organ concert by Jörn Nettingsmeier — last modified 2009-07-15 01:26

In Summer 2008, the world's first wave field synthesis (WFS) live transmission (of Olivier Messiaen's “Livre du Saint Sacrément”) took place between Cologne Cathedral and the WFS auditorium at Technische Universität Berlin. The music of three spatially separated organ divisions was captured by multiple microphones in a mixture of spot miking and Hamasaki square technique, i.e. without a dedicated main microphone, as this was deemed desirable for the intended reconstruction on a WFS system. This paper describes an attempt to create a spatially correct mix from the concert recordings using Ambisonic encoding. The toolkit used for postproduction consists exclusively of free software, centered around JACK, Ardour and the AMB plugin set on a Linux system. The paper was originally presented at the Linux Audio Conference 2009 in Parma, Italy.
