MRC Software
Researchers at the MRC have developed a variety of bespoke software that facilitates the work that goes on in the centre, some of which is in the public domain. Notably there is a collection of Max MSP and puredata externals for dealing with ambisonics, and these algorithms are also available as VST and Audiounit plugins. The centre also produces commercial software including the MRC meter - a highly accurate audio metering plugin.
