Description

This plugin takes a mix in the FuMa ambisonic convention and converts it to third order ambisonics (O3A) as used by the current version of these plugins. FuMa was used by old versions of these plugins (prior to version 2.0) and is an extension of classic First Order Ambisonics.

You can convert back with the O3A Decoder - FuMa plugin.

In Pro Tools Ultimate, as the FuMa format is not supported directly as a stem format, this plugin expects audio using the ordinary ambisonic stem format. Normally this should be encoded as O3A (i.e. SN3D/ACN), so we are "misusing" the format here.

Orders

This plugin expects third order FuMa input. If you only have first or second order, feed this to the first four or nine input channels and feed silence to the rest.

Alternatively, the O3A Injector - O1A or O2A plugins can be "misused" to increase the order of the FuMa material as this is a rare case where a plugin will work correctly for both SN3D and FuMa.

The plugin is available in the O3A Core plugin library.
