Description

This plugin takes a mix in the FuMa ambisonic convention and converts it to seventh order ambisonics (O7A) 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.

Note that this conversion does not sharpen the spatial image in any way, so the signal is still essentially third order and does not carry the detail you might normally expect in a seventh order stream.

You can convert back with the O7A Decoder - FuMa plugin.

Orders

This plugin expects seventh 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 O7A Injector - O1A, O2A or O3A 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 O7A Core plugin library.
