Description

These simple plugins take a third order (O3A) ambisonic mix and convert it to a lower resolution first order (O1A) or second order (O2A) mix. In all cases, the SN3D convention is used.

These plugins are extremely simple and just reduce the channel count in use by discarding the later channels, which has the effect of reducing the spatial detail of the mix.

Note that some DAWs (such as Reaper) pass through channels that are not written to. These plugins will appear to have no effect in these DAWs!

These plugins can also be "misused" to reduce the order of N3D/ACN or FuMa material. This is a rare case where the same plugin will work correctly for all three ambisonic formats.

The plugin is available in the O3A Core plugin library.
