![]() if the main output of your project is to be in first order, then you can undo this gain by setting the envelopment slider to 0.27. This gain is automatically applied when the Envelopment value is set to its default of 0.1. When using the spatialiser plugin in first order B-format mode an additional gain boost is applied to the XYZ channels of the first order signal. To counteract this, a gain adjustment is required to optimise the FOA signal for playback as part of a second order Ambisonic field. Using first order Ambisonic signals within a higher order Ambisonic field can result in the lower order signal sounding more smeared out and diffuse. The output of the Spatialiser plugin and for exporting the spatial The Spatial Workstation uses 2nd or 3rd order ambiX as We will refer to this convention asī-format (ambiX). This is characterised by a differentĬhannel ordering and weighting. ![]() A more extendable convention to the traditional B-format (FuMa) hasīeen proposed, know as ambiX.Is defined using the channel ordering and weighting proposed by FurseĪnd Malham (often abbreviated to FuMa).
