First Order Ambisonic (FOA) transformer

Description

Transforms (spatial domain filter) a First Order Ambisonic signal (B-format). FoaTransform provides continuously varying dynamic transforms at the audio and control rates, for static initial rate transforms see FoaXform.

NOTE: FoaTransform is a convenience wrapper around the various transformer UGens.
