Compensated Amplitude Panning (CAP) is a spatial audio reproduction method for loudspeakers that takes the listener head orientation into account. Using CAP it is possible to produce stable images in all directions using only two loudspeakers. In its original formulation CAP is inherently an object-based method, with each image produced separately. Here a natural method is presented for dynamically decoding a first order Ambisonic encoding that is equivalent to using CAP to reproduce the constituents of the encoding. This has the advantage of channel-based methods that complex scenes can be reproduced with little cost, and existing Ambisonic encodings, such as those used in 360° video, can be reproduced directly.
