Abstract

The ideal panning algorithm for creating virtual locations in surround sound would have small variations in energy as the target locations change. All-Round Ambisonic Panning (AllRAP) is an algorithm that aims for creating phantom sources of stable loudness and adjustable width for arbitrary loudspeaker arrangements. This is achieved by combining an extended version of Vector-Base Amplitude Panning (VBAP) with Ambisonics. Ambisonics as audio format needs to be decoded to loudspeakers, which conventionally requires either dedicated loudspeaker arrangements or sophisticated mathematical treatment. In contrast, the proposed panning and decoding algorithm is highly generic and easily applicable to any arrangement of loudspeakers and platform with only basic computational capacities. Because AllRAP also works with loudspeaker arrangements covering only a part of a sphere, it is suitable for upcoming surround with height formats.
