This paper presents a novel panning algorithm called Speaker-Placement Correction Amplitude Panning (SPCAP)which guarantees conservation of loudspeaker power output. The method is appropriate for any speakerarrangement (e.g. ITU 5.1, 10.2, etc.), and scales with the number of speakers. SPCAP works by correcting initialpan values based on speaker placement to achieve constant power output. Because panning occurs over an arbitrarynumber of speakers (I.e. Is not pair-wise), SPCAP provides two significant advantages over discrete panningschemes. First, pan values for current and future surround-sound formats (e.g. 5.1 and 10.2) are guaranteed toconserve power under any lower-resolution setup, making dynamic up/down mixing in non-standard setups feasible.Second, SPCAP provides a framework for producing wide (non point-source) sounds.
