AB  - The Source-Distance Based Amplitude Panning (SDAP) algorithm offers a new approach in determining gain amounts for distributed loudspeakers in a three-dimensional (3D) space. Similar to the 3D implementation of Vector Based Amplitude Panning (VBAP), this method is based on the use of non-overlapping triangular regions formed by the known locations of sets of three loudspeakers. Unlike VBAP, however, this method compares the location of the panning vector to the surface formed by the triangular region and uses Barycentric coordinates to determine the speakers' respective amplitudes. In addition, SDAP removes the possibility of negative amplitudes as may appear in VBAP. Informal listening test results showed that the perceived position of the sound source was perceptually well matched to the target position.
