SPEAR is an application for audio analysis editing and synthesis. The analysis procedure (which is based on the traditional McAulay-Quatieri technique) attempts to represent a sound with many individual sinusoidal tracks (partials) each corresponding to a single sinusoidal wave with time varying frequency and amplitude.
Spear somewhat resemblesAudioSculpt but lack most of the more advanced features of AudioSculpt. Still a welcome addition to the toolbox. Spear was described in an ICMC 2005 paper.
