This software, known as SPEAR, is designed for analyzing and resynthesizing sound waves based on sinusoidal partial editing. The program allows users to manipulate specific frequency components of a sound file for precise control over editing and resynthesis.
SPEAR is a powerful application designed for audio analysis, editing, and synthesis. The software uses the traditional McAulay-Quatieri technique to analyze sound and represent it through individual sinusoidal tracks, also known as partials. These tracks comprise a single sinusoidal wave with time-varying frequency and amplitude.
By computing and adding all of the individual sinusoidal waves together, one can generate a resynthesis of the original sound, which closely resembles the input sound. However, it is important to note that in most cases, the resynthesis will not be exactly identical to the original sound.
The sinusoidal model offers a great deal of flexibility for editing and manipulation, in addition to providing a detailed analysis of the time-varying frequency content of a sound. SPEAR supports immediate manipulation and flexible selection of analysis data, cut and paste functionality, and an unlimited undo/redo feature.
SPEAR can synthesize hundreds of simultaneous partials in real-time, and documents can contain thousands of individual partials dispersed in time. The software also supports a variety of standard file formats for importing and exporting analysis data. Overall, SPEAR is an excellent tool for audio professionals who require sophisticated editing and synthesis capabilities.
