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. Something which closely resembles the original input sound (a resynthesis) can be generated by computing and adding all of the individual time varying sinusoidal waves together. In almost all cases the resynthesis will not be exactly identical to the original sound (although it is possible to get very close). Aside from offering a very detailed analysis of the time varying frequency content of a sound, a sinusoidal model offers a great deal of flexibility for editing and manipulation. SPEAR supports flexible selection and immediate manipulation of analysis data, cut and paste, and unlimited undo/redo. Hundreds of simultaneous partials can be synthesized in real-time and documents may contain thousands of individual partials dispersed in time. SPEAR also supports a variety of standard file formats for the import and export of analysis data. Read more in the ICMC paper "Software for Spectral Analysis, Editing, and Synthesis." (pdf) or in the dissertation paper Spectral Analysis, Editing, and Resynthesis: Methods and Applications.

WaveSurfer is an open source tool for sound visualization and manipulation. Typical applications are speech/sound analysis and sound annotation/transcription. WaveSurfer may be extended by plug-ins as well as embedded in other applications.

Scapes is a real-time effects processor and sound generator based on feedback. It uses six independent granular delays, extensive modulation options, a gate sequencer and familiar synth style controls to dynamically manipulate the sound. With Scapes you can create high quality and unique soundscapes, rhythms and sound effects perfectly suited for use in music, film and game audio. You can easily connect it to your favorite hardware controller or iPad and immediately have fun. Keep an eye on our video and audio section (click the tabs), where we'll be posting new videos often.

PERFORMER is a revolutionary way to control your music software. It uses multi-touch technology to the full. Instead of traditional faders and knobs, use multi-touch and gestures to manipulate PERFORMER's beautiful shapes to dynamically control your computer's software instruments in real-time. In the studio, it allows the artist to approach their sound-design routine from a new, inspiring angle: to reconnect to their software instruments and Digital Audio Workstations by using Performer's revolutionary interface and arriving at sounds and progressions impossible with traditional controllers. But PERFORMER was also made to be seen! On the stage, alongside with VISUALISER (PERFORMER's big-screen visual output module, which is coming soon), PERFORMER creates an engaging live show that is indeed "alive".
