The CDP sound transformation toolkit

The CDP sound transformation toolkit is part of a large package called The CDP Computer Music Workstation currently available for the Atari Falcon, PC-compatible and Silicon Graphics platforms. CDP stands for Composer s Desktop Project and it was created in the mid-1980s in York by a pool of British composers and sound engineers with the objective 

As for the Spectral Sound Transformation group, it includes dozens of highly specialised programs for spectral manipulation, which constitute one of the most powerful toolkits of its kind. They deal directly with the timbre or tone colour of a sound, thus making possible the modification of timbre in unprecedented ways. The Spectral Sound Transformation tools carry out a spectral analysis of the sound to user-defined degrees of complexity, whereupon the numerical data can be manipulated in many different ways (see Chapter 3).

Sound Shaper is a GUI for the CDP sound transformation toolkit, developed by Robert Fraser. This comprehensive piece of work is written in Delphi and is available for the IBM PC-compatible Windows platforms. It sits on top of and transparently makes use of the standard CDP command line set of programs, so it will work immediately with any current Release 4 version of the CDP System.
