Sound Shaper

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.

When a process is completed, the output soundfile appears in this main window, ready to be played. Thus one can hear the source sound, go to one of the CDP functions to alter it, and then hear the result, all from the main window of the GUI. Furthermore, this window is very compact, enabling the composer to place another application, such as a soundfile editor, on screen at the same time. 

Sound Shaper features a straightforward breakpoint editor for creating time-varying contours remember that many parameters of the CDP System support time-varying parameters and this is an essential requirement for designing dynamically rich sounds. This facility is easily accessed from the drop-down menu of the main window. 

Sound Shaper also features a useful History Function for building up libraries of complex functions which can be run at a stroke. When activated, Sound Shaper will record all the

One of the key features of Sound Shaper is its practical and concise layout. As indicated by Acher Hendirch on the CDP Web site (see web-refs.htm file in the folder various), the fundamental sequence of operations in a sound design package such as CDP is hear-alter-hear again and Sound Shaper fully supports this basic tripartite sequence by making its main window a play mechanism, with the full functionality of the CDP system available above it in the form of drop down menus (Figure 8.15).

The demo version on the CD-ROM has limited functionality, but shows the full menu structure and layout of the Sound Shaper interface. Of special interest on the accompanying CD-ROM is the Sound Shaper tutorial specially prepared for this book by Robert Thompson (in the sndshap folder). 

This package does not need installation as such simply copy the whole folder onto your hard disk. Note that the CDP programs are designed to run under DOS (command-line interface) rather than Windows (but, see Sound Shaper below). You should understand DOS in order to set up the paths, etc. as outlined in the documentation. In order to run CDP under DOS, double click on the icon . 

Some pioneering efforts have been reported in the literature to make ethane conversion to ethylene more efficient, environmentally and energy demand wise more sound, separations are shaper and more proactive to use CO2. This section highlights these efforts.
