SOUNDSHAPER is a free PC interface for
CDP, the suite of sound transformation tools developed since 1986 by
the COMPOSERS' DESKTOP PROJECT.
The new version of Soundshaper fully supports the latest CDP
Release 7, which is also a FREE DOWNLOAD.
CDP has a huge range of processes and tools for manipulating, creating and altering sounds
to make music, many of which are not available elsewhere. Soundshaper makes CDP quick and easy to use.
Together, SOUNDSHAPER and CDP
comprise one of the most comprehensive experimental sound design packages available.
Soundshaper's sound processing engine, CDP, covers every area of sound design.
CDP is not a real-time system: all processes alter an existing file and write a new one.
However, on modern machines, a sequence of CDP processes can often be run faster than real-time.
CDP is very strong on granular and textural techniques, and processes which reorganize
the order of events. It also has a large range of spectral processes, which alter a sound's
time-varying frequencies: the inner 'guts' of its timbre. You can also separately extract
fomants (peaks in the spectrum) or pitch, and manipulate or combine these characteristics
in new and unusual ways.
CDP 6 (2010) introduced many processes for working with multi-channel sound,
including innovative sound diffusion programs as well as spectral splitting and
rhythm-transforming functions, and a fast spectrally-based convolver. CDP 7
(2014) added over 30 new functions which greatly enhance the overall provision in several

LATEST VERSION SOUNDSHAPER 4.5
Soundshaper is built around a multi-process environment, with easy construction of patches
in an innovative patch grid (see screenshot above). Patches can be saved and recalled as
fully-editable presets, for use with different source files. As you build a patch, you are
working with processed sounds, so you can hear the effects of the process chain at any stage.
The latest version (4.5) has support for sub-patches, in which a whole patch is run within
one cell of the patchgrid. Patches containing sub-patches can be saved and re-run as normal.
Soundshaper has been extensively upgraded in recent versions to support multiple channels,
multiple parameter sets and up to 16 sound-streams. CDP's various file types are
converted seamlessly behind the scenes and output files are saved as temporary files,
ready for auditioning, viewing, editing and further processing.
Files can be saved permanently at any point and any process can be edited or replaced with
Soundshaper has full support for CDP 7 and is compatible with all
versions of Windows from XP to Windows 10. Although currently
available only for the PC, work is underway to port Soundshaper to Mac OSX and Linux.
