SOUNDSHAPER is a free PC interface for
CDP, the suite of sound transforming tools developed over many years by
the COMPOSERS' DESKTOP PROJECT.
The new version of Soundshaper fully supports the latest CDP
Release 7.1, 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 5.09
Soundshaper is built around a multi-process environment, with easy construction of patches
in an innovative patch grid (READ MORE). Save patches and recall these as
fully-editable presets, for use with different source files. Click on any cell to see and hear each stage of building the process chain or save the sound to file.
Soundshaper 5 features:
- Built-in streaming soundfile viewer/editor, using the BASS audio library
- Easily edit and process part of the sound.
- Multi-layered patches: treat a whole sequence of processes as a single object and build this into a higher-level patch. Re-use the object many times.
- One-click recall of favourite patches.
- One-click recall of favourite processes and settings.
- Run Csound scripts alongside CDP.
- Build your own scripts and run these within a patch.
- Choose from a number of skinned styles, including several dark themes.
Recent upgrades include full support for multiple channels, multiple parameter sets and up to 16 separate sound-processing chains. CDP's various file types are
converted seamlessly behind the scenes. Output is saved to temporary files,
ready for instant auditioning, viewing, editing and further processing.
Sounds 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 32 and 64-bit
versions of Windows from Vista to Windows 10. Work is also underway to port Soundshaper to Mac OSX and hopefully Linux.
