TheComposers Desktop Project (CDP) is an international cooperative network based in theUnited Kingdom that has been developingsoftware for working with sound materials since 1986. Working on a cooperative basis and motivated by user-specific compositional needs, the project has focused on the development of precise, detailed and multifacetedDSP-based sound transformation tools. Currently, CDP provides sound transformation software (named after the project itself) forWindows andMac OS X that has been evolving for over 20 years.
In 2014 the main components of the CDP were released as anopen-source package licensed under theLGPL.Makefiles are now available for Windows, OSX, andLinux.
Originally, after a study to determine if it was possible and/or feasible to portCMusic fromUNIXmainframe systems,[1] the project released the CDP software along with correspondingSoundSTreamer hardware for theAtari ST[2] and later ported the software toDOS. The software tool-set is designed specifically to transformsound samples mostly viaoffline processing (non-real time); the software is considered complementary to real-time processing andaudio sequencers.
