VLDCMCaR (pronounced vldcmcar) is a MATLAB application for exploring concatenative audio synthesis using six independent matching criteria. The entire application is encompassed in a graphical user interface (GUI). Using this program a sound or composition can be concatenatively synthesized using audio segments from a corpus database of any size. Mahler can be synthesized using hours of Lawrence Welk; howling monkeys can approximate President Bush’s speech; and a Schoenberg string quartet can be remixed using Anthony Braxton playing alto saxaphone. A composer could also record a vocalization of a composition and fill it in using any sound material desired.
