Gerald Maruccia shared his audio upmix algorithms.
DCP-o-matic was packaged for Arch Linux by Stefan Karner and Benjamin Radel.
Parts of DCP-o-matic are derived from Terrence Meiczinger's excellent OpenDCP. DCP-o-matic also makes use of the following libraries:
| FFmpeg | libsndfile | OpenSSL |
| libopenjpeg | Boost | Fontconfig |
| libssh | Glib | xmlsec |
| wxWidgets | libcurl | RtAudio |
| libicu | libsamplerate | libzip |
| pango/pangomm | cairo/cairomm | libxml++ |
| nettle |
It also includes code taken from Paul Davis' Ardour and uses Ole Laursen's string composition library.
Some web-site icons are taken from The Open Clip-art Library.
