Audio plugin for Pro Tools audio production software; adds effects and filters that can be applied to audio tracks within a Pro Tools session. In Mac OS X, DPM files should be stored in the "/Library/Application Support/Digidesgin/Plugins" folder. In Windows, DPM files should be placed in the "\Program Files\Common Files\Digidesign\DAE\Plug-Ins" directory. NOTE: In order for older plugins to work in Pro Tools 8, the file extension ".dpm" may need to be added to the filename in order for Pro Tools to recognize it.
