Introduction to Pro Tools Plug-Ins : Audio Plug-Ins Overview : Plug-In Formats : AudioSuite Plug-Ins

AudioSuite Plug-Ins
AudioSuite plug-ins are used to process and write (“render”) audio files on disk, rather than nondestructively in real time. Depending on how you configure a non-real-time AudioSuite plug-in, it either creates an entirely new audio file, or alters the original source audio file.
AudioSuite plug-ins can be used on all Pro Tools systems and Avid software, as well as any third-party software that supports AudioSuite.
AudioSuite plug-in files may use either the “.aaxplugin” or “.dpm” file suffix.
