.HDP File Association 2
Audio clip created by MAGIX audio and video editing software, such as Movie Edit Pro (MEP) and Samplitude Music Studio; describes a sound object that has been imported or captured directly in the software; allows destructive edits to the audio data without affecting the original audio; generated automatically when dragging an audio file onto the movie timeline, or when importing a video file that includes audio data.
NOTE: HDP files are used internally by Movie Edit Pro when the user edits movies. If they are manually deleted, they will be recreated the next time the audio object is accessed in MEP.
