File type: Audio and sound file
Files with lpcm file extension contain audio data used by Microsoft Windows Movie Maker on Windows.
File type category:
Audio and sound file
Date updated: October 6, 2026
The lpcm file extension is associated with Windows Movie Maker, Microsoft's video-editing software for Microsoft Windows.
An lpcm file stores audio data used by Movie Maker. The associated MIME type is audio/l16.
The format is tied to older Windows Movie Maker installations. Windows Movie Maker is no longer included with current versions of Windows.
Open an lpcm file with Windows Movie Maker on Windows, preferably through the Movie Maker project that uses the file. The file may be supporting project media rather than a file intended to be opened independently.
Because Movie Maker is discontinued, it may not be available on a current Windows installation. If the original project is unavailable, the file may not open correctly in other applications.
There is no dependable general-purpose conversion workflow for an lpcm file outside Windows Movie Maker. If the file belongs to a Movie Maker project, open the project in Movie Maker and export or publish the completed project to a supported video format.
Converting the audio alone requires an application that supports this specific Movie Maker data and knows its audio parameters; a generic audio conversion may not recognize the file correctly.
