What is a PEK file?

Audio metadata file used by Adobe applications such as Premiere Pro, After Effects, Soundbooth, and Encore; contains visual waveform data used for displaying audio waveform previews on the audio track timeline.

More Information

PEK files are part of an audio cache created by a component called the Adobe Media Encoder, which processes multimedia data in the software. PEK files are generally created alongside a .CFA file, which contains audio data in an optimized format.

You can delete PEK and CFA files, and the software will regenerate them the next time the data is needed unless the option to turn off caching is set in the application.

NOTE: Adobe SoundBooth was replaced by Adobe Audition in 2011.
