What is MIME type "application/x-pek"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-pek is a non‐standard MIME type used for Adobe Audio Waveform data. It is made to store precomputed waveform information for audio editing.

This MIME type is linked to files with the extension PEK. These files help audio software show waveforms quickly without recalculating them every time you open a project. They are mainly used to improve performance in environments that process audio waveforms.

• Main Use: Accelerates audio waveform display in editing software.
• Functionality: Holds pre-analyzed audio data for quick visual reference.
• Context: Common in Adobe audio or video editing workflows.

These files are created automatically by the software. Users normally do not need to edit or manage them manually.
