Extract text from audio peak files (PKF)
To convert PKF peak files to another format, you need Adobe Audition or other Data software.
To convert other file formats to the "Audio Cache File" file type, you need software like Adobe Audition or a similar tool.
A .PKF file is primarily an audio waveform peak file used by Adobe Audition (formerly Cool Edit Pro). It stores the visual rendering data for audio tracks, allowing the software to draw the waveform instantly on screen. A secondary use case includes legacy podcast files generated by the Pocket Recorder app by NCH Software.
Opened natively by Adobe Audition, this proprietary format causes significant confusion for end-users. The main disadvantage is that Adobe .PKF files are not audio files. They contain absolutely zero audio data and cannot be played by standard media players. Users frequently encounter errors when trying to share these files expecting the recipient to hear music or a voice recording.
You cannot directly convert an Adobe .PKF file into a playable audio format like MP3 or WAV because the sound data simply does not exist inside the file. You must find the original source audio instead. However, if your file is a Pocket Recorder format, extraction might be possible. Drag and drop your file to analyze and convert it - free, online, and without installing software on convert.guru.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PKF converter.
