What is a PKF file?
The PKF file format is commonly associated with Adobe Audition, a professional audio editing software. It stands for “Peak” file, and it is generated by Audition to store information about audio peak levels. This information is used for various purposes, including waveform display, audio editing, and processing.
PKF File Format - More Information
When you import audio files into Adobe Audition, it analyzes audio and generates corresponding .pkf files alongside the original audio files. These .pkf files contain data about maximum peak levels of the audio waveform, allowing Audition to quickly redraw waveform display without repeatedly analyzing audio file.
PKF files are usually stored in the same directory as corresponding audio files and have same filename, with “.pkf” extension appended to it.
The .pkf file format primarily contains metadata related to audio file it corresponds to. This metadata includes information about peak levels, which are the highest amplitude points in audio waveform.
PKF files are relatively small compared to original audio files because they store metadata rather than actual audio data. They typically only contain necessary information to represent peak levels accurately.
PKF files are automatically generated by Adobe Audition or similar audio editing software when audio files are imported or analyzed within program. The software calculates peak levels of audio waveform and saves this data in the corresponding .pkf file.

PKF vs. Other Olympus Formats
It’s easy to confuse PKF with other Olympus formats like DSS and NSA.
DSS: The original, industry-standard format for voice dictation and recording, often used in more professional dictation devices.
NSA: A modern, XML-based format used in higher-end Olympus recorders, offering greater stability and corruption resistance.
PKF: The format tailored for the compact, consumer-focused “Pocket” recorder line, emphasizing simplicity and storage efficiency. While they share the same core purpose and some technological DNA, each format is optimized for its specific device class and use-case intensity.
How to open a PKF file?
Since .pkf files are associated with Adobe Audition, the primary way to open them is by using Adobe Audition software. Here is how you can open a .pkf file in Adobe Audition:
- Open Adobe Audition.
- Go to “File” > “Open…”
- Navigate to the location of .pkf file.
- Select the .pkf file and click “Open.”
- The .pkf file will open in Adobe Audition, allowing you to view and edit associated audio waveform.
PKF files can be opened using the following programs
- Adobe Audition 2023
- Adobe Premiere Pro 2023
FAQ
Q1: How can I open a PKF file on my Windows PC?
A: You can open PKF files using dedicated Olympus software like Olympus Sonority or, for simple playback, in VLC Media Player.
Q2: Can I convert a PKF file to MP3?
A: Yes, you can convert PKF files to MP3 using the “Export” or “Save As” function in Olympus Sonority or with a compatible audio conversion tool.
Q3: What does PKF stand for?
A: PKF stands for Pocket File, indicating its use on Olympus Pocket Digital Voice Recorders.
Q4: Is the PKF format lossless?
A: No, PKF uses lossy compression optimized for speech to prioritize small file sizes over perfect, uncompressed audio quality.
Q5: Why won’t my PKF file play in a standard media player?
A: Standard media players lack the proprietary codec; use Olympus software or a versatile player like VLC which has broader format support.
