What is an SFK file?
An SFK file stores the waveform image of an audio wave (.WAV) file saved by MAGIX Sound Forge Pro or VEGAS Pro. It does not store audio data; the applications reference the SFK file to display the WAV file's waveform image. SFK files replaced .SFL files, which older versions of Sound Forge Pro create.
More Information
When opening a WAV file with Sound Forge Pro or VEGAS Pro, the software automatically creates the SFK file in the same directory as the WAV file. If another program modifies the related WAV audio file, you can regenerate the SFK peak file by selecting Rebuild Peak Data from the Special menu in Sound Forge.
NOTE: Sonic Foundry initially developed Sound Forge Pro until Sony acquired the application in 2003. Then, MAGIX acquired Sound Forge Pro in 2016.
Common SFK Filenames
[same_name_as_the_WAV_file].sfk - MAGIX Sound Forge Pro or VEGAS Pro name SFK files with the same name as the WAV file. For example, an audio.wav is accompanied by an audio.sfk file.
How to open an SFK file
You should not attempt to open SFK files since MAGIX Sound Forge Pro and VEGAS Pro reference the file when opening the WAV file for which it contains its information.
