Is there a simple way to convert .sfk peak files to .mp3 format?
SKF files are merely temporary cache files associated with Sound Forge Pro audio projects. Converting these Sound Forge Pro Audio Peak Files directly to MP3 Audio Files (.sfk to .mp3 conversion) is not possible. SFK files do not contain any audio data.
We are not aware of any audio editing program or (online) conversion tool, which would allow you to convert SFK to MP3.
In a word, direct sfk to mp3 conversion is not possible.
So don't expect any so-called sfk to mp3 converter or sfk to mp3 free online conversion tool available.
