Convert BIK to WAV

Although it is not the most common conversion request, converting Bink Video Files directly to Wave Audio Files (.bik to .wav conversion) should still be possible. It typically relates to users looking for ways to extract the audio track (WAV) from a BIK video.

It appears that your options are somewhat limited, but try using, for instance, the Freemake Video Converter, as it should allow you to import BIK video files and export their extracted audio track in WAV format.
