How to convert son to wav file

It should be possible to convert Beam Software SiFF Audio Files directly to WAVE Audio Files (.son to .wav conversion), although it seems there aren't many options for a reliable and smooth conversion.

Your best bet would be using tools, such as FFmpeg or VLC Media Player, which claim to be perfectly capable of converting loaded SON files to more common audio formats, including WAV.
