Convert FRG to FLAC

You will need the original software to be able to convert Sound Forge Pro Project Files directly to Free Lossless Audio Codec Files (.frg to .flac conversion), although it is not a conversion in the proper sense.

FRG is a proprietary file format, which means there are no existing third-party alternatives capable of such conversion. Use, therefore, Sound Forge Pro itself, as it allows users to export its FRG projects in numerous formats, including FLAC.
