FRFR transparent capture

This is a dummy capture of the original sweep training signal, meant to occupy the NAM blocks of speakers/cabs that lack the option to disable head/cab simulation, so they can be used as an FRFR speaker with other, more capable, NAM players. One use case is to download this and reupload to your account PRIVATELY so you can fetch it from your device's T3K integration, as publishing this straight as head or rig capture is against guidelines :3
