FM (Creative FM Blaster)

.FM is a radio transmission file delivered, and saved, by Creative FM Blaster. The file type is an RIFF container holding either a wav or a snd format audio file.

The .FM extension was used by Creative for recorded files saved from live stream broadcasts via the FM Blaster radio card; a popular PCI and ISA format radio reception card in the 1990s before internet radio was commonplace. The FM format name is a misnomer as the files recorded not just FM radio but AM, Short wave, marine, and ham radio transmission. Later TV blaster cards recorder audio only as FM as well. The video and audio format extension being .tv and .CTV

Most extension agnostic programs will open the .FM files as their native format.
