About MSF
MSF, Sony's MultiStream File, is the sound format of the PlayStation 3's tools, and many PS3 games keep their music, voices and effects in it.
An MSF has a small header starting with MSF, with the sound's codec, channels, rate, loop and often a name, and the sound right after it: PCM, PlayStation's ADPCM, MP3 or ATRAC3.
Filepeek plays an MSF in your browser with vgmstream, twice through its loop and then a fade, with its waveform, speeds and tags, and Export saves it as MP3 or WAV. ATRAC3 doesn't play, and Filepeek says so.

Questions
How do I play an MSF file?
Drop it on this page or choose Peek an MSF. It plays in your browser, twice through its loop and then a 5 second fade, the way a game loops its music.
Can I turn an MSF into an MP3?
Yes. Choose Export, then Save as MP3 or WAV, and the sound is saved as it plays here, loop and fade included.
Is the .msf from my Thunderbird folder a sound?
No. Thunderbird names its mail folders' summaries .msf too, and those are text, which opens here as text.
Why won't some MSF files play?
An MSF can hold ATRAC3, Sony's codec of the time, which Filepeek doesn't play, and it says so.
