The format is associated with the first-generation Sony PlayStation, a video game console developed by Sony. PlayStation games use .sep files to store chunks of sound sequence data used during gameplay.
A .sep file belongs to the audio resources of a particular game and may depend on that game's other sound data and playback code. It is therefore a proprietary, game-specific resource rather than a general-purpose audio format.
The format is legacy technology tied to PlayStation game software. It is not normally used by current desktop audio applications, and its exact contents can vary between games.
A .sep file is not normally opened directly with a media player or standard audio editor. On the original PlayStation, the game software reads it as part of the game's stored data.
On a computer, the file generally requires a game-specific PlayStation resource or audio analysis tool, and support depends on the game from which it was extracted.
There is no general-purpose conversion from the Sony PlayStation sound sequence chunk format to a standard audio format. Because a .sep file is usually only one part of a game's sound system, converting it as a standalone file may not produce playable audio.
A compatible, game-specific extraction tool may be able to export the sequence or its associated sound resources, but the available options depend on the source game.
