2. Supported file types

As manakoAT likes to say, the extension doesn’t really mean anything, but it’s the most obvious way to identify files.

  • Others

Sometimes standard codecs come in non-standard layouts that aren’t normally supported by other players (like multiple .ogg or .mp3 files chunked and interleaved together in custom ways).

Some codecs are not fully correct compared to the games due to minor bugs, but in most cases it isn’t audible, and general accuracy is high, with emphasis in proper support of encoder delay, accurate sample counts and seeking that other plugins may lack.

Note that vgmstream doesn’t (can’t) reproduce in-game music 1:1, as internal resampling, filters, volume, etc, are not replicated.
