How to Extract FSB Audio as OGG

Before you start

FSB is a container format used by some games and applications. You usually convert FSB to OGG on your own computer with a desktop utility that can open FSB archives. This keeps the source files on your device instead of uploading them to a service.

Check the source FSB file first. If it is part of an installed game or application, close that application before converting. Also note whether the file is read-only or inside a protected folder, because the conversion tool needs read access to the source location.

Step-by-step instructions

Use a current version of the FSB conversion tool. Older versions may not recognize newer FSB archives or may export fewer entries correctly. Keep a copy of the original FSB file before you begin.

Open the utility and load the FSB file with its Open or Add command. If the tool shows an archive list, wait until the entries appear before selecting output options.

Choose OGG as the output format. If the tool exposes conversion settings, match them to the source audio where possible. Use the same sample rate as the original unless you specifically need to change it, because an unnecessary change can affect pitch or quality.

Set a separate output folder for the converted files. Select the archive entries you need, or use the tool's extract all option. Start the conversion and wait for it to finish without opening or moving the source FSB file.

Check the output

Open the output folder and confirm that the OGG files were created. Play a short section of each file in a media player that supports OGG. Listen for missing audio, clicks, a wrong speed, or unexpected silence.

If the source archive contains many entries, compare the number of exported files with the number of entries shown by the extraction tool. A mismatch may mean that some files were skipped or that the archive list was not fully read.

Keep in mind that OGG is a lossy format. Even with good settings, the result is not an exact copy of the source audio. For most listening and editing tasks this is acceptable, but the converted file should not be treated as a preservation master.

Common problems and next steps

If the tool cannot open the FSB file, confirm that you have selected an FSB archive rather than a renamed file or an unsupported variant. Updating the extraction tool may add support for newer FSB versions.

If the exported OGG is too quiet or too loud, adjust the input level before converting again. Do not only raise the playback volume, because that can also make background noise more noticeable.

If you hear background noise that was not obvious in the source, check the source file first. Converting to OGG does not add noise, but it can make existing noise more apparent when the file is played on different speakers or headphones.

If the player will not open the output file, verify that the file has a working OGG extension and that the player supports OGG. Restart the player or try another OGG file to separate a file problem from a playback problem.

For repeated conversion work, keep the same output folder and naming scheme. That makes it easier to trace each OGG file back to its FSB archive without hunting through the source folders.
