# fmod-toolkit

License: permissive · Maintenance: active · Downloads: 136.6K/mo

## What it is and what it does

fmod_toolkit is a Python wrapper around FMOD Engine 2.00.10 that converts FMOD sound bank files (FSB format) into standard WAV audio files. It bundles pre-compiled FMOD libraries for Windows, macOS, and Linux, eliminating the need to manually install FMOD separately. You load FSB binary data, specify output parameters like channel count and sample rate, and iterate over the resulting WAV files to save them to disk.

The package depends on pyfmodex for the underlying FMOD bindings. It supports FSB files but does not yet handle RIFF-based .bank files. You can override the bundled FMOD library by setting the PYFMODEX_DLL_PATH environment variable, which is useful on unsupported platforms. The bundled Linux libraries have their executable stack flag cleared for security.

Use it for:

- Extract audio tracks from game sound banks for analysis, remixing, or archival purposes.
- Batch convert FSB files to WAV for use in audio editing or post-production workflows.
- Integrate FMOD sound asset extraction into game modding or asset management tools.
- Migrate audio from legacy FMOD-based projects to standard WAV format for compatibility.
- Automate sound bank processing in game development pipelines without manual library setup.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Extracts and exports audio from FMOD sound bank files (FSB format) to WAV format, with pre-bundled FMOD Engine 2.00.10 libraries for cross-platform use.

Yes, if you need to extract audio from FSB files and are comfortable with the FSB-only limitation. The MIT license is permissive, install friction is manageable with pre-built wheels, there are no known vulnerabilities, and the package is actively maintained. Not worth installing if you need to work with RIFF-based .bank files or require support for FMOD versions other than 2.00.10.

## Install

pip install fmod-toolkit
uv add fmod-toolkit
poetry add fmod-toolkit

## Installing fmod-toolkit

Before you install: Medium install friction due to compiled binary wheels; however, the package provides pre-built wheels for common platforms (Windows, macOS, Linux on x86_64, ARM, and musl systems) and supports Python 3.8+. Repository is active with recent commits.

License in practice: MIT License permits commercial and private use, modification, and distribution with minimal restrictions—only requiring preservation of copyright and license notices. No notable constraints for most use cases.

Quickstart:

from fmod_toolkit import raw_to_wav

fsb_data = open('soundbank.fsb', 'rb').read()
for filename, filedata in raw_to_wav(fsb_data, 'soundbank', 2, 44100):
    with open(filename, 'wb') as f:
        f.write(filedata)

Requires pyfmodex as a runtime dependency; FSB files are supported but RIFF-based .bank files are not currently supported.

Verify before relying:

- Whether FMOD Engine 2.00.10 meets licensing or feature requirements for your use case
- Performance characteristics when processing large or numerous FSB files
- Compatibility with FMOD files created by specific game engines or tools
