About RSD Files

An .rsd file is an audio file saved in the RadSound Audio (RSD) format, a proprietary audio format used in various video games and multimedia applications, such as The Incredible Hulk: Ultimate Destruction and The Simpsons: Hit & Run. RSD files store compressed audio data, often using ADPCM-based encoding, to reduce file size while preserving acceptable sound quality. The format was designed for efficient real-time playback, making it suitable for background music, sound effects, and voice clips used during gameplay.

RSD files are most commonly found inside game data folders or resource archives, but may also appear as standalone files when extracted from games or development assets. They are primarily encountered by game modders, audio extractors, and preservation enthusiasts working with older or proprietary game audio formats. Users can open and play .rsd files on FileHelper.com by dragging them to the page.

Converting RSD Files

You can convert .rsd files to other formats to improve compatibility:

• Converting to MP3: Converts the audio into a universally supported format that works on almost all computers, phones, and media players, with some loss of quality due to compression.
• Converting to AAC: Re-encodes the audio using a modern codec that delivers good sound quality at smaller file sizes and is well supported on current devices and platforms.
