Convert SDAT files online for free
The converter easily converts your SDAT file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other Game formats to SDAT with high quality output.
The .SDAT file extension is primarily associated with the Nintendo DS Sound Data format, a proprietary audio container developed by Nintendo for the Nitro Composer system. These archives function as a complete sound bank for Nintendo DS games, bundling background music, sound effects, and instrument libraries into a single file to save cartridge space. Internally, an SDAT file is a complex directory containing SSEQ (music sequences similar to MIDI), .SBNK (sound banks), and .SWAR (wave archives/samples).
Users typically look to convert these files to extract the game's original soundtrack (OST) or to access the instrument samples for music production. However, because the file relies on the Nintendo DS hardware to synthesize audio in real-time, you cannot simply open it in standard media players like VLC or Windows Media Player. Direct conversion to MP3 is not possible without an emulation or extraction step. The most reliable workflow involves using specialized tools like VGMTrans to parse the archive and convert the internal sequences into standard MID (MIDI) files and SF2 (SoundFont) banks, or to render them directly as WAV audio.
Note: A minority of .SDAT files may be encrypted data containers for Sony PlayStation systems (related to NPDRM/activation) or player data files for the mobile game AFK Arena. These variants are typically encrypted or obfuscated and cannot be converted into viewable formats.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SDAT converter.
