About ADX Files
An .adx file is an audio file saved in the ADX Audio format, a compressed audio format developed by CRI Middleware for use in Sega video games. ADX files store high-quality audio data using adaptive differential pulse-code modulation (ADPCM), which reduces file size while maintaining good sound fidelity. Sega Dreamcast, PlayStation 2, and GameCube titles widely use the ADX format to store background music (its looping capability would play seamlessly during gameplay), sound effects, and dialogue.
ADX files are most often found within game data archives, but can also appear as standalone files when extracted from game discs or rips. They remain popular among video game modders, soundtrack collectors, and emulation enthusiasts interested in preserving or repurposing original game audio. Users can open and play .adx files by dragging them to this page on FileHelper.com.
Converting ADX Files
You can convert .adx files to other formats to improve compatibility:
- Converting to MP3: Makes ADX audio playable on nearly all devices and media players, though it applies additional lossy compression that slightly reduces audio quality compared to the original file.
- Converting to AAC: Provides efficient compression and good sound quality, producing smaller files than MP3 while maintaining compatibility with most modern devices and streaming platforms.
