About ADX files

A .ADX file is primarily a CRI Middleware audio stream file. It is a lossy proprietary audio format developed for video games, heavily used on consoles like Sega Dreamcast, PlayStation 2, GameCube, and Wii to handle looping background music and voice tracks. Other less common uses include Componentace Absolute Database files or compiled ERP source code for Sage X3. The major disadvantage of the .ADX format is its proprietary lock-in. You cannot play a .ADX file natively on Windows, macOS, Android, or iOS. Major media players reject it without specialized plugins like vgmstream. Because the codec is obscure, sharing these files directly with non-technical users is impossible. To play or edit the audio, conversion is required. For web use or standard playback, convert to MP3 or OGG. For editing and archiving without further quality loss, convert to WAV or FLAC. Note that converting a looping .ADX track will cause it to lose its internal loop points, meaning it will only play through once. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
