Frequently Asked Questions
What is ADX format?
ADX is an audio format developed by CRI Middleware, commonly used in video games, particularly Sega titles like Sonic and Dreamcast games. It uses ADPCM compression for efficient storage.
What are ADX files used for?
ADX files are primarily used in video games for background music, sound effects, and voice acting. The format is popular in Japanese games and was widely used on Sega consoles.
What bitrate should I use?
192 kbps CBR or VBR quality 2 provides excellent quality for game music. 256 kbps CBR or VBR quality 0 offers near-transparent quality. Lower settings (128 kbps) work for voice samples.
Will I lose quality converting from ADX?
ADX uses ADPCM compression which is lossy. Converting to MP3 (also lossy) will result in some quality loss, but with good settings (192+ kbps or VBR Q2+) the difference is minimal for most listeners.
Can I play ADX files directly?
ADX files require special software or plugins to play directly. Converting to MP3 makes them compatible with all standard media players and devices.
