ADX is a proprietary compressed audio format developed by CRI Middleware for use in video games. It uses ADPCM-based compression to store sound effects and music efficiently. The format is widely used in games on Sega and other platforms that utilize CRI's audio middleware.
A FLAC file is an audio file compressed in the Free Lossless Audio Codec (FLAC) format, which is an open source lossless audio compression format. It is similar to an .MP3 file, but is compressed without any loss in quality or loss of any original audio data.
