ADX files exist as 2 different types. Please find information about each of them below.

The ADX file extension stands for Approach Index File. It is created by Microsoft Access. This type of file is used to speed up retrieving records from tables in databases. It keeps track of fields in a table. It stores an index for each field to search records quickly inside the table.
The ADX file is primarily used by Microsoft Access’s query engine. It accelerates finding related records in fields and tables within a database. It can be generated manually. It can also be generated by running select queries in Access.
ADX files contain background music for video games. They are meant to loop during gameplay. ADX files are compressed with a lossy Adaptive Differential Pulse-Code Modulation variant. Some Sofdec videos contain interleaved ADX audio.
You can open an ADX file with vgmstream software. It plays the audio in ADX files on multiple platforms. You can also play ADX files using Foobar2000 or Winamp. You need to install their vgmstream plug-ins first. With the plug-in, Foobar2000 converts ADX files to WAV and other formats.

The ADX audio format developed by CRI Middleware stores audio samples efficiently by recording the error relative to a prediction function. This trades accuracy for size using small 4-bit samples. The auditory system tolerates the resulting noise.

ADX is lossy but, unlike MP3s, doesn’t use a psychoacoustic model to reduce complexity. Instead, ADX leverages the auditory system’s noise tolerance for compact storage. For 5.1 audio, AIX interleaves three 2-channel ADX files.
The basic ADX structure is used in related CRI formats. Each format has a different “format” byte value. ADX is intended for game background music thanks to built-in looping. It appears in some Sonic the Hedgehog games’ voice and sound recordings.
