ADXlossy compressed audio file (.adx)
.adx file signature | application/octet-stream
ADX is a lossy compressed audio file format developed by CRI Middleware and used in its audio tools and middleware. It is commonly used for background music, voice, and sound effects in video games and other interactive media. The format has long been associated with console game development and is generally considered safe, though playback support may depend on compatible decoders.

What are the magic bytes for .adx files?
The magic bytes for ADXlossy compressed audio file files are 03 00 00 00 41 50 50 52 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .adx file?
To validate a .adx file, read the first bytes of the file and compare them against the known magic bytes (03 00 00 00 41 50 50 52) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .adx files?
There is no officially registered MIME type for .adx files. Systems typically use application/octet-stream as a generic fallback when handling this format.
Is it safe to open .adx files?
ADXlossy compressed audio file (.adx) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
