(registered 2026-10-22, last updated 2026-10-22)

Media type name: audio

Media subtype name: prs.elupon-eua

Required parameters: N/A. The decoder assumes fixed parameters of 48000 Hz, 8-bit, Stereo, Interleaved by default.

Optional parameters: N/A.

Encoding considerations: binary

Security considerations: The media type contains purely raw binary interleaved audio samples formatted specifically for the ELUPON EUAL7 architecture. The format does not contain executable code, scripts, macros, or dynamic active content. Decoding is performed via strict linear arithmetic transformations on static byte streams, and the format poses no risk of code execution, buffer overflow exploits, or privacy violations to the host system.

Interoperability considerations: N/A. The format is designed to be cross-platform as it relies on a standard interleaved binary structure.

Published specification: Full technical specification, reference Python implementation, and open-source licensing information for the EUA (Elupon Universal Audio) format are publicly available in the official repository:

https://github.com/Elupon/ELUPON-EUA-Codec

The format starts with a 5-byte magic number ASCII signature "EUAL7" followed by raw 8-bit, 48kHz, Stereo, Interleaved PCM audio data blocks.

Applications which use this media: Custom media players and scripts developed for the Elupon ecosystem (such as Android AudioTrack-based playback applications).

Fragment identifier considerations: None.

Restrictions on usage: None.

Additional information:

1. Deprecated alias names for this type: None.
2. Magic number(s): 0:5[EUAL7]
3. File extension(s): eua
4. Macintosh file type code: None.
5. Object Identifiers: None.
