## Why It Matters
UFMOD matters because it provides a highly compact, assembly-language implementation of a module audio player suitable for size-constrained applications such as demos, intros, and embedded or minimal operating systems. Its small footprint and x86 assembly implementation make it attractive to demoscene developers, hobbyist programmers, and projects that prioritize minimal resource usage and tight control over audio playback. Because it supports multiple operating systems (Windows, Linux, FreeBSD, KolibriOS) and multiple backends (ALSA, Windows Multimedia Extensions, DirectSound, OpenAL), UFMOD can be integrated into cross-platform toolchains and small multimedia projects. The library’s focus on module formats (Extended Module) aligns it with tracker-based music workflows common in game development and the demoscene. Hosting and distribution via SourceForge, a stable release history (stable version 1.25.2a dated 2020-10-12), and available user manuals in several languages increase its accessibility. Users should be aware of at least one recorded security entry (CVE-2007-3965) when evaluating deployment for modern systems.

## Notable For
- Implementation in x86 assembly language, targeting compactness and performance.  
- Popularity within demoscene and hacker-culture contexts for size-constrained multimedia projects.  
- Cross-platform support including KolibriOS, an OS also written largely in assembly.  
- Distribution as freeware with project hosting and source downloads on SourceForge.  
- Support for module music formats (Extended Module) and inclusion of related utilities such as XMStrip.
