Why would anyone build with this?

REASON 1

Compress game audio to reduce file size while keeping decoding fast for real-time playback.

REASON 2

Drop the single-header library into a C or C++ project without pulling in complex third-party dependencies.

REASON 3

Stream decent-quality audio in a retro game engine or embedded system with limited storage.

REASON 4

Build a lightweight audio tool that needs speed and simplicity over studio-grade fidelity.
