# eJay: static recompilation of the Dance eJay audio engines

> eJay statically recompiles the audio and graphics libraries of Dance eJay titles for a new cross-platform host. Its tools lift user-supplied DLLs to C for Linux and macOS, while a host drives the original libraries on Windows; the documented eJay 2 workspace supports sample browsing, block placement and playback.
