What is this?
ALH Pro is a free Windows desktop app that uses AI to upscale and enhance images, videos, and audio entirely on your local machine, covering image super-resolution, AI background removal, video super-resolution, frame interpolation, duplicate-frame removal, and audio separation/enhancement.

Only the bundled third-party engines keep their original open-source licenses.
