What it is

OpenHomeKaraoke is a free, open-source karaoke system for searching, downloading, and queueing songs at home. It can find songs on YouTube and download from YouTube and other video sites, including Youku and Bilibili. Playback supports MP3 and CDG files, including ZIP bundles. A DNN-based vocal splitter offers instrumental, vocal, or combined playback and requires PyTorch, preferably with GPU support; stereo track subtraction is also described. Voice search and queueing use OpenAI’s multilingual Whisper model. People on the same network can use a phone or computer browser to search the local library and add songs to a shared queue. Playback controls include pitch and tempo changes, seeking, and audio and subtitle delay. The display can be sent to a TV by HDMI or screen sharing, or viewed in a browser through an HTTP stream. Setup requires Python dependencies, VLC, and ffmpeg. Existing songs remain accessible offline, but internet search and new downloads do not. The project uses GPL-3.0, and its releases page lists no releases.
