Clock Signal vs OpenHomeKaraoke

Clock Signal is a free emulator for running classic software on Linux and macOS without first having to learn the original machine or emulator controls. It supports systems including the BBC Micro, Apple II, Atari 2600, Commodore Vic-20, early Macintosh, MSX, Sega Master System and ZX Spectrum. When you provide disk, tape or ROM media, it can identify and configure a machine, issue the commands needed to start the software, and speed up loading where possible. It does not import or take ownership of your files. The emulator processes video signals such as composite video and generates audio at the emulated machine’s source rate before filtering it for host output. Its README gives typical audio latency as 5–10 ms; display latency depends on host hardware. It aims for cycle-accurate emulation, which it says it achieves in some cases. Acorn Archimedes, Commodore Amiga and early PC compatible emulation is less complete than for the other listed systems. A BIOS is required. The project is MIT licensed, with macOS releases using Cocoa and Metal and Linux builds available through Qt, OpenGL or SDL options.

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.
