Jamulus

Jamulus enables musicians to perform, rehearse, or jam together in real time over the Internet using ordinary broadband connections. The software streams high‑quality, low‑latency audio so participants can stay in sync as if they were in the same room. It supports a range of ensembles—from choirs and rock bands to folk and classical groups—and is also used for remote music lessons in educational settings.

The application is free, open source, and distributed under the GPL, allowing anyone to download, run, and modify it on supported platforms such as macOS. Documentation, troubleshooting guides, and community forums are provided to help users set up sessions and resolve technical issues. Contributions to code, translation, or documentation are welcomed through the project’s contribution guidelines.

Jamulus is intended for musicians, educators, and hobbyists who need a low‑cost solution for collaborative music making across distances, offering a straightforward way to connect and play together online.
