QLab

QLab is a macOS application for designing and playing back sound, video, lighting, and show‑control cues. Users create cue sequences that trigger media files, adjust parameters, and synchronize elements for live performances, installations, or rehearsals. The software supports spatial audio through object audio, allowing precise placement of sound sources within a venue.

The tool is aimed at theatre technicians, concert producers, multimedia artists, and any professionals who need to coordinate audiovisual elements during a show. Its cue‑based workflow lets operators cue media, control lighting rigs, and manage video playback from a single interface, reducing the need for separate control systems.

Developed by Figure 53, a small team of engineers and artists, QLab emphasizes reliability and user‑friendly operation on macOS. It is released as a stable product and receives regular updates, including recent enhancements to object‑audio handling.
