Build a world of sound and light.

QLab is the award-winning software that makes it simple to create rich multimedia designs for live performances and installations. From Broadway to Britain's West End, from Denver to Denmark, QLab is the tool of choice for many of the world's most prominent designers.

Simply powerful show control.

QLab allows you to control audio, video, and MIDI from a single workspace.

The basic version of QLab is free and provides a powerful audio playback environment. For advanced users, licenses are available to enhance the audio features, as well as to add video and MIDI functionality.

Designed to enable you, not get in your way.

QLab provides an intuitive environment for crafting your design. Organize your cues simply by dragging and dropping them. Want to add a new sound? Just drag it onto your workspace. Need to trim the head and tail of that cue? Just bring up the waveform editor and drag your start and end points. Want your video flipped horizontally and centered on the second projector? Click, drag, done. Cut and paste cues to new locations, new workspaces, or even external spreadsheets. Decide you didn't like that adjustment? No problem, you can undo anything.

Rigorously engineered for first-class performance.

Designed for precision, QLab provides playback control accurate to thousandths of a second. It uses Apple's low latency CoreAudio framework to ensure your audio plays instantly. QLab guarantees sample-accurate audio synchronization across all cues in your workspace. It synchronizes your video too. And by taking advantage of Apple's Quartz Composer technology, QLab allows you to completely customize video rendering in each cue, applying image filters and more.
