MuLab is a digital audio workstation application for macOS (OS X) and Windows platforms.

It is developed and maintained by a small company (MuTools, Belgium) led by Jo Langie, a pioneer in sequencer technology since early Atari microcomputers.

It may be also of interest for educational purposes to people learning digital audio processing.

MuLab has most of the features of a standard full DAW: audio/MIDI recording, MIDI sequencing, mixing, automation, control surface interaction, multi-core, stock synths, samplers and effects, multi-projects and templates, etc.

MuLab has an internal architecture built around a modular system (Mux) enabling customized instruments and effects by drawing graphs of modules.
