WHY LIVESPEC Industry-standard measurement tools have historically meant expensive licenses, dongles, and Windows-only workflows. LiveSpec brings that rigor to a modern Apple stack with subscription pricing that makes professional audio analysis accessible on whatever device you have with you at FOH.

LiveSpec is made by LinearPhase — audio engineers building the tools we wished existed.
