LiveSpec is the audio analyzer you can carry into any room. Point it at a stage, a sanctuary, or a stream feed and see exactly what is happening, then fix it with confidence. Whether you tune arenas for a living or run the board at church on Sunday, the tools are the same and they are all included. RUN THE SHOW Real time analyzer with sharp, smooth traces and a 3D view that shows how the spectrum moves. Spectrograph that unfolds your sound over time, so feedback and rumble have nowhere to hide. SPL monitor with A and C weighting, LAeq and LCeq, a stoplight for your limit, and logging you can export to prove how loud the night really was. Dose meter with NIOSH and OSHA standards, so you know how much safe listening time is left. Live Mix plugin host that runs Audio Unit plugins on your stream or broadcast feed, with input and output meters and LUFS targets. Mix Balance targets that give your whole team one standard to mix to, every night. Auto EQ with Smart Listen that hears the mix and suggests the correction, then lets you shape it. TUNE THE SYSTEM Transfer function with phase and coherence, so you can trust what the trace tells you. Impulse response, delay finding, and speaker alignment, with multiple microphones averaged into one picture. Decay, waterfall, RT60, and harmonic distortion views when you need to look deeper.
