LiveSpec vs Surviving Audio

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. Parametric and Graphic EQ with profiles that match the grid of popular consoles and processors, so what you design is what you can actually dial in. Signal generator with popular noise types, sweeps, and a playlist for your reference tracks. Setup wizard that finds your interface, checks your channels, and has you measuring in about a minute. MADE FOR THE JOB Works with the built in microphone or any USB audio interface, from a single mic to a full multichannel rig. Calibration files for your measurement microphones. Measurement configurations, targets, captures, and settings sync between your iPhone, iPad, and Mac through iCloud. Dark themes designed for a dim front of house position, with every panel readable at arm's length. ONE PLAN, EVERYTHING INCLUDED Start with a 7 day free trial.

Plan the show, before the show. Surviving Audio is the pre-show planning suite for working sound engineers. Built around real-world workflows from the live PA design playbook — McCarthy-grade math, dynamically visualized, with practical guides on every tool. The big six: Stereo PA Quick-Eval — Type room dimensions (W × D), get a complete system recommendation: speaker spacing, coverage range, throw distance, FAR/LAR, plus a class verdict (long-throw, standard, wide, multi-box). Answers "which system do I bring?" in 30 seconds. Multi-Tower Delay Chain — One tower? Five towers? The app calculates the position and electrical delay for every tower based on your venue depth and the 40 ms threshold (temperature-adjusted). Visualizes the entire chain with side-elevation diagram. Spatial Crossover — The exact position where main and delay tower meet at equal level, plus the delay setting in ms and samples. Includes a level-vs-position SPL plot showing the transition zone. Sub Setup Recommende — Number of subs + crossover frequency + stage width = the right configuration. Single, coupled, stereo (with power-alley warning), cardioid stack, end-fire, distributed, or coupled block. Each rendered as a top-down stage diagram with λ/2 reference. Cardioid + End-Fire Sub Designer — Calculate delays, polarity, and forward gain. Interactive polar plots at chosen frequency. Top-down layouts with dimensioned spacing. Line Array Splay (Field Estimate) — Rough estimation of splay angles using only a laser distance meter. Side-elevation showing progressively splayed boxes. Pre-MAPP/ArrayCalc reality check.
