LiveSpec vs BetterAudio

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 14 day free trial.

The room is the first loudspeaker. BetterAudio turns your iPhone or iPad into an acoustic measurement tool. Using the LiDAR scanner and the microphone together, it builds a 3D model of your listening space and tells you exactly where to place your speakers for the cleanest stereo image and the tightest bass. WHY ROOM PLACEMENT MATTERS Most of what you hear from a pair of speakers is your room, not the speakers. A 5-degree turn, twenty centimeters from a wall, the wrong seat position — any of these will smear imaging, exaggerate bass, and kill detail. Studios spend thousands on treatment for a reason. BetterAudio gives you the same starting point in a few minutes, for free. WHAT IT DOES • Captures a full 3D model of your room with Apple RoomPlan and LiDAR. • Records ambient noise and broadband acoustic energy through the mic during the scan. • Computes the optimal speaker positions using the proven 38% rule and equilateral-triangle geometry. • Identifies the first-reflection points on each side wall — the spots where you should put absorbers or diffusers. • Reports your noise floor, peak SPL, bass/treble energy balance, and an environment classification (quiet, moderate, noisy). • Renders an interactive 3D scene showing your walls, ceiling, floor grid, furniture, doors, and windows, plus the recommended L/R speakers, sweet spot, and listening triangle with exact distances. • Gives you plain-language recommendations: aspect-ratio warnings, low-ceiling alerts, bass-rumble flags, toe-in guidance, and treatment suggestions. 1. Tap BEGIN SCAN. 2. Walk slowly around the room. The app guides you with on-screen prompts ("MOVE CLOSER TO WALL", "SLOW DOWN"). 3. Tap END SCAN. 4. Read the analysis. Move your speakers and your seat. Listen to the difference. REQUIREMENTS • A device with a LiDAR scanner (iPhone 12 Pro / Pro Max and later Pro models, iPad Pro 2020 and later). • Microphone access (used only during scanning, never recorded to disk). • iOS 26 or later. PRIVACY The scan and the audio analysis run entirely on device. No room data, no audio, and no measurements ever leave your iPhone. Nothing is uploaded, nothing is shared, no account required. BetterAudio is a tool, not magic. It cannot replace acoustic treatment in a difficult room, and it does not perform full impulse-response measurement. What it does is take the most expensive variable in any audio chain — the room — and make its rules visible.
