Built with SwiftUI and Metal for native performance. SUBSCRIPTION TIERS • Live Mix — Mix analysis, spectrum, SPL monitoring • System Tune — Transfer function, room tuning, measurement suite • All Access — Everything, plus all future features Start with a 7-day free trial of the full app. Monthly and annual billing available. 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

A professional audio toolkit for live sound engineers. Audio Spectrum Pro is a complete measurement suite on your iPhone: spectrum analyzer, chromatic tuner, oscilloscope, loudness meter, test-signal generator, and RT60 reverberation time measurement. Everything in one app, with a dark interface built for the stage and the concert hall. SPECTRUM ANALYZER Real-time spectrum from 50 Hz to 16 kHz on a logarithmic scale. Automatic peak detection highlights problem frequencies instantly. The "EQ Suggestions" panel tells you which band to cut and by how many decibels - before feedback ever happens. CHROMATIC TUNER High-precision pitch detection accurate to hundredths of a cent. Supports guitar, bass, violin, viola, cello, ukulele, mandolin, banjo, and a chromatic mode. Adjustable A4 reference, capo support, and a noise gate to reject bleed from the PA. OSCILLOSCOPE Real-time waveform display for signal-integrity checks, phase inspection, and clipping detection. The first thing you reach for when something sounds wrong. LOUDNESS METER Simultaneous RMS and true-peak readout with a scrolling history graph (120 frames). Watch your average level and catch peak spikes before they slam your limiters. TEST-SIGNAL GENERATOR Pink noise, white noise, a logarithmic sine sweep (20 Hz to 20 kHz), or a fixed tone from 50 Hz to 8 kHz - all played through the speaker while the mic keeps analyzing. Tune PA systems, ring out monitor wedges, and find room resonances without a separate signal generator. RT60 REVERBERATION ANALYSIS Tap Start, make an impulse (a clap, a click, or a sine sweep) - the app records the decay, computes T20, and extrapolates RT60. Size up a room's acoustics in seconds and know whether they're working for you or against you. BUILT FOR THE FIELD - Mic gain control with the volume buttons - one hand, while the other stays on the console - Fully dark interface - readable under stage lighting, easy on your night vision - Landscape orientation - lay it on the meter bridge or a side table - Three interface languages: English, Russian, Ukrainian Microphone access is required. A speaker or headphones are needed to play test signals.
