LiveSpec vs Audiolyze

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.

Transform your iPhone or iPad into a professional audio analysis workstation. Audiolyze delivers real-time spectrum analysis, waterfall spectrograms, and oscilloscope visualization with the precision tools you need for sound engineering, acoustic analysis, and audio production. SPECTRUM ANALYZER Visualize audio frequencies in real-time with a high-resolution FFT spectrum analyzer. Choose from multiple display modes (dB, Amplitude, Power) and trace styles (smooth spline curves, linear, or classic bars). Switch between logarithmic and linear frequency scales, and select from multiple constant-Q resolutions for RTA analysis, from 1 octave down to 1/24 octave precision. WATERFALL SPECTROGRAM Track how your audio evolves over time with a scrolling 2D spectrogram display. Capture up to 20 seconds of frequency history to identify temporal patterns, transients, and spectral changes that a standard analyzer would miss. OSCILLOSCOPE Examine waveforms in the time domain with a responsive oscilloscope view. Multiple trigger modes (rising edge, falling edge, auto, free-run) help you capture stable waveforms, with adjustable amplitude scaling and trigger threshold controls. HARMONIC ANALYSIS Automatically detect and display harmonics with intelligent fundamental frequency tracking. View overtone relationships, cent deviations, and harmonic order labels overlaid directly on the spectrum — valuable for tuning, voicing, and timbre analysis. SPL REFERENCE LEVELS View relative sound pressure level readings with a built-in SPL meter. Calibrate against an external reference meter to align readings, with optional Z-weighting (flat response) or A-weighting (human hearing curve). Provided for reference and comparison; not a substitute for a certified, type-approved sound level meter. ADVANCED SIGNAL PROCESSING - Multiple FFT sizes (512 to 4096 samples) - Selectable window functions: Hann, Blackman-Harris, Flat-Top - Configurable frame overlap (0-75%) for improved averaging - Rolling window and exponential smoothing modes - High-pass and low-pass filters with adjustable slopes (6/12/18 dB per octave) CUSTOMIZE YOUR WORKFLOW - Peak hold display with decay - Snapshot comparison for before/after analysis - Visual glow effects for enhanced readability - Sparse or dense grid overlays - Save and recall custom presets for each visualization mode FOR SOUND ENGINEERS & MUSICIANS Whether you're a sound engineer tuning a PA system, a musician analyzing instrument tone, a podcaster optimizing room acoustics, or an audio enthusiast exploring the science of sound, Audiolyze provides the analytical depth you need in a beautiful, intuitive interface. EVERYTHING UNLOCKED Every feature is available from the moment you launch. No subscriptions, no in-app purchases, no paywalls, and no ads. Works on iPhone and iPad. Optimized for performance with GPU-accelerated Metal rendering. Available in 13 languages.
