Audiophilio

New in 1.6: Shared Test Tracks — share the reference songs you use to judge your gear, resolved across the major streaming services and playable right in the app.

Audiophilio is the professional audio toolkit for the serious listener — a complete suite of measurement tools, room design, and system planning, engineered for iPhone, iPad, and Mac.

NOW IN 1.6: SHARED TEST TRACKS

Share the reference tracks you use to evaluate your gear — and discover everyone else's. Paste a link from any service and Audiophilio resolves it across Apple Music, Spotify, Tidal, Deezer, and Amazon Music automatically — and you can add Qobuz and YouTube links by hand — so anyone can open it in the app they already use.

Each share carries a "what to listen for" note, an optional timestamp, and test-attribute tags (soundstage, sub-bass, imaging, vocals, micro-detail, dynamics, and more). Tracks play right in the app: a 30-second preview for everyone, or the full track for Apple Music subscribers.

MEASURE

• SPL Meter — real-time sound pressure levels with A/B/C/Z weighting and peak hold • Real-Time Analyzer — 1/3-octave spectrum analysis, live • LUFS Meter — momentary, short-term, and integrated K-weighted loudness • Waterfall Plot — scrolling spectrogram with an interactive 3D view to spot room modes and decay • Spectrogram — 2D frequency map for resonances and flutter echo • Oscilloscope — live triggered waveform display • Frequency Response & PEQ — log-sweep measurement with up to 32 parametric EQ suggestions (peak, dip, high/low shelf); REW, MiniDSP, and Equalizer APO export • RT60 Measurement — reverberation time per octave band • Energy Time Curve — direct sound, reflections, and ITDG • Channel Balance — L/R level and timing offset • Impedance Analyzer — resonance sweep for Fs, port tuning, and driver behavior • THD+N Analyzer — distortion via frequency sweep, with a per-frequency harmonic profile (H2–H8) • Wow & Flutter Meter — turntable speed stability from a 3150 Hz test record, with peak/RMS deviation and a letter grade • Delay Finder — speaker-to-listener delay and distance • Polarity Checker — correct or reversed speaker wiring • Noise Generator — white, pink, and brown noise for burn-in and acoustics

Every measurement tool shows your active input device — your UMIK-1 or the built-in mic.

DIAGNOSE

System Diagnosis analyzes your RT60, channel balance, distortion, polarity, impedance, and early reflection data, then ranks every issue by severity with plain-English fixes. On Apple Intelligence devices (iOS 26+), on-device AI goes deeper — privately, without sending your data anywhere.

DESIGN & SET UP

• Room Designer — interactive 2D/3D room visualization with standing-wave heat maps, first reflection analysis, toe-in arcs, and room mode labels. LiDAR room scan on supported devices. • System Builder — document your full signal chain with flow diagrams. Export your component list as forum-friendly Markdown with one tap. • Turntable Setup Suite — tonearm alignment (Baerwald, Löfgren A, Stevenson) with a null-point diagram, tracking-force and anti-skate reference, and a setup checklist. • Ear Trainer — learn to identify frequencies by ear across all 31 ISO 1/3-octave bands, with a scored quiz mode.

CALCULATE

Eleven acoustic calculators: Room Modes, RT60 (Sabine), SBIR, First Reflection Point, Schroeder Frequency, Crossover, dB Converter, Ohm's Law, Speaker Distance, Cartridge Resonance, and Thiele-Small Parameters.
