Amplify your audio experience.

System Intelligence goes deeper: connection-aware checks, room-matched advice, and cartridge, tonearm, amp, and speaker matching — so you know exactly what to tune next. Audiophilio is the professional audio toolkit for the serious listener — measurement tools, room design, and system planning for iPhone, iPad, and Mac. NEW: SYSTEM INTELLIGENCE Build your system in the app and tap Analyze. Audiophilio reads your signal chain and flags what's off — a missing phono stage, speakers with no amp, a source bypassing your DAC, a tonearm/cartridge resonance mismatch, amp/speaker impedance and headroom, and more — each ranked by severity with a specific fix, plus what your setup gets right. Link a room for size- and treatment-aware advice, plus a private on-device AI summary on Apple Intelligence devices. 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 for 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; 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 and port tuning • THD+N Analyzer — distortion via sweep, with a per-harmonic profile (H2–H8) • Wow & Flutter Meter — speed stability from a 3150 Hz test record, with peak/RMS deviation and a 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 — UMIK-1 or 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 — with deeper on-device AI analysis on Apple Intelligence devices. DESIGN & SET UP • Room Designer — interactive 2D/3D visualization with standing-wave heat maps, first-reflection analysis, toe-in arcs, and room-mode labels; LiDAR scan on supported devices. • System Builder — document your full signal chain with flow diagrams and run System Intelligence on it; export the component list as 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, each with a description of what you hear and a "listen for" tip, plus a scored quiz. 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. COMMUNITY Share your rooms and systems, browse how others listen, follow fellow listeners, and join the Audiophilio Facebook group. Shared Test Tracks: share the reference tracks you use to evaluate gear — with a "what to listen for" note, test-attribute tags (soundstage, sub-bass, imaging, vocals, dynamics, and more), and links to the services you use. Play in the app: a 30-second preview for everyone, or full tracks for Apple Music subscribers. PRICING Free: SPL Meter, Noise Generator, Ear Trainer tones, all calculators, one room, one system, iCloud sync, and community. Premium ($44.99, one-time): everything else — all measurement tools, the vinyl suite, System Diagnosis, System Intelligence, unlimited rooms and systems, advanced overlays, LiDAR scan, and export. No ads. No subscriptions. No tracking. Just the tools.

  • This app has not received enough ratings or reviews to display an overview.

This release fixes sharing a Test Track: You can now always share a track by hand when a pasted link can't be looked up automatically — the details form no longer gets stuck. Clearer messages when the link service is unavailable, with a direct path to entering the details yourself. More reliable handling of pasted streaming links.
