Everything you need to write about Audiophilio. Questions not answered here? Reach out directly.
Audiophilio is a professional audio toolkit for iPhone, iPad, and Mac, designed for audiophiles, home theater enthusiasts, and anyone serious about getting the best sound from their listening space. It brings together a comprehensive suite of precision measurement tools, an auto-diagnosis engine, a full room designer with acoustic analysis, and a signal chain planner — all in a single, focused app.
The app is free to download with a one-time in-app purchase to unlock the complete premium toolset. There are no subscriptions. Your data lives on your device and in your own private iCloud — Audiophilio collects nothing.
Audiophilio was built out of frustration. The tools audiophiles actually need — an SPL meter, a real-time analyzer, a proper room designer — were scattered across a dozen different apps, most of them ugly, none of them connected. The goal was to build the app that should have existed all along: one beautiful, comprehensive toolkit built specifically for Apple devices, with the care and attention to detail that audiophiles expect from the gear on their racks.
Version 1.8 introduces System Intelligence. Tap Analyze on any saved system in the System Builder and Audiophilio reads the entire signal chain — flagging a missing phono stage, speakers with no amplifier, a source that bypasses the DAC, out-of-range cartridge/tonearm resonance, and amp/speaker impedance and headroom mismatches — each ranked critical, moderate, or minor with a specific fix. Link a room and the advice becomes size- and treatment-aware. On devices with Apple Intelligence, an on-device model summarizes the findings in plain language — privately, with nothing sent anywhere.
Point releases have deepened it since: 1.8.1 added connection-aware routing checks and cartridge/tonearm and amp/speaker matching, plus a “Looking Good” section that affirms what a system already gets right. 1.8.3 adds a first-launch guided measurement that walks new users through their first reading, and restores automatic cross-service resolution when sharing a track to the community feed.
Version 1.7 gave the Ear Trainer a plain-language descriptor and a “listen for” tip for every one of the 31 ISO 1/3-octave bands, added an Essentials / All filter to streamline the Tools tab, and introduced community safety tools — report and block, content hidden immediately and reviewed within 24 hours, and Community Guidelines shown before you create a profile.
Version 1.6 introduced Shared Test Tracks — a community feed for the reference recordings audiophiles use to evaluate their gear. Share a track from any service and Audiophilio resolves it across Apple Music, Spotify, Tidal, Deezer, and Amazon Music automatically, with optional Qobuz and YouTube links by hand; each share carries a “what to listen for” note, an optional timestamp, and filterable test-attribute tags, and tracks play right in the app.
Version 1.5 brought two new tools for turntable owners — the Turntable Setup Suite (tonearm geometry for Baerwald, Löfgren A, and Stevenson alignment, with a visual null-point diagram and a step-by-step setup checklist) and a Wow & Flutter meter for speed stability — plus an interactive 3D Waterfall view, REW measurement import/export, high/low-shelf PEQ filters (up to 32 bands), a per-frequency harmonic profile (H2–H8) in the THD+N Analyzer, and full Dynamic Type support.
Analyzes a saved system's signal chain — missing phono stage, unamplified speakers, DAC bypass, cartridge/tonearm resonance, amp/speaker impedance and headroom — ranked with specific fixes; room-aware, with an on-device Apple Intelligence summary on iOS 26+.
Analyzes all saved measurement data and ranks issues by severity (critical, moderate, minor) with plain-English findings and recommended fixes. Enhanced by on-device Apple Intelligence on iOS 26+ devices.
Real-time sound pressure level with A, B, C, and Z weighting, peak and min hold, session recording with CSV export, and level trim calibration workflow.
High-resolution 1/3-octave frequency spectrum analysis.
Log-sweep room and speaker magnitude curve with up to 32 parametric EQ filters (peak, dip, and high/low shelf); import and export REW measurements, plus MiniDSP and Equalizer APO filter export.
Per-octave-band reverberation time via log sweep.
Room impulse response via Farina log sweep; direct sound, ITDG, and early reflections annotated on a 0–300 ms plot.
L/R level balance and timing offset measurement.
Speaker impedance curve with Fs and resonance peak detection.
Harmonic distortion and rattle detection via frequency sweep, with a per-frequency harmonic profile (H2–H8) distinguishing even- from odd-order distortion.
Arrival time offset measurement between speakers.
Verify absolute polarity of any driver or system.
Broadcast-standard loudness per EBU R 128 / BS.1770-4; momentary, short-term, and integrated loudness with streaming platform targets.
Time-frequency decay visualization; 31-band ISO 1/3-octave heat map with an interactive 3D view.
2D real-time frequency map for resonances and flutter echo.
Live triggered waveform display with adjustable time scale and gain.
Turntable speed-stability measurement from a 3150 Hz test record; peak and RMS deviation with a letter-grade result.
Tonearm alignment (Baerwald, Löfgren A, Stevenson) with a null-point diagram, tracking-force and anti-skate reference, and a setup checklist.
Learn to identify frequencies by ear; reference tones across all 31 ISO 1/3-octave bands (free) plus a scored quiz mode.
Every measurement tool displays the active input device name, distinguishing between calibrated external microphones and the built-in mic.
Import REW/MiniDSP calibration files; level trim for device-specific offset correction.
Interactive 3D/2D room layout with acoustic overlays: standing-wave heat maps, first reflection analysis, toe-in arcs, room mode labels, and snap-to-grid editing. LiDAR Room Scan on supported devices.
Visual signal chain diagramming from source to speaker; export as PNG, JPEG, PDF, CSV, JSON, or forum-friendly Markdown.
Room Modes, RT60, SBIR, First Reflection Point, Schroeder Frequency, Crossover, dB Converter, Ohm's Law, Cartridge Resonance, Speaker Distance, Thiele-Small Parameters.
Rooms and systems sync privately across all Apple devices via CloudKit.
A community feed of reference tracks for evaluating gear; resolves links across Apple Music, Spotify, Tidal, Deezer, and Amazon Music (plus optional manual Qobuz and YouTube), with what-to-listen-for notes, test-attribute tags, and in-app preview or full Apple Music playback.
Share room layouts and system builds publicly; browse how other audiophiles listen. Facebook group for discussion and feedback.
Audiophilio is free to download on the App Store. The free tier includes the SPL Meter, Noise Generator, Ear Trainer reference tones, all acoustic calculators, one room layout, one system build, and iCloud sync. The Premium unlock ($44.99, one-time) unlocks every measurement tool, the vinyl suite (Turntable Setup and Wow & Flutter), System Intelligence, System Diagnosis, unlimited rooms and systems, and all advanced acoustic overlays. No subscriptions. No recurring fees.
Audiophilio processes microphone audio entirely on-device. No audio is ever recorded or transmitted. System Intelligence and System Diagnosis — including any AI interpretation — run entirely on-device using Apple Intelligence; no measurement data leaves the device. User-created content is stored locally via SwiftData and synced only to the user's own private iCloud account. Audiophilio collects no analytics, uses no third-party SDKs, and has no servers of its own.
