About Audiophilio
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.
The Story
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.
What's New in 1.6
Version 1.6 introduces 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 you can add 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 — making the feed filterable by exactly the thing you’re trying to assess.
Tracks play right in the app: a 30-second preview for everyone, or the full track for Apple Music subscribers, complete with scrub and skip transport controls. When several listeners recommend the same song, their submissions group into a single card that pools everyone’s service links and test attributes. The release also rebuilds the Social tab to match the Tools tab’s clean, described layout, and hardens every microphone-based tool against rare audio-engine crashes.
Recent Releases
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.
Version 1.4 introduced the Ear Trainer — a tool for learning to identify frequencies by ear, with reference tones across all 31 ISO 1/3-octave bands and a scored quiz mode — alongside community discovery: acoustic grade badges, measurement chips, and sorting and filtering of shared rooms.
Version 1.3 introduced System Diagnosis — a feature that analyzes your measurement data and tells you what's actually wrong with your system. The rule-based engine evaluates RT60, channel balance, THD+N, polarity, impedance, and early reflection data, ranking every issue by severity with plain-English recommendations. On devices with Apple Intelligence (iOS 26+), on-device AI provides deeper explanations and more specific guidance — privately, without sending data anywhere. 1.3 also added an active microphone indicator to every measurement tool and forum-friendly Markdown export for system builds.

- Channel Balance — L/R level balance and timing offset measurement
- Impedance Analyzer — Speaker impedance curve with Fs and resonance peak detection
- THD+N Analyzer — Harmonic distortion and rattle detection via frequency sweep, with a per-frequency harmonic profile (H2–H8) distinguishing even- from odd-order distortion
- Delay Finder — Arrival time offset measurement between speakers
- Polarity Checker — Verify absolute polarity of any driver or system
- LUFS Meter — Broadcast-standard loudness per EBU R 128 / BS.1770-4; momentary, short-term, and integrated loudness with streaming platform targets
- Waterfall Plot — Time-frequency decay visualization; 31-band ISO 1/3-octave heat map with an interactive 3D view
- Spectrogram — 2D real-time frequency map for resonances and flutter echo
- Oscilloscope — Live triggered waveform display with adjustable time scale and gain
- Wow & Flutter Meter — Turntable speed-stability measurement from a 3150 Hz test record; peak and RMS deviation with a letter-grade result
- 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; reference tones across all 31 ISO 1/3-octave bands (free) plus a scored quiz mode
- Active Mic Indicator — Every measurement tool displays the active input device name, distinguishing between calibrated external microphones and the built-in mic
- Calibrated Microphone Support — Import REW/MiniDSP calibration files; level trim for device-specific offset correction
- Room Designer — 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
- System Builder — Visual signal chain diagramming from source to speaker; export as PNG, JPEG, PDF, CSV, JSON, or forum-friendly Markdown
- Acoustic Calculators (Free) — Room Modes, RT60, SBIR, First Reflection Point, Schroeder Frequency, Crossover, dB Converter, Ohm's Law, Cartridge Resonance, Speaker Distance, Thiele-Small Parameters
- iCloud Sync — Rooms and systems sync privately across all Apple devices via CloudKit
- Shared Test Tracks — 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
- Community — Share room layouts and system builds publicly; browse how other audiophiles listen. Facebook group for discussion and feedback.

Privacy
Audiophilio processes microphone audio entirely on-device. No audio is ever recorded or transmitted. System Diagnosis — including any AI interpretation — runs 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.
