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 six precision measurement tools, a full 3D 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.
Key Features
- SPL Meter — Real-time sound pressure level with A, C, and Z weighting, peak hold, and reference tone generation
- Real-Time Analyzer (RTA) — High-resolution frequency spectrum analysis with selectable octave bands
- Room Designer — Interactive 3D/2D room layout with acoustic overlays: standing-wave heat maps, first reflection analysis, toe-in arcs, room mode frequency labels, and snap-to-grid editing
- System Builder — Visual signal chain diagramming from source to speaker, with component management and connection mapping
- Calibrated Microphone Support — Works with any external USB, Lightning, or USB-C calibrated microphone for reference-grade measurement accuracy
- Impedance Analyzer — Speaker impedance measurement and curve visualization
- Distortion Analyzer — THD and harmonic distortion measurement
- Delay Finder — Arrival time offset measurement between speakers
- Polarity Checker — Verify correct absolute polarity of any driver or system
- iCloud Sync — Rooms and systems sync privately across all Apple devices
- Community — Optionally share room layouts and system builds with other users
Pricing
Audiophilio is free to download on the App Store. Core tools — including the SPL Meter, Real-Time Analyzer, one room layout, and one system build — are available at no cost. The Premium unlock ($44.99, one-time) removes all limits and unlocks the full measurement suite and all acoustic analysis overlays.
Privacy
Audiophilio processes microphone audio entirely on-device. No audio is ever recorded or transmitted. User-created content (room layouts, system builds) 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.
