The Audiophile's
Toolkit.

SPL Meter

Real-time sound pressure level measurement with peak hold, A/C/Z weighting filters, and built-in reference tone generation.

Real-Time Analyzer

High-resolution frequency spectrum analysis with selectable octave bands. See exactly what your room is doing to your sound.

Room Designer

Interactive 3D and 2D room visualization with acoustic overlays — standing-wave heat maps, first reflection analysis, toe-in arcs, and room mode labels. On supported iPhone and iPad Pro models, scan your room automatically with LiDAR.

System Builder

Map your entire signal chain from source to speaker. Add components, define connections, and export your diagram as a PNG, JPEG, or PDF to share with the world.

Waterfall Plot

Time-frequency decay visualization showing how your room's bass energy builds up and dies away. Choose a 2D heat map or an interactive 3D view (frequency × time × level) to identify problem frequencies and track the improvement from acoustic treatment over time.

LUFS Meter

Broadcast-standard loudness measurement per EBU R 128 and BS.1770-4. Momentary, short-term, and integrated loudness with true peak detection — essential for content creators and streaming-platform compliance.

Oscilloscope

Live triggered waveform display with adjustable time scale (1–50 ms/div) and gain. Locks to a stable cycle on periodic signals — useful for verifying tone purity, spotting speaker distortion, and observing room reflections.

Energy Time Curve

Measures the room impulse response via log sweep and FFT deconvolution. Displays the ETC (|h[n]|²) in dB vs. time — direct sound, early reflections, and ITDG clearly annotated. Shows what no RT60 number can.

Measurement Suite

A complete toolkit for the precision-minded audiophile: Impedance Analyzer, RT60 Measurement, Channel Balance, Delay Finder, and Polarity Checker. The Distortion Analyzer adds a per-frequency harmonic profile (H2–H8), separating euphonic even-order distortion from harsh odd-order. Supports calibrated external microphones for reference-grade accuracy.

The Frequency Response & PEQ tool goes further — measure your room or speaker with a log sweep, then let Audiophilio generate up to 32 parametric EQ filters (peak, dip, and high/low shelf) correcting toward Flat, Harman, House Curve, or a custom target. Import and export REW measurements, and export filters to REW, MiniDSP, or Equalizer APO.

Ear Trainer

Build one of the most valuable skills an audiophile can have: recognizing frequencies by ear. Reference mode (free) plays pure sine tones for all 31 ISO 1/3-octave frequencies — from 20 Hz sub-bass to 20 kHz air — organized by band so you can study them deliberately. Quiz mode challenges you to identify a randomly selected frequency from three choices, with Easy (octave bands) and Medium (full 1/3-octave) difficulty levels. Your best score is tracked across sessions.

Vinyl Tools

Set up your turntable like a pro. The Turntable Setup Suite calculates tonearm geometry for Baerwald, Löfgren A, and Stevenson alignment — with a visual null-point diagram, tracking-force and anti-skate reference, and a setup checklist. The Wow & Flutter meter measures speed stability from a 3150 Hz test record, reporting peak and RMS deviation with an A–F grade.

iCloud & Community

Your rooms and systems sync automatically and reliably across all your Apple devices using CloudKit — even in the background. Share your setups publicly and discover how other audiophiles listen.
