Audiophilio — The Audiophile's Toolkit

Everything you need

Built for the way
you listen.

From the listening room to the gear rack, Audiophilio puts professional-grade tools in your hands.

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. 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, Distortion Analyzer, RT60 Measurement, Channel Balance, Delay Finder, and Polarity Checker. 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 20 parametric EQ filter suggestions correcting toward Flat, Harman, House Curve, or a custom target curve you import. Export filters directly to REW, MiniDSP, or Equalizer APO.

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.
