## What is ALauris?

ALauris is a sound level meter built by ALgruppe, an acoustic consulting firm, for its own field work. It shows not only how loud a sound is, but how loud it is at each frequency — on one screen.

■ Real-time measurement
• dB(A), dB(C) and dB(Z) side by side
• FAST (125 ms) / SLOW (1 s) time weighting, with MAX hold
• Display modes: Real-time, Leq, L10, L50, L90 (1–120 s analysis window)
• OVER warning when the input clips

■ Frequency analysis
• Spectrum with 1/3, 1/6, 1/12 or 1/24 octave smoothing
• Octave bands: 1/1, 1/3, 1/6 or 1/12 octave
• Spectrogram: 5, 10, 30 or 60 seconds
• FFT size 1024–16384, zoom and pan, read values with a cursor

■ Calibration and external mics
• Quick calibration with a 94 dB calibrator, with calibration history
• USB measurement mics and audio interfaces — each input keeps its own calibration
• Import microphone correction files (frequency–dB)
• On Mac, choose the input device and channel directly

■ Logging and reports
• A 1-second Leq log builds up automatically while measuring
• Noise dose: Korea OSH Act, OSHA and NIOSH criteria
• Alerts when a threshold level is exceeded
• Background noise rating: NC and NR
• Export to CSV and PDF

■ Themes and devices
• Five purpose-built themes: Studio (analysis), Analog (needle meter), Field (logging), Report (statistics), Calm (plain-language guide)
• Light and Dark modes
• iPhone, iPad and Mac — on Mac, measuring continues in the menu bar after you close the window
• Built-in user guide in English and Korean

■ Privacy
Sound from the microphone is used only on your device to calculate levels; it is never recorded, stored or transmitted. No personal data is collected, and there are no ads or trackers.

■ Please note
ALauris is not a certified IEC 61672 sound level meter; readings are for reference only. Smartphone microphones vary, so calibration is recommended. Noise dose values must not be used for legal or medical decisions.
