## What is ARCQ SPL?

SPL Meter turns your iPhone or iPad into a precision sound pressure level meter for musicians, audio engineers, AV techs, and anyone who needs to know how loud it really is.

Built around real-time A- and C-weighted measurement, SPL Meter shows the readings the pros actually use — not a single number, but a full panel of simultaneous metrics.

MEASUREMENTS
• LAS / LCS — A- and C-weighted level with SLOW or FAST time weighting
• LAeq / LCeq — equivalent continuous level over your chosen averaging window
• LCpeak — true C-weighted peak, instant and max-hold
• TWA — time-weighted average for noise-exposure style monitoring
• Instant, average, and max-hold values side by side

LIVE SPECTRUM
• Real-time octave-band spectrum analyzer
• Drag across the display to read the level at any frequency
• Double-tap to expand for a full-screen view

FLEXIBLE INPUT
• Use the built-in microphone or any connected USB, Bluetooth, or headset input
• Multi-channel interfaces supported — pick the exact input channel
• A/B capture: freeze two readings and see the difference

DESIGNED FOR REAL WORK
• Choose your averaging window to suit the room and the source
• Custom thresholds and profiles
• Clean, high-contrast layout that reads at a glance on stage or in the field
• Universal — optimized for both iPhone and iPad

PRIVATE BY DESIGN
SPL Meter does all processing on-device. Audio is never recorded, saved, or transmitted. There are no accounts, no analytics, no tracking, and no ads.

A NOTE ON ACCURACY
Like any phone-based meter, readings depend on your device's microphone and are not a substitute for a calibrated Class 1/2 sound level meter for compliance work. SPL Meter is a powerful, consistent tool for monitoring, comparison, and setup — not a certified measurement instrument.
