WHY SOUNDMETER

Most sound meter apps are cluttered with ads, lock features behind paywalls, or display unreliable readings. SoundMeter combines laboratory-grade audio processing with a clean, professional instrument interface — and it costs nothing. Every feature is free, forever.

KEY FEATURES

Real-Time Decibel Measurement
See your current sound level displayed on a beautiful arc gauge with animated needle. Watch MIN, AVG, and MAX values update live, with peak hold to catch sudden spikes.

Waveform & Spectrum Visualization
Toggle between time-domain waveform and frequency-domain spectrum views. Identify noise sources — is it low-frequency rumble or high-pitched whine? The FFT-powered spectrum analyzer shows you exactly where the sound energy is.

Measurement History
Every measurement is saved automatically with timestamps. Review past recordings, compare levels across different locations, and track noise trends over time. Store up to 1,000 records on-device.

Noise Level Reference Guide
Built-in reference table with 8 noise levels — from whisper-quiet library (30 dB) to jet engine (130 dB). Instantly understand what your reading means in real-world terms.

A/C Frequency Weighting
Choose between A-weighted (human hearing) and C-weighted (flat response) measurement modes for different use cases.

Dark Mode & Customization
Full dark and light mode support with automatic system theme matching. Adjust refresh rate for battery optimization.
