Description
Turn your smartphone into a professional Sound Meter and Audio Analyzer!
Whether you are checking noise levels in your neighborhood, tuning a musical instrument, or just curious about the sounds around you, Sound Meter provides accurate real-time analysis with a stunning Neon interface.
Sound Meter is not just a standard decibel meter; it is a complete audio toolkit that visualizes sound in multiple ways using advanced FFT (Fast Fourier Transform) technology.
KEY FEATURES:
Precision Decibel Meter (dB): Get instant, accurate readings of ambient noise levels. Sound Meter calculates RMS (Root Mean Square) to provide a stable and reliable decibel reading that matches real-world sound pressure levels.
Live Frequency & Musical Note Detector: Unlike other meters, Sound Meter analyzes the pitch of the sound! • See the exact raw frequency in Hertz (Hz). • Identify musical notes (e.g., A4, C#5) in real-time – perfect for tuning guitars, pianos, or checking your voice pitch.
Professional Visualizations: Analyze sound with four distinct, high-performance graphs: • Analog Gauge: A classic needle-style meter with colored zones (Safe, Warning, Danger). • Digital Display: Large, easy-to-read neon text. • Waveform Graph: Watch how sound levels change over time. • Spectrum Analyzer: A real-time FFT bar graph showing the intensity of different frequencies (0Hz - 22kHz).
Advanced Calibration: Every microphone is different. Our exclusive Calibration Slider lets you manually adjust the sensitivity from -40dB to +40dB to match professional equipment.
Comprehensive Statistics: Track your session with live updates for: • Minimum (Min) • Average (Avg) • Maximum (Max) sound levels.
Modern Neon Aesthetics: Designed with a sleek dark mode and vibrant neon colors (Cyan, Purple, Pink, Green) that look amazing on any screen. The interface is responsive and easy to use.
PERFECT FOR: • Measuring environmental noise (neighbors, factories, traffic). • Tuning musical instruments. • Testing audio equipment. • Educational use (Physics of sound). • Protecting your hearing from loud environments.
Privacy First: We respect your privacy. Sound Meter requires microphone permission solely to process audio data in real-time. No audio is ever recorded, saved, or uploaded to any server.
Disclaimer: While Sound Meter allows for calibration, microphone quality varies by device. For critical professional safety measurements, please use certified hardware.
