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.
