Decibel: Sound Level Meter

Sound Meter is a powerful decibel (dB) measurement tool designed to accurately measure and analyze the sound levels around you. It's ideal for both everyday use and more detailed sound analysis needs. Key Features: Real-Time Measurement: Instantly see current, average (AVG), and maximum (MAX) decibel (dB) values. Detailed Analysis Graphs: Decibel History: Track changes in sound levels over time. Waveform: Visualize the raw shape of the sound. Frequency Spectrum (FFT): Analyze which frequencies the sound is concentrated in. Octave Bands: Perform frequency analysis in standard 1/1 and detailed 1/3 octave bands. Better viewing with full-screen landscape mode support! Advanced Settings: Frequency Weighting: Choose from A-Weighting (dBA) for measurements closest to human ear perception, C-Weighting (dBC) for high sound levels, Z-Weighting (dBZ) for unfiltered analysis, and ITU-R 468. Time Weighting: Select FAST (125ms) for quick response or SLOW (1000ms) for smoother readings. FFT Size: Balance time and frequency resolution with different FFT window sizes (1024, 2048, 4096). Precise Calibration: Calibrate your device against a known sound source for more accurate results. Multiple Microphone Support: Take measurements using your device's built-in microphone, your Bluetooth microphone, or your wired headset's microphone. Measurement History: Save your important measurements and review them later. User-Friendly Interface: An easy-to-use and modern experience with dark mode and dynamic color options. Reference Values: Easily compare the measured sound level with common sound sources (whisper, conversation, traffic noise, etc.). Take control of noise levels, analyze the sound environment in your workplace or home, or simply explore the world of sound around you with Sound Meter!
