## What is Decibel Meter?

Decibel Meter is a practical sound level tool for everyday environments. It helps you monitor ambient sound through your device microphone, understand whether your surroundings are quiet, comfortable, active, loud, or high-noise, and save key data from each measurement session.

Use it at home, in the office, in classrooms, dorms, study spaces, around equipment, near renovation work, or anywhere you want a clear reference for surrounding noise changes.

One purchase unlocks all features available in the current version, including measurement history, audio playback, scene photo records, and PDF reports.

Key Features:
- Real-time decibel readings: View the current ambient sound level in dB
- Spectrum analysis: Observe low, mid, and high frequency movement
- Environment status: See labels such as Quiet, Comfortable, Active, Loud, and High Noise
- Session statistics: Track average, minimum, peak value, and duration
- Measurement history: Save sessions for later review and comparison
- Audio playback: Save and replay audio from a measurement session
- Reading calibration: Adjust an offset for your device and reference source
- Decibel reference: Compare readings with common everyday sound scenes
- Scene photo records: Capture a scene photo with time, location, coordinates, and decibel data
- Photo archive: View, manage, and share generated scene record images inside the app
- PDF reports: Generate a report with a conclusion, data table, and decibel trend chart

Useful for:
- Checking sound levels at home, in offices, classrooms, dorms, and study spaces
- Recording renovation noise, machine sound, temporary noise, and other sound events
- Comparing sound changes across different times and locations
- Keeping scene records for later review, organization, and communication
- Staying aware of comfort during long exposure to louder environments

Important Note:
This app uses your device microphone, so readings may vary by device model, distance, obstruction, microphone condition, and surrounding environment. Measurements, scene photos, and reports are for everyday reference, record keeping, and communication only. This app does not replace a calibrated professional sound level meter and should not be used as medical, legal, or industrial safety evidence.

在家测孩子练琴音量，又能拍照又能回放录音，还能看频谱分析，比想象中实用。唯一希望以后能自定义报警阈值，不过目前已经够用。
