## Decibel Description
Decibel turns your device into a powerful sound level meter without any extra hardware. Measure ambient noise in real time, monitor sound levels (dB), and explore frequencies with the built-in Spectrum Analyzer. Capture reliable sound and noise data wherever you are.

Designed for casual users, audio enthusiasts, and sound engineers, Decibel works as a portable sound meter for quick sound checks or deeper audio analysis. Use it to easily check noise levels, test room acoustics, monitor workplace noise, or fine-tune audio equipment. Decibel has various advanced features, including saving and exporting noise measurement data, live sound level overlays for photos and videos, and exporting data to the Health app to track noise exposure over time.

“The best way to meter sound levels” — AppAdvice

SLEEP TRACKING AND SOUND RECOGNITION
Decibel’s sleep tracking and smart sound recognition help you understand your sleep environment and nighttime noise. While sleep tracking is active, the app can detect common sleep sounds such as snoring, coughing, talking, and other household or environmental noise that may affect sleep quality.

Each detected sound appears on a detailed sleep timeline, so you can see exactly when disruptions occurred and play back the related audio. This makes it easier to identify snoring patterns, sleep disturbances, and noise events that impact your rest.

All sleep sound recognition and audio analysis are performed entirely on your device using advanced on-device machine learning. Recordings stay private, are processed locally, and never leave your device.

- Sync with the Health app to track and export noise exposure data
- Add live sound level overlays to photos and videos
- Save sound measurements with location data and custom labels
- Record, store, export, and play back sound measurements
- Export sound and noise data in CSV or audio formats


SPECTRUM ANALYZER

## Decibel Reviews in United States

### ***** "Fine gift"
You can get me one opportunity for get my  website online to create app to government websites
-- €£Antonio£¥}}{}{}{, 2024-12-18

### ***** "Dr Patrick Corn"
Excellent app to balance the volume levels of my soundtracks.
-- PCotn, 2024-12-13

### *---- "It’s not what you are looking for"
Takes many steps before you actually get to the functionality. And when you thought it’s the end it tells you to buy expensive subscription
-- Jan625yu, 2024-11-29

### *---- "Stopped picking up audio"
Worked the first day then it stopped picking up audio. I checked that I granted permission to use the mic. No feedback from developer.
-- Hoevelmann, 2024-11-28

### ***** "Perfect quick reading"
Super fast and accurate reading
-- Jimmy$howtime, 2024-11-21

### *---- "NOT WORKING?"
This app has stoped working therefore I would appreciate a refund.
-- Rickinstein, 2024-11-13

### *---- "Not free"
Nothing like another paid app masquerading as a free app due to a “free trial”. Don’t get this app.
-- AtlasWanders143, 2024-11-08

### *---- "Guy, a subscription for a GUI for my microphone? Get lost"
The entire app is inundated with ads for their “premium subscription” since having the app for the last two hours, I’ve gotten two notifications about discounted subscription. 

Not everything needs a subscription and especially not this app. Get over yourselves.
-- Learn to edit yourself, 2024-10-29

### ***** "Much needed!"
I couldn’t find a db handheld analyzer via Reed or other online manufacturers.  Thankfully this program is able to capture frequency up to that 20k range.  Using this I have been able to pin point an annoying noise coming from one of our home appliances.
-- Quant_m.71, 2024-10-16

### ****- "Excessive paywall"
Great app! Hidden behind a 50$ paywall to make it useful again. Would I pay for full functionality? Sure. But 15, maybe 20. 50? No thank you.
-- mynicknameisalreadytaken, 2024-10-14
