This extremely useful and beautiful tool will not only be an essential gadget for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel X PRO" will help you answer all of those.
WHAT MAKES "DECIBEL X PRO" SPECIAL:
- Trusted accuracy: the app is carefully tested and calibrated for most devices. The precision is matching with real SPL devices
- Frequency weighting filters: ITU-R 468, A, B, C, Z

+ Recording data can be saved into a list of history records for future access and analysis
+ Each record can be exported as hi-res PNG graph or CSV text via sharing services
+ Fullscreen mode to give overview the whole history of an record

NOTES:
- Please do not expect a quiet room reading will be 0 dBA. The range 30 dBA - 130 dBA is the standard usable range and an average quiet room will be about 30 dBA.
- Although most devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. To calibrate, you will need a real external device or calibrated sound meter as a reference, then adjust the trimming value until the reading matches with the reference.
