Description:

"Decibel X" is a highly reliable and accurate noise meter app that sets itself apart from others on the market. With pre-calibrated measurements and support for dBA and dBC, this app transforms your iOS device into a professional sound level meter, providing precise measurements of sound pressure levels (SPL) in your surroundings. Not only is this tool extremely useful, but it also offers an aesthetically pleasing design.

One of the standout features of "Decibel X" is its trusted accuracy. The app has been thoroughly tested and pre-calibrated for all Apple devices, ensuring its precision matches that of real SPL devices. Additionally, it offers Apple Watch support, allowing you to monitor noise levels directly from your wrist. Integration with the Health App also allows you to export noise level data effortlessly.

The app provides various frequency weighting filters, including ITU-R 468, A, B, C, and Z. These filters are essential for frequency analysis and musical tests. "Decibel X" also offers powerful history data management, allowing you to record and save data for future access and analysis. Each record can be exported as a high-resolution PNG graph or CSV text for easy sharing and comparison.

The inclusion of dosimeter features, such as NIOSH and OSHA standards, makes "Decibel X" a comprehensive tool for professional use. The app offers powerful calibration options, including Linear, Octave 1/1, 1/3, and the ability to load/save profiles.

Real-time FFT and BAR graphs provide visual representations of frequency analysis, while the InstaDecibel feature allows you to capture dB reports overlaid on photos for easy sharing on popular social networks. The app supports both portrait and landscape layouts and features a beautiful and intuitive UI design with three theme options: LIGHT, DARK, and CLASSIC.

In addition to its standout features, "Decibel X" also offers standard time weightings (Response Time) and the ability to adjust MIC Gain Offset. The measurement range spans from 30 dBA up to 130 dBA, and the app provides helpful graphs such as HISTO, WAVE, and SPECTROGRAPH for tracking and analyzing recorded values. Current, average/Leq, and max values are clearly displayed in digital and analog layouts.

It is important to note that quiet room readings may not reach 0 dBA, as the standard usable range is between 30-130 dBA. For serious purposes requiring higher precision, custom calibration is recommended. The app provides guidance on how to perform calibration using a real external device or calibrated sound meter as a reference.
