Decibel X PRO: Sound Meter

The "Decibel X Pro" app is a powerful and accurate sound measurement tool that offers a variety of features to help users analyze and track sound levels. One of the key selling points of this app is its trusted accuracy, as it has been carefully tested and calibrated for most devices to ensure precision that matches with real SPL devices. This makes it a reliable tool for professionals and anyone who needs to measure sound levels with accuracy.

The app also offers a range of frequency weighting filters, including ITU-R 468, A, B, C, and Z, which can be useful for different types of sound analysis and testing. In addition, the spectrum analyzer feature provides real-time FFT and BAR graphs, making it easy to visualize and analyze frequency data. The app also displays the predominant frequency in real-time, providing even more detailed information for users.

One of the standout features of "Decibel X Pro" is its powerful and smart history data management. Users can save recording data into a list of history records for future access and analysis. These records can also be exported as high-resolution PNG graphs or CSV text files, making it easy to share and analyze data. The app also offers a fullscreen mode for a comprehensive overview of the entire history of a record.

In addition to its sound measurement capabilities, "Decibel X Pro" also includes a dosimeter feature that adheres to NIOSH and OSHA standards.

It supports both portrait and landscape layouts, making it convenient for users to use in any orientation. Other features of the app include standard time weightings, trimming calibration, a measurement range of 30 dBA to 130 dBA, and various graph displays for recorded values.

It's important to note that the app's usable range is 30 dBA to 130 dBA, and a reading of 0 dBA should not be expected in a quiet room.
