    This sound meter is also known as sound level meter, decibel (dB) meter, noise meter, sound pressure level (SPL) meter and to help you measure & detect environmental noise.

    Specially "Decibel X" is one of very few sound meter apps on the market having highly reliable and pre-calibrated dBA measurements. It turns your device into a professional sound meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you ever suffered from the noise of the neighbors? Or how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all those right now.


    - Tested and verified accurate on many devices. The precision is matching with real SPL devices when calibrated
    - Frequency weighting filters: A, B, C, Z
    - Beautiful, intuitive and carefully crafted UI design
    - FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed.
    - WAVE graph in real time


    - Time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds)
    - Trimming calibration from -20 dB to 20 dB
    - Standard measurement range from 30 to 130 dBA
    - HISTO graph for plotted history of the recorded values
    - Real time scale level chart
    - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layout
    - Quick reference text to help you compare with real-life examples
    - Record and export the data (up to 24 hours) to email for further analysis
    - Reset and clear all data at any time
    - Tap on Max value to reset at any time
    - Pause/Resume the tool at any time


    - Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA.

    - Because there are wide range of devices which have different microphone sensitivity, custom calibration is highly recommend before use. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.

    Two clicks from download to measuring sound levels. Literally, two. That's cool.

    Works well. Very good for RWC testing, as a guide to noise.
