Sound Analyzer vs Decibel X PRO: Sound Meter Usage & Stats

Sound Analyzer is an application for analyzing audio signals using only a mobile device. Its main function is to display frequency (Hz) and amplitude (dB) spectra in real time, but it can also be used to display changes in spectra over time (waterfall view) and to display waveforms (waveform view) at the same time. The frequency measurement accuracy of the Sound Analyzer is very high, and in a relatively low-noise environment, the measurement error is generally within 0.1 Hz. (when measured with default settings) Main Functions - Peak frequency display function (displays the frequency [Hz] and amplitude [dB] of prominent spectral components in real time) - Change of display range by touch operation - Switchable frequency axis scale between logarithmic and linear scale - Max hold function - Waterfall view (displays spectral changes over time) - Waveform view (displays sound waveforms) - Note display mode (displays pitch in terms of A to G♯ note names and error [cents]) - Screenshot function (with timer) - No advertisements About High Frequency Spectrum The app allows the highest frequency setting to be raised to 96 kHz, but settings above 22.05 kHz are primarily for high-performance devices, not for general-purpose devices. In most devices on the market today, data in the high frequency range above about 22 kHz is filtered out. Since it is not possible to acquire data in the removed range even with a higher setting value, it is normal for the spectrum in this range to contain only weak noise of less than -60 dB. However, depending on the model, larger noise due to filter processing may appear at certain frequencies such as 48 kHz and 96 kHz.

Decibel X PRO: Sound Meter

"Decibel X PRO" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your phone device into a professional noise meter, precisely measures the sound pressure level (SPL) all around you. 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 - Spectrum analyzer: 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. - Powerful, smart history data management: + 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 - Dosimeter: NIOSH, OSHA standards - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design OTHER FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) - Trimming calibration from -15 dB to 15 dB - Standard measurement range from 30 dBA up to 130 dBA - HISTO graph for plotted history of the recorded values - WAVE graph with 2 display modes: Rolling & Buffer - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording at any time - Pause/Resume at any time 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.
