Description

"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level 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 wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Health App integration: export noise levels directly into Health app - Frequency weighting filters: ITU-R 468, A, B, C, Z - 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 + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - Dosimeter with NIOSH, OSHA standards - Powerful calibration: Linear, Octave 1/1, 1/3, Load/save profile - 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. - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support Live Activity, Dynamic Island - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design. Themes: LIGHT, DARK and CLASSIC OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) AND IMPULSE (50 milliseconds) - MIC Gain Offset from -50 dB to 50 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 - SPECTROGRAPH - 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 NOTES: - 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. - Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. 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. * Privacy Policy: http://www.skypaw.com/decibelx/privacy_policy.html * EULA: http://www.skypaw.com/decibelx/terms.html

    well at least i could measure the decibel level to a centi-decibel with this bare bones app. the app utilizes the onboard microphone and possibly other measurement devices within the phone to report the decibel level of a test kitchen of noises to acclimate the observer to the decibel spectrum within an environment of study. we did not delve further into the additional interface functionality as per our zero investment in, zero investment out fiscal model. zero warranty on the flocks of out the box socks walks when the windows break. ifn you can, perhaps just some jam for the toast we eat in the italiano L’hopital. have you the time for the red hat wine builds of hax on the free? we slip knot clutch slam the kiss of the gear shift jam into perpetual three for five. i appreciate the app rewrites, sorry i cant even pay for a wife in this lovely fish bowl we have in the macOS test case. make sure to provide color wheel or sliders feel like a investment worth the trade of this money from the spring. supposed to pay for every mistake i continuously make when i find myself trying to think of something else other than their gaze from cyber far. if you run the bar, i came in car, just to clean the drip pans under their bell bottom. we goteem. so hot in the shade of their tree spread. dont lose your head, we will wind up wed in the late of September. because of my temper we can make fun of lepers of the gab. have you heard my gig? i geek the mil spec sig. from a hand of two bird, three rock. i could balk and hit the billboards in left field

    I’ve been using this app for many years and I’ve not had any issues with it until the last couple weeks. The app crashes on launch unless I completely un-install the app and re-install it. This goes for both my M4 iPad and my iPhone 13 Pro. Since I have been using Decibel X for so long, I use the “restore purchase” function to get my premium subscription back. Maybe this is related to the crashes? Devs please look into this because I love this app and I don’t want to find another one. Thank you! Have a wonderful day! :)

    After the recent update to a subscription model the app no longer launches after “restore purchase” confirmation. Been a longtime user, bought the pro version in 2018 and now it’s unusable-

  • Cool it with the pop ups

    Just what I needed to properly break-in my new speakers

  • Unusable if in a hurry, ads are insane

    Unusable, especiallyif you need a quick reading. Ads are overwhelming, and open app store while trying to get rid of them. Used to be a great app, was going to upgrade to rid myself of ads, but $70 is insane, especially if one doesn’t need the extra features & just want the intrusive ads to go away. Uninstalling

  • App opens the microphone and leaves it capturing in the background

    The app crashes immediately on startup. It originally launched just fine after startup, but subsequent times it crashes.

    I tried to open up the free version of it and it got stuck. It would not open it up so that I could use it without having to pay for it. It was very frustrating. I’m going to delete it again and try one more time.
