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

  • Great for Sunday morning sound levels

    By ~Texas Pete~
    I am always using this app on Sunday mornings when I’m running my church sound board. It’s a simple and effective decibel meter that allows me to check the overall sound volume during practice. I trust my ears and memory to get the volume level consistent, but using Decible X means even when I’m a little congested or off, the sound level will still be spot on. I don’t use it enough to pay for the app but I find it very useful. I’ve even used it to spot check volume levels at other events to test out how loud the sound really is. The kids also enjoy seeing how loud they can scream from time to time. 5 stars through and through.

    The app is high quality, even the free version. What I don’t like is how much personal information, including my precise location and the front and back camera. Im sure there is much more as well.
  • Stop looking, get this one.

  • TAKE OFF THE PAY WALL AT LEAST FOR LEGACY USERS

    I love this app so much and I used the FFT 8192 so much almost every day but after this new update I can not use the app to my desired purpose and I don’t think I will use this trash money wall app ever again and I will tell all of my friends to never use this app. At least for the pre-update users please give us some of the features back. Then I will use this app again. Now I have to buy a spectrometer instead of paying for this. I hate this new change and please change it back or give legacy users some appreciation and give us the features.
  • Scam trial only - MONTHLY RIP!

    This is not really free, but a crippled trial. If you want the all the ‘features’ boasted about you will be RIPPED OFF A MONTHLY SUBSCRIPTION FEE. Repeat- - Monthly Fee, not one time purchase.

    In a recent update, C frequency weighting has been locked behind the paywall. Just prior, it had been available on the free version. I was promised greatly improved performance, not reduction of features

    I’m a private investigator and needing this app specifically to record noise within a neighborhood to measure the levels from various residents, as my client is being unfairly targeted for noise ordinance violations. Love the video feature; however, is there a possibility of also having GPS coordinates stamped within photos/vids as well? That would be VERY helpful in our industry, to prove noise levels at various specific locations within neighborhoods and public areas. As of now, this is a great app for PIs, just unable to prove specific location where photo/vid was taken.
