Decibel X: dB, dBA Noise Meter App 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 - Frequency weighting filters: 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 - 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 with 2 display modes: Rolling & Buffer - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design - Optimized for iOS 11 OTHER GREAT 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 - 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 - Tap on Max value to reset at any time - Pause/Resume the tool at any time 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.

  • Don’t buy full version

    By Gwazulu
    As soon as I purchased the full version I started receiving google adds. I have not received any news from the developers so until this is resolved they receive no star rating. The free version worked so much better. I reserve the right to change my rating if this is solved. Bought from App Store.

    I’ve only bought one app. This will be the second. I like the music played correctly, Not over my neighbors. Some things need respect. Michael.

    Horrible app. Crashes in about two seconds of opening it.
  • What Have They Done?!

    Wowza! You guys just keep getting “gooder” and “gooder”!😂 I really like the enhancements you’ve added today in the V6.3.0 (3744) release, especially the pop up comparative SPL/DB referential data for the dynamic textual comparative level descriptions you already displayed in your very clean GUI! This continues to be my go-to quality of life tool of choice. One screenshot and you’re done in the following example: “Oh, my music is too loud?” (TAP TAP) “Me thinks not!”🤣 (Note: My app is calibrated as you recommend.) But for one thing, I would give this app 5 stars. It doesn’t seem logical that “Normal Conversation” would louder than a “Quiet Street”. Thanks a bunch! SkyPaw guys, mighty CRISPY!! 👍🏿
  • Ver 6.3.0 not so good. Immediately closes itself.

    Totally useless. Prior versions were GREAT. Why change?
