dB Meter & Spectrum Analyzer vs AudioToolsMax

"The best way to meter sound levels" - AppAdvice Decibel Meter is full of features sound level meter with exclusive accuracy of measurements and integrated spectrum analyzer. Calibrated with professional dB meter. The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one? dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters. (Please note that dB Meter soundmeter app is not a replacement for professional devices and should be used for personal purposes only.) FEATURES: ● Health App integration. Export measured noise levels and audiogram directly to Health app. ● Noise dosimeter regarding NIOSH and OSHA standards ● Photo & video with the noise overlay ● Powerful hearing test ● Saves location data for each measurement. ● Save measurements with custom names and rename existing measurements. ● Export measurements in CSV or Audio format. ● Allows you to save, export and play back recorded measurements. ● Highly accurate measurements. ● Integrated Fully Functional Spectrum Analyzer ● Octave Band Real Time Analyzer ● FFT Plot (Fast Fourier Transform) ● Spectrogram ● Linear and logarithm scales ● Up to 16384 FFT size ● A lot of available window functions ● Tracking for max value ● Max and Min for any selected frequency ● Stunned graphics You can enable or disable noise levels data exporting to Health app in dB Meter Pro app settings.

AudioToolsMax is the complete professional audio test & measurement app with every tool completely unlocked and ready to use. Educational discounts are available under the Apple Educational Discount program. AudioToolsMax includes all of the additional optional modules, like SoundSource, SPL Graph, SPL Traffic Light, LARSA, Transfer Function, STIPA, Impulse Response, and more. It's the full package. We test every iOS device and calibrate the microphone level and frequency response for the best results. We have the ability to turn off the Apple low frequency filters, and on many devices we can measure up to 120 dB SPL. Add iTestMic, iPrecisionMic, or iAudioInterface2 for a complete professional audio and acoustic test and measurement platform. Actual reviews: “...AudioTools is a “how did I ever live without it” app”. “I think this application is the best I EVER purchased.” “I have used many thousands of dollars of complicated test equipment that doesn’t measure up to this app suite.” ***** Included in the app price ***** * SPL Meter A faithful reproduction of a classic analog SPL meter.
