NoiseCapture
New !:
If your smartphone is already calibrated, you can now calibrate other smartphones with the application, based on the ambient noise. Select Automatic Calibration in the Calibration menu, in "Transmitter" mode for the reference smartphone and "Receiver" mode for the smartphones to be calibrated. Approach the smartphones together and start calibration from the reference smartphone. The rest is automatic.
Features:
• Noise measurement and calculation of acoustic indicators (Leq, Lamin, LAmax, LA10, LA50, LA90...) on a journey
• Measurement description (text, photo, tags)
• Viewing measurements on a map
• Measurement history
• Smartphone calibration with a reference device
• Detailed help on using the application
Recommendations for the 'best' measurement (see Help for details):
• The smartphone should not be in the pocket but hand held
• The smartphone microphone should not be hidden
• The noise measurement must be carried out without adding noise!
• It is possible to use an external and calibrated microphone
Contribute to collaborative noise maps:
• Allow the transfer of measures into the community
• Realize mmeasurement outside buildings
• Do not measure when rainning or with wind
• Goto the collaborative noise map : http://noise-planet.org/map_noisecapture/index.html
Contribute to the NoiseCapture project:
• conttribute to the code development: https://github.com/Ifsttar/NoiseCapture
• share your comments, questions: https://github.com/Ifsttar/NoiseCapture/issues
• organize NoiseCapture Party to map your sound environment: http://noise-planet.org/
------------------------------------------------------
NoiseCapture App respects your private life:
• You fully control how the information is sent to the server
• Only anonymous data is transferred
• There are no audio recording: only acoustic indicators are calculated and transferred
• NoiseCapture App requires only strictly necessary permissions
Warning:
• Although NoiseCapture App is developed by specialists, keep in mind that a smartphone will never replace a professional sound meter. If you need advanced expertise, contact a professional.
• The quality of the measurement depends on the technical performance of your smartphone and its calibration. Depending on the nature of your phone and the version of Android used, it is possible that you can not measure with sufficient accuracy.
NoiseCapture App is the result of collaboration between two French research laboratories, the Laboratory of Environmental Acoustics (Ifsttar) and DECIDE team of Lab-STICC (CNRS), with a support from the European Commission.

My phone went black and would not turn back on after installing this app. Had to wait a few minutes for phone to work again. App does not work.... nothing happens when you press the record button. And map does not work.
I like this application!! congratulations. I have found that this is not simply tool but a community measuring the noise along Europe!!! Make it more visible! it could be great. I work in geomatics and the exportation to geo-json works fine. Some suggestions: Would it be possible to export the expectrogram as a raster to extract your own statistics?. Would it be possible, on the other hand, to save user-static measurements? Imagine we try to take indoor registration: the GPS is not going to work so the user stays fixed in a point for few second (a point with the mean/median value of dB per Hz is saved in a register/row), then he stops, walk to the next and repeats the operation. A unique geo.json or shp would be exported, the indoor coordinates would be added and shown in any other application, fugro viewer for example. I will continue playing.
Cute. Only it takes calibration. And that can be a pain because it requires specialized equipment. So this is not really a problem with the app, but this is something to consider if you plan on using the app. For me it is just a toy as I will probably not calibrate it.
We've been hearing a low hum for months at night that keeps us awake. This app is picking up the frequency and duration. I wish I could record a video of the spectrogram to be able to show as proof.
Tried to capture a 59Hz sound with that tool. Unfortunately it would not capture sounds below 63Hz, and there is no setting to change that.
top app for measuring noise. Very professional, not only shows db but a map of frequencies, and can be calibrated
Could it be possible with noisecapture android app, (or any other app,) to make a noise map with say 1 m resolution (or whatever GPS allows) in order to find (intermittent) sources of noise ?
This was amazing! I feel asleep with it on and all night long it recorded my heart beat!
Carefully designed, professional app that can be used by everyone as well! Congrats, development team!
Is there a possibility to make flexible scale for ultrasound? Up to 100kHz? Dogs can here high frequency and when they do they bark. I know that internal phone microphone supports frequency up to 20kHz but what if we connect external mic via 3.5 jack?
I need this to measure the time between two sounds, of course not an app on the appstore will do that.
Who ever is on this app is making my phone show up at my friend Mandy's house and a few more within a certain length . I have wittness to this, it don't show any of my vehicles in my yard but shows me on the Rd. Why is that? Can I get feed back
Little ive used pretty cool fun n interestin things your mind just doesnt notice on daily basis ya figure your ears at least have to notice
Is there anyway to download the recorded audio paired with GPS data? I want to be able to get the data onto my own computer.
Very useful for soundscape/noise mapping. Thanks.
It would not let me hit record. It would only freeze every time I tried
It seems to work well but I want to play the sounds for someone and I can't figure out how.
The issue was solved. Great work! And thanks for the response.
Tabs don't work and record doesn't start
Best Noise Capturing App I've Ever Used Would Recommend It To Anyone
Great app just need more room on my phone to keep it.
Map stopped working I would give 5 if it wasn't for that .
have to export all the results manually? is this 1995?
How can I write something that I can't even get to work on my phone I give up
i actually love it nice app
Thunder play with this town
Couldn't figure out
Is faulty. Asks for GPS all the time even though permission while in use has been given. Says no GPS even though GPS is on. Finds GPS after start noise measurement. Should find GPS after starting app to indicate status. Keyboard can not be easily closed by tapping on screen after entering noise measurement details. No confirmation that details have been transmitted. More measurement conditions like outdoor, inner or outer city, nature,
