Noise Capture

Developer’s Description

Noise Capture
This program with GUI interface uses for capturing of audio stream from Skype VoIP program and its post-processing with Noise Cancellation filter for cleaning of initial voice in real-time mode. The program can clean a speech in outgoing audio stream and the incoming audio stream from the network. The program can save into file (*.wav) initial audio stream and audio stream after GritTec’s post-processing

NoiseCapture is a free and open-source Android application that allows users to measure and share the noise environment. Each noise measure is combined with its GPS track so that the result can be displayed in an interactive maps within the application, but also on this page.

NoiseCapture can be used by anyone with experience in the field of noise, allowing to carry out acoustic measurements in a certain respect of the rules of art and then to observe a sufficiently critical look at the results provided.

NoiseCapture: what kind of users ?

NoiseCapture is an application intended above all to a public having a level of technical expertise allowing to carry out acoustic measurements in a certain respect of the rules of art and then to give a sufficiently critical look at the results provided. The profile of the user can be very diverse, but in any case it should have a certain “sensitivity” in the field of noise in the environment: acoustician, technician or engineer (in the broad sense) within a community or a consulting firm, a technical training professional, or any person who has received preliminary training in the use of the application, for example during a NoiseCapture Party.
NoiseCapture can of course be of interest to a wider audience, bearing in mind the need to have a critical look at the results provided by the application.

Noise reducer is a tool for noise removal in audio files. Your recorded audio won’t be up to the mark if it’s noisy, so you need a good noise reducer app to hear it clear on your audio player. It’s the best noise reducer/cancellation app in the market by a great margin because it incorporates the latest Deep learning process to remove/cancel noise from an audio file.

It also features a sound recorder inside it along with the noise-reducing/canceling feature. It even lets you save your reduced audio in different formats like AAC, MP3, WAV. It’s something a perfect noise reduction/cancellation app must include in its features.

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.

• 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
