Components

Noise demo is an application to test Noise samples on android devices, which are given from the microphone stream in real time, and it's amazing, but unfortunately, the developer does not add any other features in it. The application of noise demo is an open source project, so users of noise demo applications can provide suggestions and inputs to developers, therefore, I would like to propose new features to developers, so that noise demo applications are more interesting to use.

Proposal

I propose to the developer, to add the "Calibration" feature in the top toolbar section of the app view, the developer should modify the feature by providing calibration recommendations in it and adding the calibration icon at the top of the toolbar and providing usage instructions, using the feature.

Mockups / Examples

Here is an example of a visible image, if the developer has added the feature I proposed.

Benefits

With the "Calibration" feature in the Noise Demo app, users can adjust the sensitive microphone to measure the correct value, and that is a big and very useful thing, as well as with the presence of these features, the users will give excellent ratings to noise demo applications, and that's a big advantage. So users will tell other users and friends to download and install the demo noise app, and brag against them, because there is a "Calibration" feature in the app they use.
