Components

Noise demo is a Noise sample application on android device written with Rxjava2 and Rupertz implementation of FFT. This app is an open source project, so it's free to use. Expect drag on most devices since rendering the FFT spectogram is not optimal. And it was so awesome and helpful. After trying this app, I want to try to find the "db Warning" feature to enable and set some options, and try to get the "Historys" feature but I did not find it.

Proposal

Propose to the developer of the Noise Demo app to add the "db Warning" feature and the "Historys" feature in the main display section of the Noise Demo app, and the developer should modify the main display section to add some features when the user enables the "db Warning" feature. Developers must also add a list of Historys that have been done by users to test noise samples on their android device.

Mockups / Examples

An example of a visible illustration image, after the developer added a feature I suggested in the main view.

Benefits

db Warning is a very useful feature for users, because the user will be warned when the current db value is larger when preset db value. Users can also enable the feature to set or set db Warning value, enable Vibrate to get notification when the current db value is larger than preset db value, user can also enable voice notification when db value is larger. And it's very useful, users can also find a list of Historys ever done to test Noise samples, and can choose to open and delete from Historys list. So users feel very happy because of the presence of these features, and will provide the best ranking for the application Noise Demo. And that's amazing.
