Components

Chroma doze application is an application that can help sleep well with calming algorithm fourier analysis. Just sketch the user's favorite spectrum and listen to the resulting stream of white noise. Features No ads or weird permissions, Does not just play a looped sample, Relatively power-efficient, Runs in the background, Save your favorite sounds in the Memory list, Contains math, Open Source / Free Software (GPLv3 license).

Proposal

After installing the application chroma doze users can be able to help sleep well with calming algorithms of fourier analysis. Just sketch the user's favorite spectrum and listen to the resulting stream of white noise. As a user I propose to the developer to add the "Quality of microphone bandwidth" feature and the "measure the frequency response" feature in the settings section of the chroma doze application.

Mockups / Examples

This is a sample image after the developer added the "Quality of microphone bandwidth" feature and the "measure the frequency response" feature in the chroma doze application.

Benefits

With the Quality of Microphone feature the user's bandwidth can determine the total noise level and can be used as a spectrum analyzer for microphone signals. Users can specify the dynamic range of sounds there are different frequency bands so as to get more accurate results. And the user can input AFC calibration (calibration). To explain the unequal frequency response of the microphone and recording the line device. The measure the frequency response feature makes the user's android phone a professional audio analyzer. Supports 1, 1/2, and 1/3 octave filters. And it can display the overall peak and RMS acoustic measurement values ​​as well as identify tones and sounds. With these features the more interesting people to use chroma doze app. And this is a wonderful thing.
