Build a Little App That Tells Me Fundamental Frequency of the Recorded Sound-


I expect you are all okay.

I have a job for you.

There is an App called Spectroid, which you can test from here:

[login to view URL];hl=es_AR

What I need, is just a Little Java Android App, with an Android Studio format, with nothing more than a Text View, which shows the Fundamental Frequency of the Recorded Sound, as Spectroid does.

But, with no graphs, with no configuration, ... with nothing more than that Text View.

In order to achieve this desired result, you can use any of several "Fourier Transform" Libraries that there are out there, and One App (Android Studio Project) One Freelancer did trying to achieve the mentioned result, which you can download as the Attached File of the Project.

Fourier Transform is the Algorithm to get that Fundamental Frequency, being the Fundamental Frequency the Frequency with the Most Wider Amplitude or Volume at any given time.

The thing, is, it really needs to give the Correct Frequency, as Spectroid does; ... and also, with the same Real-Time Result.

This Real-Time Result needs to "refresh" (throw a new result), at least 100 Times a Second.

Both this conditions, should not be too difficult to achieve, anyway.


I'll expect your proposals.
