Adding Firebase functionality in your app | Part 2 Creating Firebase Authentication

-
Introduction:
In this post, we will create a Login and Registration Page with Firebase authentication, we will accept the name, email, password of the user and register the user with the Firebase auth library.

Implementation:

  1. First, we need to enable authentication for our project, go to the Firebase console, select Authentication from the left panel and then sign-in method, enable email method.
  2. In AS, go-to the assistant, in the right panel, select Authentication, click connect to Firebase, it will be in green when connected, second select Add Authentication to the project, Accept changes and finish.
  3. Now you can start coding.
  4. Create an Empty Activity, named as SignUp
  5. Go to SignUp.xml and add the following XML.

The XML file defines three EditText for user input and Button.

Add the following java code to read the input and create an account with the Firebase


If everything is done correctly, you would be able to create an account with your email, when created check the Firebase console user section and you'll see a new account added.
Now let's implement Login Page

Create a new activity, named SignIn
Go to layout_signin.xml and add the following code:

Here we have created two input fields to accept email and password
Add the following java code in SignIn.java

Once, done you can view the Toast to see whether it works or not.
When you launch the app, you have to enter email and password every time to reduce that work, you can do the following in the first activity in your app, in my case, it is SignIn.java

Audio de-noising using Python (Wavelets)

-
What is audio de-noising? Audio de-nosing is a process of removing noise(unwanted sound/signals from audio). You might have heard of noise cancellation headphones, these remove all the noise from the audio.  This process has various applications in media creation and learning. Also, de-noising is not only done on audio but also done on images. There are various methods to do this. We will see 2 methods and implement one. Method 1: FFT (Fourier Transform)    There are multiple different implementations of FT: FFT (fast FT), STFT (Short time FT). Also, there are inverse for each of them IFT respectively. So what is it? In short, FFT converts signals from one form to another, in audio, the time-series signal is converted to the frequency domain. More shortly, the dominant audio (your voice) will have more power than the non-dominant(noise). The following video will explain (a really good video):  Denoising with FFT (in Python)  Method 2: Wavelets (faster than FT)    These are complicated

Using FFMPEG to trim your videos

-
 There are multiple methods to trim or clip videos with the help of FFMPEG, but sometimes looking at the documentation can confuse lots of us, and we cannot derive the output we want. And the examples on the documentation are simpler than what we want to do. So I will show few methods to combine, trim or clip video files using FFMPEG. I won't be going through installation process and will assume that you already have it installed. 1. Using timestamps to clip the video 🕐   ffmpeg -i video.mp4 -ss 00:00:00 -to 00:10:00 -c copy output.mp4   This command will copy the clip from 0 sec to 10 min without re-encoding, since we specify not to re-encode. Break down of command:      -i  : input video file     -ss : starting timestamp you can define in hh:mm:ss or just secs     -to : ending timestamp, this is the timestamp of the video     -c copy : codec is copy, which doesn't require re-encoding   If you want to copy the video from some other time to some duration    ffmpeg -ss 00
