Waves | - A Dribbble client | Reactive Programming library

I am trying to generate and draw a sin waves. I am using this formulae that I found online y = Amp * sin(2 * PI * frequency * time + shift)

I uploaded my code and svgs to this github repo.

I have some svgs of some circles, blobs and triangles. I am trying to make the circles shake, like how the guy shakes in this code pen when you hover on him, I am trying to make the blobs move like waves like in this code pen, and I'm trying to make the triangles spin around. The blobs and triangles are not responding at all, even though I can see that they have the styling applied when I inspect the html. The circles have some effect, but not the one I want.

Here is the code for each

I am currently trying to make a .wav file that will play sos in morse.

The way I went about this is: I have a byte array that contains one wave of a beep. I then repeated that until I had the desired length. After that I inserted those bytes into a new array and put bytes containing 00 (in hexadecimal) to separate the beeps.

If I add 1 beep to a WAVE file, it creates the file correctly (i.e. I get a beep of the desired length). Here is a picture of the waves zoomed in (I opened the file in Audacity): And here is a picture of the entire wave part:

The problem now is that when I add a second beep, the second one becomes completely distorted: So this is what the entire file looks like now:

If I add another beep, it will be the correct beep again, If I add yet another beep it's going to be distorted again, etc. So basically, every other wave is distorted.

Does anyone know why this happens?

Here is a link to a .txt file I generated containing the the audio data of the wave file I created: byteTest19.txt

And here is a lint to a .txt file that I generated using file format.info that is a hexadecimal representation of the bytes in the .wav file I generated containing 5 beeps (with two of them, the even beeps being distorted): test3.txt

You can tell when a new beep starts because it is preceded by a lot of 00's.

As far as I can see, the bytes of the second beep does not differ from the first one, which is why I am asking this question.

If anyone knows why this happens, please help me. If you need more information, don't hesitate to ask. I hope I explained well what I'm doing, if not, that's my bad.

EDIT Here is my code:

Can anyone explain how to create this waves

This is the code I have written in my home.dart file.

I need to render moving audio waveform like iOS voice memo app. Here I maintain waveform:[Int] rms amplitude of waves. Now when new waves come add it in waveform[Int] and I add new UIBezierPath line at right of CAShapeLayer and translate whole CAShapeLayer by 5 points.

But translation animation is not so smooth. Could you please suggest any better approach for it?

My current implementation:

I'm playing around with bs4 and I tried to scrape the following website:https://pythonbasics.org/selenium-get-html/ and I wanted to remove all of the script tags from html.

To remove script tags I used functions like:

I have 1024 samples and I want to cut them into 32 chunks of 32 and run FFT on each one of them and plot it via a Frequency-Amplitude spectrum, I have most of the code working just the part of applying FFT to each chunk is not working, however I am able to apply FFT to the whole samples array.

I tried doing something like that:

I am trying to send an email from a webpage but when i click on the submit button php code is opening. I have installed apache server and its up and running. I am not quite sure what i am missing and how to send an email from webpage. do i need to install sendmail and php also to make it work in local using apache server. below is my code. please help
