morse | Morse Code Library in Go | Messaging library

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:

I've been trying to write a program that takes a string as a input, and output will be the same string written in morse code, however in getting reading access violation, while using %s format specifier with *(mors + i).

I am trying to build a responsive gallery from this tutorial. And here is my attempt on codesandbox.io

Whatever I try there is one little problem. It looks nice but somewhere in half or after half only four columns are shown instead of 5 as shown in the image below:

I wrote a code which uses flutter_mobile_vision and morse to scan texts via mobile camera and covert those scanned texts into Morse code.
Here is my code:

I'm making my microcontroller display letters of the alphabet in Morse code using LEDS (dot == short blink, dash == long blink).

I could make a switch statement and do it like this :

dic = {"A" : ".-", "B" : "-...","C" : "-.-.","D" : ".","E" : "..-.","F" : "..-.","G" : "--.","H" :"....", "I" : "..", "J" : ".---", "K" : "-.-", "L" : ".-..", "M" : "--", "N" : "-.", "O" : "---", "P" : ".--.", "Q" : "--.-", "R" : ".-.", "S" : "...", "T" : "-", "U" : "..-", "V" : "...-", "W" : ".--", "X" : "-..-", "Y" : "-.--", "Z" : "--.."}

I have a school project where I need to make a morse to english transaltor. I'm a newbie when it comes to Java so I was wondering if you could assist me. The problem is that I'm unsure on what I'm supposed to put on the while loop to turn the morse code to english. Any help would be appreciated. Thanks^^

I have a project where I need to get an input from the user, convert that to morse code and vice versa.

I have to use a hashmap, and my code looks like this. It's not really working. I'm having trouble understanding how I can print the input I get from the user on the class engToMorse.

I tried to look through other similar questions as well, but I couldn't find anything that could solve my issue.

Edit 1: By changing .toLowerCase to .toUpperCase, it does work, but only for one word. How would i go about making it work for multiple words, like a sentence. Edit2: That was fixed by adding translator.put(' ', " ");. How would I go about converting morse to english now? It is the same idea?

I am working on a Morse Code encoding/ decoding tool. I have completed the encoder, and I'm working on the decoder. Currently the decoding function "MorseCodeDecoder(MSG)" can decode a single letter at a time. It does this by checking every character in a string one by one and copying them to the variable, "EncodedLetter". The program checks each character to see if it is a space, if it is the program identifies this a gap between letter, for example: MSG = ".... .." -*the function runs*- EncodedLetter = "....". Then that value is back searched through a dictionary(using lists) to find what EncodedLetter's key whould be, in this case it's "H", the program also checks for double spaces which represent the space between two words. At this point in time it may sound fully functional; however after finding one encoded letter it can't find another, so earlier ".... .." it can't find ".." even though I reset the variable after it successfully decodes a letter.
