In wich part of the source is
Gotcha. Well, I've done a fair bit of testing like that, and I've never experienced such a huge delay. I wish I could help more, but I'm at a loss without a lot more informat

Gotcha. Well, I've done a fair bit of testing like that, and I've never experienced such a huge delay. I wish I could help more, but I'm at a loss without a lot more information.
Maybe delay could be because of my computer. Later will try new one

I don’t know in which part of pre-compiled source talks about process of getting MI. I would like to check this code structure to understand better how it works.

I use the "-Z" switch and view the output log. It should show pretty much everything. Something like this:

I don't do windows, but I think that once you download, unzip and follow the "README Windows.txt" you should be good to go.
Thank you!!! In which system should I install it for its optimal operation? Linux? Ubuntu? If so, could you inform me to do it and that you have to download and run to achieve the correct installation

I appreciate the help and your answers, and excuse me if they are repetitive questions but I'm really very lost...

Linux is the native environment. If you want to use Linux, download and run dsd-fme/download-and-install.sh at audio_work · lwvmobile/dsd-fme
If you want to run windows, follow the steps in the previous message. There is no installer for windows that I saw. Just unzip and follow the instructions in the readme file.

It dawned on me after I replied that you probably meant the source code. Without knowing specifically what you are trying to accomplish, it's hard to answer.

I greatly appreciate your patience.
I'm still very lost... I currently have the normal DSD version of Louis Erig Herve and CYGWIN installed. I'm on Windows10 64bits... I already downloaded the DSD-FME version from the link they gave me for Windows. As start? How do I call the new version of DSD-FME and not the previous one I had? INSTALL THIS VERSION SO I CAN LISTEN TO NXDN WITH THE KNOWN ENCRYPTION KEY I HAVE. Excuse me for being so ignorant on this topic but I have been looking for information for 2 days to be able to install and get the new version up and running. I have read the README file but I really don't understand how to run that version. I already have itpp and cygwin and mbelib installed... My normal DSD already works, I just want to implement the function of being able to enter the encryption key to be able to listen,

UPDATE: I already managed to run the dsd-fme... what I can't do is how to place the NXDN encryption key that I have... where do I place it and what command should I place? It's worth mentioning that I couldn't get it to run from Cygwin... It only runs when clicking on 1aa - start-dsd-fme.bat Tips? Where do I place the key and what should I modify?

If you are using NCurses, you can hit the "up" arrow key then follow the prompts for key entry. If you want to permanently add the key, edit the "nxdn_sc_key.csv" located in dsd-fme/examples and edit the startup batch file, like; dsd-fme -k examples/nxdn_sc_key.csv. Using "dsd-fme -h" should show the help text. Once again, I'm not familiar with the windows version, so some things may be a little different.

Ok thanks, and do you know in which part of the source Pre-compiled c-code is the part about “algorithm: RC4 + IVs” receiving? I would like to check it to understand better how it works.

Hello, I already have DSD-FME working correctly in Cygwin. A doubt now what command should I use? I want to listen to NXDN48 With the encryption key 16871, my input and output devices are the defaults 1, 1, I'm struggling with the commands I don't know which ones I should use

Except for protocol specific code, probably what you are looking for is in dsd-mbe.c.

The command line switch for NXDN48 is "-f1" and to manually enter a scrambler key, the switch is "-R". So, a simple command should be like:
Code:
dsd-fme -fi -R 16871 -N 2> log.ans
I'm guessing the audio inputs and outputs should probably be handled by sound mapper or whatever it is that windows uses.
