Is there an app with which you can record music via line cables?

I'm looking for an app that can be used to record music via the line cable. I used to have an MP3 player with which you could record the music if you plugged the line cable into the player and into the headphone jack of any device (laptop, radio, television, etc.).

I thought to myself that it could also be an app.

If this app actually exists: What is its name?

What to record at all?

That would not depend on an app but on whether the device has an appropriate input at all.

I mean, of course, the smartphone (where else are there apps?), Since there are headphones with micro, the input should already be available.

For example on tablets, smart TVs, game consoles, and then the question of whether Android or iOS.

You would first need an adapter that separates the input and output. Then the signal would only be mono, since a connected microphone would also be mono. Then all you had to do was look for an app with something like "Record" or "Record".

Really? I know it from the other devices under the German name "Applications" / "Programs".
But back to the topic: I have a Samsung Galaxy J3

Or would that also work with the laptop?
