Audacity

 Computers and video/music content have developed by constantly balancing their compatibility with copyright issues. There have been the conflict between copy protection for CDs and DVDs and the law's limits on personal use. And recent advances in computer performance have made it possible to record computer screens with reasonable performance. On the other hand, the technology of the guarding side is also evolving. There are many cases where it is very useful in the range of personal use, and we want to use it while keeping in mind the scope of the law.

I tried using Audacity on Ubuntu Remix installed in my Dynabook N40, which is an audio editing software that is very easy to use, and the Windows and Linux versions are almost the same. By combining Audacity with your computer's audio settings, you can record the sound of your computer. In short, all you have to do is connect the sound output of your computer to the sound input of your computer. Of course, if you try to, you could also record audio from today's subscription services, but please be sure to comply with the laws of your country.

In the past, Windows used to allow you to connect "Output and Input" from the sound settings, but this is no longer possible by default, and you need to install an application such as voicemeeter, but I won't go into that here.

In Ubuntu on my dynabook N40, I installed Pavucontrol and was able to record with Audacity by tweaking the "Set as alternative" item in the "Input Devices" tab.

What you have to be careful of, of course, is that all the sounds of the computer are recorded, so if an error sound occurs during recording due to an operational error, that sound will be recorded as well (:-o). Moreover, Ubuntu Japanese Remix can change the warning sound to "dog" or "water" or "glass" (:-) on the settings menu , but I can't find an item to remove it completely at the moment (;-o). It seems that even if I set the setting volume to zero, the input to Audacity is not zeroed out. I'll try not to touch the dynabook N40 while recording for the time being (lol).
