If you just want to make a simple backup, you can create an image file of your CDs and upload them to somewhere like the Internet Archive to preserve their content. There are various software capable of creating image files, including InfraRecorder and WinCDEmu. Here's a simple guide on how to create an ISO image file from a CD or DVD. Source: 12 months ago

Despite what the page says, the file in question is actually a .img file, which won't be accepted by most programs out of the box. To convert it into a more usable .iso format, I would recommend using WinCDEmu for Windows, but other CD-related tools should be able to do the job as well. I don't know of any solutions for MacOS or Linux; comments for those platforms would be appreciated! Source: about 1 year ago

What? oh. I used this version from the wayback machine, and then opened the iso with THIS handy dandy and quite small tool! I do that with a lot of games actually,. Source: about 1 year ago

Use WinCDEmu to mount the ISO, not the built-in Windows "Mount" command. Source: about 1 year ago

I downloaded Preinstalled ZIP folder (2.26GB) and used WinCDEmu (an open-source CD/DVD/BD emulator) to mount the file. This is because the games were originally released on CDs or DVDs. ISOs and ROMs are basically electronic versions of the original game discs. OGD has a guide on all of this. Source: about 1 year ago

Just take that lossless track and encode it to 320kbps Vorbis using a good quality encoder (Foobar or freac). Then load both the files into any ABX comparison tool. It will load both samples then shuffle them so X/Y are random and you have to tell it which you think is A and which you think is B. Source: about 1 year ago

Evidently this will work (though sadly no Linux version): https://freac.org/. Source: over 2 years ago
