Query: Great for recording music and archiving older media formats

I have found this device to work perfectly and create sound files of very good quality. It's not quite CD-quality, but it is great nonetheless. I use the audio interface to connect my 4-track recorder to my computer. I can record to my computer (via third-party software, but you can use whatever recording software your computer comes with) with my guitar, keyboard, microphone, and so on and entirely bypass my 4-track's tape recorder. I am not sure if the whole route from guitar to computer is completely digital, but I do know that the resulting sound is much better than any analog tape could ever make. This is also the cheapest way to record analog technologies (cassette, vinyl) to a digital sound file on your computer. From there, you can make your own CDs and MP3s. You'll be very happy with this device.
