"It all started with the four-track cassette recorder, really. That gave budding bedroom musicians the chance to make their own music (it was also the start of the lo-fi movement, as if people had forgotten that much of the great music of the ‘60s was made on four-track machines, with very good sound, but that's another story).
That was just the first herald of the recording revolution, however. These days, anyone with a halfway decent computer can record, mix, and put their own music on CD. And, thanks to technology, you don't even need to play an instrument to do it.
Obviously, the better your computer, the faster the speed and CPU capacity, which you'll need to make music. Have Windows 98 or higher. A hard drive of at least 15GB is good, and at least 128 MB RAM. Most importantly, make sure you have a good soundcard, otherwise whatever software you use either won't operate, or won't work properly and to its full potential."
