Nowadays, nearly every computer on the market is good enough to use for basic sound recording, editing and mixing. Your main aim is to get started with something, and learn your craft. But if you’re simply getting started and doing your own music production in your own time, then a reasonable spec budget PC is probably the way to go.

Instant loading of programs, files, and seamless production, with the ability to render high quality audio without taxing your system.

Most modern computers can surprisingly handle the workload for recording, even many of the most basic consumer PCs. Remember, we are talking about audio processing here. In the area of computers, though, you can be a little bit more flexible than with your other studio gear. Most of us have to make a little budget go a long way.
