Re: What computers work best for recording?
Roughly 80% of getting a computer to work well as a DAW comes down to setup and tweaks. Bios, memory (virtual) configurations, hardware settings... that sort of thing.
This stuff is all handled behind the scened by the OS nowadays, for the most part. I don't think I've touched a BIOS in 5 years.
I've been running DAW's for many years, dozens of tracks, piles of plug-ins, and IME the only things you really need to do, other than have a good machine, are:
- Do all your recording onto a separate drive, i.e. not the one your programs and OS reside on. This is by far the most important tip. A separate partition is not sufficient - it has to be a second physical drive. A second internal drive is best, but a good USB or Firewire external will suffice if you can't put in a drive for some reason. eSATA is by far the best way to hook up an external drive, so if your computer has that, take advantage.
One of the side benefits of recording to an external is portability of your session. You can record on any computer and your session goes with the drive. This is exactly how my band recorded our recent demo.
- If you're using an external drive, your audio interface should be on a different bus. The easiest way to solve this is to use USB for your hard drive and Firewire for your interface. Most of the best interfaces are Firewire, and most external drives are USB only, so Having the interface on Firewire will also prevent things like the keyboard and mouse from bumping into it (though this is a minor concern at best).
- Shut down wireless networking, antivirus, firewall, and as many background apps as you can while you're working in the DAW. When I recorded on a Windows machine, I wrote a couple of bat files to bring everything down and back up again with one click.
That's it. I have a song that has 38 tracks, 3 buses, compressor and EQ on every track, and a couple of reverb plug-ins; it hasn't cracked 10% on one core of the CPU of the base model iMac I bought last year.
