This heroically irritating article on portable sound recording is a great introduction, assuming you're comfortable with author Gina Fant-Saez's six commandments: 1) You need to spend $5000 to get started. 2) Macs are for creative people. Only an accountant would buy a PC. 3) Pro Tools is great, only losers use other sequencers. 4) 'Most musicians' don't want to tweak soft synths through a MIDI controller. 5) M-Audio are brilliant, because they run Pro Tools. 6) If you buy a PC, 'I guarantee you will have headache upon headache trying to get everything working.' Hmm... Alternatively: Build a studio for £27 or £500. (via Make)
