Engine14's studio is centered around a iMac running a 3.60 GHz Intel Core i5 processor, with 8 GB of 1333 MHz of DDR3 SDRAM.  Analog to digital conversion occurs through a Focusrite Liquid Saffire 56 firewire interface, and monitoring is done through KRK Rokit 8 speakers.  We use Garageband as our Digital Audio Workstation software.
