Apple’s OS X software is optimized for recording and editing digital media. There are many pieces of recording software designed for use with Apple’s operating system, including Garageband, Logic Pro and Pro Tools. The iMac computer allows you to record sound through either the built-in microphone or the line-in port (located on the back of the computer), but you will need a pre-amp or powered microphone to use a microphone with the line-in port. Using a professional microphone will yield a much cleaner audio signal with less background interference than the built-in microphone. You can also connect some microphones or other sound sources to the computer through a USB or Firewire port. Writer Bio
