There was a time when shooting HD video meant big equipment and even bigger budgets. Nowadays, you can shoot amazing HD footage with something that costs under $200 and fits in your pocket. But how about great sound, or even surround sound, to match that awesome video? Like HD video, surround sound used to be bulky, expensive, and reserved for use by the pros. Nowadays, thanks to a company called Holophone (not to be confused with the instrument from Futurama) just about anyone can add 5.1 surround sound to their home movies or independent films without having a duffel bag full of equipment or a Hollywood budget.
