 Understand the key audio limitations of game platforms Learning Objectives

“The term ‘platform’ refers to the specific combination of electronic components or computer hardware which, in conjunction with software, allows a video game to operate.” Game Platforms Video game platforms fall under several broad categories, as follows.  PC – Windows, Mac, Linux  Home Console – Xbox One, PS4, Wii U  Handheld Console – PS Vita, 3DS  Mobile – Android, iOS, Blackberry

Audio quality (among other things) can be limited by the amount of storage available for the game.  Xbox 360 games are stored on DVDs – these have a memory capacity of 4.7GB which must store the entire game.  PS3 games are stored on Blu-Ray discs, which have a memory capacity of 25 or 50GB, allowing for much higher quality assets to be stored.  PC games are usually installed directly to a hard drive, which commonly range up to 2TB. Limitations Storage

Audio quality is seriously limited by the output device.  Fallout 3 is a game capable of outputting 7.1 surround sound, but this will obviously only be available for 7.1 setups.  5.1 setups (or even stereo) will have drastically reduced audio quality, through no fault of the game’s developers. Limitations Output

Limitations

An SPU is the device responsible for converting a digital audio file to an analogue signal.  Some SPUs are integrated (consoles, phones etc)  PCs have a range of SPUs available to them  Low end SPUs are capable of stereo output and usually some form of input  Higher end SPUs are often capable of 5.1 or even 7.1 surround sound, along with input. Limitations Sound Processing Unit (SPU)

These include, but are not limited to:  Storage capacity  Sound output device and available hardware  SPU / sound card  RAM  Sample rate Summary Audio quality is limited by a range of issues, based on the game platform.
