What Happened To PC Gaming Audio?
Thanks to The Adrenaline Vault for its feature discussing why computer audio has become a critically undervalued part of a PC purchase. The author indicates the worry that "computer audio is taken for granted, and that other components make the difference between high- and low-end systems", and voices concern that "most new [PC] computer games - including major releases - don't take advantage in any significant way of the capabilities of the latest generation of audio cards." He ends with the heartfelt wish: "I'm waiting for the day when I hear someone say, 'That game sounds so great, I have to buy it!' I hope people become more educated about audio so they can talk about it with the same enthusiasm that they discuss 3D video hardware acceleration or high definition plasma screens."
I think one reason that we don't see Games taking advantage of the latest gee-whiz auto card features is that PC audio cards have been able to deliver realism for a long time now. Sounds are sampled, environmental processing effects applied (which are, in the main, not processor intensive enough to require much hardware acceleration) and, with a decent pair of stereo speakers - to say nothing of a 5.1 system, the effect is realistic enough that you feel immersed in the game. The same is only just becoming true of 3D graphics with the current state-of-the-art hardware, and there's still a long way to go.
As many people point out, for the unwashed masses who cannot tell the difference between a 128kbps MP3 and the original audio, pro-level audio soundcards like the Audigy are just overkill and will remain in the domain of the musician and those who care about sound quality. We are a lot more forgiving about audio quality than visual quality; I know I will happily listen to a LW radio broadcast, but I find a low signal TV broadcast unwatchable.
Until games use more audio gimmicks; real-time physically modelled sounds generated on the fly for example, we will have no requirements over those currently implemented on all on-board audio.
You want to hear people rave about sound, then it will have to be sold to them. In movies this already happens in the cinema, which makes people want their own home-entertainment system. Since there's no similar event for gaming (appart from cult-gatherings, etc), how many people will consider it an issue? At the same time, the integration of game-consoles into existing entertainment systems has raised the attention-level a bit.
There's also the matter of soundtracks, which is an underused option in games. A great soundtrack will make me want to see a movie and vice versa.
All that being said, I have not really found sound in games lacking, even though I have $7 pc-speakers. I find wearing earphones actually gives me an advantage in games like counterstrike, in which hearing the enemy approach is of vital importance.
