You can easily point to graphical quality if you want to demonstrate how gaming gets better and better. Look at a screenshot of Pong and then peer over at one of Gran Turismo - you likely won't hear any arguments about which one looks better. In the face of pretty textures and 1080p resolutions, discussions about sound quality tends to fall by the wayside when a game puts jaw-dropping visuals up on the screen. However, what you hear is just as important as what you see.

Moving from the Atari 2600 to the Nintendo Entertainment System alone brought us out of the bleeping and blooping age and into games filled with music and a variety of sound. The Atari 2600 came with support for a whopping two voices, but the NES upped the ante with five channels, each supporting a set frequency spectrum to create something akin to a fancy tone generator. The Sony PlayStation arrived a few generations later to give us high quality CD audio music and actual voices in games. The Xbox treated us to Dolby Digital surround sound rendered in-game. On the fly surround-sound encoding brought gaming one step closer to replicating the hallowed movie standard.

However, when it comes to game audio, technical quality can easily lag behind intrinsic quality. You don't always need the best hardware to carry a catchy tune. The soundtrack to Super Mario Bros easily proves we don't need reference-quality music or fully orchestral scores for all games. The technical merits of the score would rank quite low, but for sheer fun and appropriateness, the soundtrack stands out and is one that gamers still remember quite fondly. Cartoon-like games might get away with a technically simple score, but as graphics get more complex and lifelike, the sounds within those games have to keep up too. God of War's grandiose soundtrack wouldn't have sounded nearly as good if the developers only had the audio range of the NES to work with. We checked in with Konami's sound director for the highly anticipated PS3 game Metal Gear Solid 4 for more details on what we can expect from next-gen audio.

PlayStation 3 Audio
Next-gen consoles like the PlayStation 3 make considerable inroads into improving what goes into your ears. The PS3 will be able to run up to 512 different voices, and apply different sound layers onto them depending on what the developer wishes. More voices means more concurrent sounds--like background music, cars screeching, crashing, guns shooting, and people talking. More layers means more ways to filter the sound. For example, the developer can change the sound of a gunshot to fit into a cave-like environment. The PS3 will support up to eight channels of audio, or 7.1, running at 96KBs per channel. Reduced-channel formats, like Dolby Digital 5.1, will have higher bit-rate audio streams. We've had 5.1 surround sound since the last generation of games, but expect more games to take advantage of the virtualization features with better sound placement.

               PlayStation  PlayStation 2 PlayStation 3
Audio Processor    SPU    SPU2+CPU       Cell SPE
Number of Voices    24          48             512
Sampling Frequency 44.1kHz 44.1/48 kHz    44.1/48 kHz
Sound Formats    Stereo Stereo/DTS Stereo/Dolby Digital/DTS
Sound Memory       512KB       2MB    0-256MB(shared system memory)

The Cell processor's Synergistic Processing Elements (SPEs) will take care of the audio-processing needs in the PlayStation 3, but developers will have to be careful about balancing system resources since many other game functions also run through the Cell. According to Sotaro Tojima, sound director for Metal Gear Solid 4, "There's no hiding the fact that [the Cell] will have to handle many duties including graphics, AI, and sound." Developers will have to make compromises. There is, after all, a finite amount of processing power. With respect to Metal Gear Solid 4, Tojima mentions that "The MGS team is currently surveying the right balance for all of this. A major priority for the team is to delegate a very generous amount of processing power to sound quality."

Each SPE on the Cell processor consists of 21 million transistors, two thirds of which is dedicated to SRAM, leaving seven million transistors for logic. SRAM acts as a small data cache and the logic portion performs all the calculations. In comparison, Creative's new X-Fi sound processor has 51 million transistors, and its previous chip, the Audigy, had 4.6 million transistors.

The PS3 will store audio on shared system memory, so sound files will have to compete for space with other files relating to running the game. Tojima's team "has a knack for 'cheating' or figuring out clever ways to squeeze out a lot of sound quality." The team managed to make an excellent-sounding backdrop for Metal Gear Solid 3 on the PlayStation 2, despite being limited to a relatively small amount of processing power and sound memory.

Tojima explains that limited storage space can degrade sound quality because developers are forced to use poor sound effects to save space. Tojima points out that, "Until now, the sound for in-game cinematics has been quite good. However, sound quality tends to take a hit when the player takes over and begins to play the game." We've seen this time and again on the PlayStation 2. Cinematic cutscenes playback with full surround sound and increased bit rates, but once the action starts, the music and sound all play second fiddle to a real-time graphics engine, with in-game audio generally dropping down to two-channel stereo.

S*** Goes Surround
That's all going to change on the PlayStation 3. "With next-generation consoles, both cinematics and in-game sound will closely resemble those found in Hollywood films," according to Tojima. He fully expects gamers to "be surprised by the quality of sound coming into their ears--the sound will react to their conditions in the 3D world like never before." For example, in the scenario where a bottle falls off a table, hits a metal shovel, and then rolls onto a carpet, conventional sound processing would have the bottle make the same sounds regardless of the environment, or what it collides with. That same scenario on the PlayStation 3 might have the bottle make a metallic tink when it hits the shovel, and then create a muffled rolling sound as it travels across the carpet. If the room had its own sound variables, the bottles sound might get take on some echo if in a bathroom, or get slightly quieter if in a bedroom. Then you have to factor in on-the-fly surround encoding, which would make the bottle pan from front to back or side to side in your room, depending upon the way it rolled.

The Metal Gear Solid team flew around the world to capture specific sounds for environments in the game. The group actually lugged surround-sound audio-recording equipment to capture sounds from undisclosed locations all around the world. Tojima's team also recorded special sound effects just for the game, instead of using prerecorded, CD-based sounds.

The new audio-processing capabilities of the PlayStation 3 allow Tojima and his team to manipulate sound in a variety of different ways. Tojima says that, "With this power, we can give the player a better environment to experience, as the hardware can produce more sounds in real time based on where the player is in a room and what objects are in that room." Last year's Tokyo Game Show trailer emphasized the theme "No place to hide!" and Tojima, as sound director, will do all he can to envelop the player in the world of Metal Gear Solid. "In a battlefield with no place to hide, you will hear impending dangers all around you, in all 360 degrees."

You'll need to have surround-sound support to get the most our of next-gen audio. Add a 7.1 or 5.1 surround system right beneath that HDTV on your next-gen preparation shopping list. The difference between stereo and 5.1 sound is readily noticeable to most people as the sounds coming from a subwoofer and rear speakers are hard to miss. A jump from 5.1 to 7.1 is a bit more subtle since you're basically only adding two additional speakers to an existing surround setup. Home theater in a box setups (HTIBs) start as low as $200. Consider picking up a set if you plan on getting a PlayStation 3 and Metal Gear Solid 4.

拥有高级音响的玩家有福了，MGS4将会运用7.1声道呢~.

对你的签名到是相当不爽!

PS3-7.1声道的话很多人还是享用不起的
现在2极管价格不匪.玩到5.1已经相当不错了!

作者: 贪婪水鬼 时间: 2006-4-22 04:04
Gamespot的文阿........

7.1的确是有点远，720P+5.1就足够好了...........

作者: scast 时间: 2006-4-22 05:09
Dolby Digital ps2也支持啊？

作者: sorrowrain2 时间: 2006-4-22 06:15
一旦对音响有了兴趣, 那钱烧都烧不玩....

作者: 小庄 时间: 2006-4-22 08:07
又多了一个配件,看来又得抓紧挣钱。

作者: ly781223 时间: 2006-4-22 08:59
7.1我家不够大，没那么多地方放音箱

作者: fatyme 时间: 2006-4-22 09:04
看来像体验一把
5.1算是入门了
7.1不知道明年能不能降下来
能降的话直接上7.1也好
现在要开始攒钱了
应该赶得上

作者: mark603 时间: 2006-4-22 09:52
在國內大部分玩家夠錢買PS3就已經很不錯。。。
這些玩意在國外都不是每個人玩得起跟想玩。。。游戲不用玩得這么辛苦吧？

作者: 象拔蚌 时间: 2006-4-22 10:10
多个功能有啥不好？对有米的玩家这是福音，没米的不用这功能就是了！

作者: ft24219 时间: 2006-4-22 10:14
还是比较关注游戏,则么老是放这种无关痛痒的新闻

作者: banprestia 时间: 2006-4-22 10:37
翻译一下啊！！！意味着又要买高端音响了。。。。。。

对MGS 只对井上喜久子JJ的配音感兴趣........

作者: lws8891 时间: 2006-4-22 11:08
没钱买得起啊，支持下好了

作者: rishiyo 时间: 2006-4-22 11:13
7.1到时候怎么接啊,各位有没有知道的?
是只能用光纤输出到功放吗?ps3内置杜比和DTS解码那再买支持解码的功放岂不是浪费??= =
要享受多声道的话到底要怎么办?

将来玩游戏的时候可以用小的迷你音响吧……
大的又贵又占地方，当然效果一流了！

5.1是左前，中置（主要是人声，对白），右前，左后，右后，那个.1就是低音炮拉，不过小空间放低音很不爽
7.1加的是在左前和左后之间呢还是一个顶上，一个脑后？

最近两天这个楼主一改往日吐酸水的风格发起文章来了。大概是因为索尼迟迟拿不出东西来吧？索犯的逆袭？

不过，在发帖之前还是建议楼主读读版规：禁止发纯外文新闻。

印象里：5.1是四个角+前+低音炮然后7.1背后添两个环绕声

这种配置太烂了……
后面用到的地方本来就少，怎么还一下浪费两个？

还是慢慢看到底买什么吧！

作者: 贪婪水鬼 时间: 2006-4-22 17:24
7.1太奢侈，不考虑，5.1美..............玩游戏，5.1已经可以使你身临其境了，PS3非要做1080P+7.1是吃饱了撑的

作者: ceefw 时间: 2006-4-22 17:37
我说房间没有30坪以上的人就别整啥7.1了

作者: xukai 时间: 2006-4-22 17:47
7.1~~对大多数人也许都不实际吧~~

作者: 高人啊! 时间: 2006-4-22 17:51
1080P 13.1就满足了~

我的老P4主板上集成的声卡都可以7.1，
不过音响设备贵，只想看看MGS4的可操作试玩，看了N多视频实在无趣，根本不知真假，只等试玩。

顶一下下.......................

作者: (忍) 时间: 2006-4-23 16:43
我倒现在才开始想玩5.1现在既然杀出7.1
不过PS2支持5.1的游戏还不算N多..
估计PS3支持7.1的也只是少数..
少玩音响的人现在7.1要多少钱(一般的)

作者: sk4 时间: 2006-4-23 16:55
PS3的花费再度提高................

作者: sakuraryota 时间: 2006-4-23 16:59
音响要买的话10W算入门
不想和这样的东西扯上关系，喜欢上了真的就不能自拔了啊

作者: blue 时间: 2006-4-23 19:07
为了这个游戏，正版是必需的~~

作者: 重考生 时间: 2006-4-23 23:00
体会更多的，享受更好的，P. S. 3

作者: 琳斯雷特渥克 时间: 2006-4-24 05:46
暂时来说7.1对於我很遥远

作者: saint0708 时间: 2006-4-24 16:23
7.1声道解码器功放恐怕价格比PS3还贵吧。。。
因为PS3不会给你提供7.1声道模拟输出的。一定是数字输出。需要子后持DTS:ES或者DOLBY DIGITAL的新解码格式才行。目前这类功放价格还太夸张。倒是完整支持5.1数字AC3输出就不错了。7.1比5.1不会有太大区别的。至少不会象从2.0到5.1的差别那么大。5.1的数字解码器现在不过是1000到2000的入门样子。大部分买得起PS3的玩家应该能接受的。而象罗技Z-5500之类3000元以内的整合系统都是内置5.1解码器和功放的。

从ATARI2600到现在确实是一个不小的进步，但也确实，并不是好的硬件一定能带来好的音乐，MARIO的音乐确实经典，FF8的旋律至今仍在脑边回荡，PS3的音质我想国内的玩家恐怕很少有人有福享受吧，至今停留在CREATIVE 5.1的环绕声体验中，7.1对偶来说简直是难以体验的享受

作者: qlwuu 时间: 2006-4-26 10:57
这种功能根本就是浮云，对绝绝大多数玩家都没什么意义。

作者: lionking 时间: 2006-4-26 12:42
买不起7.1的音箱。。。

作者: fisher119 时间: 2006-4-26 17:39
7.1……箱子好多啊……

作者: nbvcxz 时间: 2006-4-26 19:00
没多大意思，家里连5.1都没有
