macos 虚拟环绕声

Moviegoers already know the bliss of a good surround sound setup, but PC gamers have an even better reason to invest in a little audio immersion: beating the snot out of their online opponents. A good surround sound system can make a surprising amount of difference in fast-paced competitive games, helping you hear where other players are on the map.

看电影的人已经知道环绕声设置很好的幸福，但是PC游戏玩家有更好的理由投资一点音频沉浸感：击败在线对手。 良好的环绕声系统可以在快节奏的竞技游戏中产生惊人的变化，从而帮助您了解其他玩家在地图上的位置。

When shopping for a gaming headset, you may see “surround” sound advertised, but it isn’t always as good as it claims to be—there’s a difference between “true” surround sound and “virtual” surround sound. Let’s start by talking about how stereo headphones work, and how different types of surround sound improve on them.

购买游戏耳机时，您可能会看到“环绕声”的广告，但并不总是如其声称的那样好-“真实”环绕声和“虚拟”环绕声之间存在差异。 让我们从谈论立体声耳机的工作原理以及如何改善不同类型的环绕声开始。

立体声耳机：基本知识 (Stereo Headphones: Just the Basics)

These are you basic, no-nonsense headphones—the kind you can buy at any electronics or department store, or the earbuds that came with your phone. You probably have a couple of pairs lying around the house already. They’ll get the job done in terms of pure sound, and many include a built-in microphone for communication. But with only two driver units (aka speakers—one in each ear), they’re limited in terms of surround sound performance—all you have to work with are the left and right audio channels.

这些是您基本的，毫不费力的耳机-您可以在任何电子产品或百货商店或手机随附的耳塞中购买的耳机。 您可能已经在屋子周围摆了几对。 他们将以纯净的声音完成工作，其中许多都包含用于通信的内置麦克风。 但是只有两个驱动器单元(又名扬声器，每个耳朵一个)，它们在环绕声性能方面受到限制，您需要使用的只是左右声道。

More advanced stereo headphones can reproduce an excellent range of sound frequencies. In fact, it’s much easier to get quality sound from headphones than from speakers, since the drivers in headphones are relatively tiny and the environment for the audio itself (your own ears and auditory canals) is more or less controlled. But for surround effects that enhance a gaming experience, you’ll probably want something extra.

更高级的立体声耳机可以再现出色的声音频率范围。 实际上，从耳机中获得高质量的声音比从扬声器中获得高质量的声音要容易得多，因为耳机中的驱动器相对较小，并且音频本身(您自己的耳朵和听觉通道)的环境或多或少受到控制。 但是对于增强游戏体验的环绕声效果，您可能需要一些额外的东西。

(Note: If you’re looking to buy stereo headphones for gaming, we recommend skipping “gaming” headsets—you’ll get better audio quality for the price with a good pair of music headphones, and you can always add a ModMic to them if you need a microphone.)

(请注意：(如果您想购买用于游戏的立体声耳机，我们建议您跳过“游戏”耳机。通过使用一副好的音乐耳机，您可以以较低的价格获得更好的音频质量，并且随时可以向其添加ModMic如果您需要麦克风。)

虚拟环绕声：经济实惠的沉浸式游戏 (Virtual Surround Sound: More Immersive Gaming on a Budget)

Audio software engineers have been hard at work on ways to simulate a surround sound setup on more limited hardware. There are many different competing methods for this, but all of them basically boil down to “fooling” your brain into hearing a directional component that’s more complex than a simple 2-channel setup would be able to deliver in stereo.

音频软件工程师一直在努力在更有限的硬件上模拟环绕声设置的方法。 有许多不同的竞争方法，但是基本上所有这些方法都归结为“欺骗”您的大脑以听取定向成分，该成分比简单的2声道设置所能传递的立体声更为复杂。

Imagine someone directly to your left is speaking to you. You’ll hear the sound of their voice in your left ear, of course, but you’ll also hear it in your right—just with a lower volume and an almost imperceptible delay. Turn your head to face the person who’s speaking, and both your ears should hear the words at approximately the same time and the same volume. Even normal stereo audio mixing for music and television takes account of this; a singer or instrument is almost never heard completely in one ear or the other.

想象一下，有人直接在您的左边在对您讲话。 当然，您会在左耳听到他们声音的声音，但是在您的右耳也会听到声音–只是音量较低且几乎看不到延迟。 转过头面对说话的人，两只耳朵都应该在大约相同的时间和相同的音量下听到这些单词。 即使是音乐和电视的普通立体声混音，也要考虑到这一点。 歌手或乐器几乎从来没有完全听完一只耳朵或另一只耳朵的声音。

Normal stereo headphones will use volume to help you determine where a sound is coming from, but virtual surround sound takes it even further. It also delays the sound by a tiny fraction in the “off” ear, among several other processing tricks, to fool your brain into thinking it’s hearing sound from much more than two directions at once. This delay may even be exaggerated to help pinpoint the direction.

普通的立体声耳机会使用音量来帮助您确定声音的来源，而虚拟环绕声则使声音更远。 除其他几种处理技巧外，它还使“离耳”的声音延迟了一小部分，从而使您的大脑误以为它一次从两个以上的方向听到声音。 甚至会夸大此延迟，以帮助查明方向。

Many of these other tricks are proprietary, and differ between the many virtual surround standards—such as Dolby Headphone, Creative Media Surround Sound 3D (CMSS-3D Headphone), and DTS Headphone X—so we couldn’t explain it all even if we wanted to—but we’ve used virtual headphones before, and the difference is definitely noticeable.

这些其他许多技巧都是专有的，并且在许多虚拟环绕标准(例如杜比耳机，Creative Media Surround Sound 3D(CMSS-3D耳机)和DTS耳机X)之间有所不同，因此即使我们想要的，但是我们之前使用过虚拟耳机，而且两者之间的区别肯定很明显。

Note that the vast majority of gaming headsets—even those marketed as “5.1” or “7.1” surround sound—are using standard stereo drivers with Dolby or DTS surround sound virtualization. Check the specifications on the packaging: if it only lists one or two sizes of drivers, it’s a stereo set using virtual surround sound. Some gamers prefer a quality stereo setup with virtual surround to “true” surround sound, since the single dedicated driver in each ear is often of higher quality than the multiple drivers in more complex setups…and they’re smaller and much less expensive.

请注意，绝大多数游戏耳机-甚至以“ 5.1”或“ 7.1”环绕声销售的那些-都使用具有Dolby或DTS环绕声虚拟化功能的标准立体声驱动程序。 检查包装上的规格：如果仅列出一种或两种尺寸的驱动器，则它是使用虚拟环绕声的立体声音响。 有些游戏玩家更喜欢具有虚拟环绕声的高质量立体声设置，而不是“真实”的环绕声，因为在更复杂的设置中，每只耳朵的单个专用驱动器通常比多个驱动器具有更高的质量……而且它们更小，更便宜。

Some popular virtual surround headsets include the SteelSeries Siberia 350 ($95) and the Logitech G430 ($40).

一些流行的虚拟环绕声耳机包括SteelSeries Siberia 350 (95美元)和Logitech G430 (40美元)。

真正的5.1环绕声：真正的McCoy (True 5.1 Surround Sound: The Real McCoy)

As the name implies, 5.1 surround sound headphones use five distinct drivers split across both ears, plus an extra sixth driver for low-frequency bass. These are physically positioned around your ear to help simulate sounds coming from a variety of directions: a center channel, a front-left channel, a front-right channel, a rear-left channel, and a rear-right channel, plus a “subwoofer” for bass.

顾名思义，5.1环绕声耳机使用在两个耳朵上分开的五个不同的驱动器，以及一个用于低频低音的额外第六个驱动器。 它们物理定位在您的耳朵周围，以帮助模拟来自各种方向的声音：中央声道，左前声道，右前声道，左后声道和右后声道，以及“低音炮”。

Vibrating the drivers in this setup at different volumes, corresponding to the sound sources in a movie or game, creates an impressive surround sound effect. For example, an enemy sneaking up directly behind the player will create footstep noises of equal volume in both the rear-left and rear-right channels, while the same enemy approaching from slightly to the left will be louder in the rear-left channel than the right. Aside from pure entertainment value, this can be incredibly handy in online multiplayer games, allowing players to instantly react to threats from multiple directions without having to see them all on screen.

在此设置中，驱动程序以与电影或游戏中的声源相对应的不同音量振动，从而产生令人印象深刻的环绕声效果。 例如，一个敌人在玩家的正后方潜行，将在左后方和右后方通道中产生相同音量的脚步声，而从左向后稍微靠近的同一个敌人在左后方通道中的声音将大于正确的。 除了纯粹的娱乐价值外，这在在线多人游戏中非常方便，使玩家可以立即应对来自多个方向的威胁，而不必在屏幕上看到它们。

Most modern games from large developers and publishers will work with surround sound in at least 5.1 channels. The precise handling of the sound is shared between the game and your computer’s sound card (or, if you use a USB headset, the headset software installed on your operating system). This isn’t just for games, either—if you’re watching a movie on your computer, either from a DVD or from an online video service like Netflix, you can get full 5.1 support—as long as your video player or streaming service offers it.

来自大型开发商和发行商的大多数现代游戏都可以在至少5.1声道中使用环绕声。 游戏和计算机的声卡(或者，如果使用USB耳机，则是操作系统上安装的耳机软件)之间共享声音的精确处理方式。 这不仅适用于游戏，如果您正在计算机上观看DVD，DVD或Netflix等在线视频服务中的电影，则只要获得视频播放器或流媒体服务，您就可以获得完整的5.1支持提供它。

“True” 5.1 surround sound headsets (as opposed to stereo virtual surround) include the Cooler Master Sirus and the Roccat Kave XTD ($160).

“ True” 5.1环绕声耳机(与立体声虚拟环绕声相反)包括Cooler Master Sirus和Roccat Kave XTD (160美元)。

真正的7.1环绕声：音频过大 (True 7.1 Surround Sound: Audio Overkill)

7.1-channel headphones operate on the same principles as 5.1 headphones, just with more drivers. In addition to the dedicated drivers for center, front-left/right, rear left/right, rear-right, and bass in each ear, 7.1 headphones include extra left-surround and right-surround channels for sounds coming from directly left and right in a game or movie.

7.1通道耳机的工作原理与5.1耳机相同，只是驱动程序更多。 除了用于每个耳朵的中置，左前/右后，左后/右后，右后和低音的专用驱动程序外，7.1耳机还包括额外的左环绕声和右环绕声通道，以使声音直接来自左右声道在游戏或电影中。

The difference between 5.1 and 7.1 is much more negligible than the step up between stereo or virtual surround to true 5.1. Technically it’s more immersive, but since 7.1-channel headsets are more expensive, you may be looking at diminishing returns for the fancier hardware. Also, keep in mind that some games only support 5.1 surround sound, in which case those 7.1 headphones won’t matter.

5.1和7.1之间的差异远比立体声或虚拟环绕声升至真正5.1时的差异要小得多。 从技术上讲，它更具身临其境的感觉，但是由于7.1声道耳机的价格更高，因此您可能会希望购买更高级的硬件而获得的回报减少。 另外，请记住，某些游戏仅支持5.1环绕声，在这种情况下，那些7.1耳机将无关紧要。

“True” 7.1 surround sound headsets include the ASUS STRIX ($190) and the Razer Tiamat (Discontinued, but still available in some stores).

“ True” 7.1环绕声耳机包括ASUS STRIX (190美元)和Razer Tiamat(已停产，但在某些商店仍然有售)。

其他注意事项：USB和无线 (Other Considerations: USB and Wireless)

As you shop, there are two more things you may want to consider.

购物时，您可能还要考虑两件事。

Some headphones will use USB to connect to your PC, while others will use some sort of multi-plug headphone jack system. It’s usually wiser to go with more modern USB audio. Most laptops and some newer or cheaper desktops don’t have the necessary audio outputs for surround sound on their motherboard, and very few come with a dedicated sound card anymore. A USB surround sound headset handles all of its audio processing through desktop software or an in-line amplifier, which is much easier to manage.

一些耳机将使用USB连接到您的PC，而另一些耳机将使用某种多插头耳机插Kong系统。 使用更现代的USB音频通常更明智。 大多数笔记本电脑以及一些更新或更便宜的台式机在主板上都没有用于环绕声的必要音频输出，并且很少有专用的声卡了。 USB环绕声耳机通过台式机软件或嵌入式放大器处理所有音频处理，这更易于管理。

Also, many newer headsets come equipped with wireless surround sound. It’s a neat feature, especially if you’re used to walking around and doing other things while watching a movie. But since most PC gaming is done directly in front of your computer (well within reach of a USB cord), this is a feature that’s generally not worth the extra expense. Wireless headsets also need to be recharged, and can sometimes experience interference from other wireless gadgets—which isn’t a problem with a dedicated USB or audio cable.

此外，许多较新的耳机都配备了无线环绕声。 这是一项整洁的功能，尤其是如果您习惯在看电影时四处走动和做其他事情时。 但是，由于大多数PC游戏都是直接在您的计算机前进行的(很容易在USB电缆的范围内完成)，因此通常不值得为此付出额外费用。 无线耳机也需要充电，有时可能会受到其他无线设备的干扰-专用USB或音频电缆不会有问题。
