美洲卡车模拟：1.47 - 世界环境音效

大家可能还记得，去年 SCS Software 的一支小团队前往了美国。不过，我们当时的日程不仅有参加展会、研究当地。我们音效团队的成员也随同前往，为美洲卡车模拟游戏世界录制了许多新的环境音效。今天，我们想要向大家分享一下这些音效的开发情况，它们将会在之后的1.47版本更新中到来！

随着我们不断让我们的卡车模拟游戏世界的音效更具沉浸感，我们在此次版本更新做出的一大改变是通过 FMOD 为我们的虚拟环境加入音效扩散技术。那么，这对于玩家们来说意味着什么呢？现在，大家将留意到多种来自不同方向、距离的音效，基于我们目前具有来自特定地方的现有的基础环境循环的 5.1 音效层。例如，大家也许坐在安静的得州平原的休息区里，倾听着蟋蟀的嘘嘘声，而且你们将会听到它们来自不同的距离，有的远，有的近！

这样的变化不仅仅适用于自然，还有城市。从远处高速公路车流的声音，到附近的警笛声，这些音效不仅将在强度、位置上不同，还会根据你们处于停车或低速、高速形式的状态而改变，即会感受到多普勒效应。音效还会因昼夜循环而变化。

这一新的音效系统让玩家们在经过不同环境时听到不同的音效。在首次更新中将包含数百种音效，所以音效的多样性是非常显著的。

我们带来的另一项改动是针对卡车的方向过滤器。在适用时，我们在音效系统中加入了音效引擎均衡，其根据你们当前的相机视角变化。例如，如果你们的视角在卡车后方，则将发现音效随视角改变而变化。当相机视角固定不动，看着你们的卡车从旁边经过，这时的效果最为明显。

我们很高兴在未来加入这些改动。请注意，这只是音效方面的首个特性引入。今年将会是我们团队又一个忙碌的录音时期，我们期待在合适的时候带来更多更新。

在那之前，请保持关注之后在音效方面的更多消息，我们想要听到大家关于这个话题的想法。

American Truck Simulator: 1.47 - World Ambient Sounds

As you might remember, last year, a small team from SCS Software traveled to the USA. However, visiting expos and researching areas were not the only tasks on our agenda. Members from our sound team also traveled along to record a number of new environmental and ambient sounds for the world of American Truck Simulator. Today we wanted to share with you a glimpse into the development of some of those sounds that will be coming in the next 1.47 update! 

As we continue to make sounds more immersive across our truck sim world, one big change we have made for this update is introducing sound scatter technology through FMOD for our virtual environment. So what does this mean for players? It means you'll now notice a variety of SFX coming from different directions and distances, on top of our base 5.1 sound layer, which has an existing basic environmental loop from a specific place. For example, you may be sitting at a rest area in the quiet Texas plains, hearing the chirping of crickets, but you'll hear them at various distances, some further away, some closer! 

This change not only applies to nature but also in the city too. From the sound of distant highway traffic to a nearby police siren, these sounds will not only vary in intensity and location, but also change depending if you are parked or traveling at low or high speed; where you'll experience the doppler effect. Sounds will also vary depending on the day and night cycle. 

This new sound system allows players to always hear different sounds as they travel through the environment. Hundreds of these sound spots will be included in this first update, so the variety of sounds will be quite noticeable.

Another change we are introducing is a direction filter for trucks. Where applicable, we have included sound engine equalization in the sound system, which works according to your current camera view. For example, if you are using a camera behind the truck, you will hear a change in sound according to that view. The effect is most audible when you are able to watch your truck drive past but the camera remains stationary. 

We are excited to bring these changes in the future. Keep in mind, this is just the first implementation when it comes to sounds. This year will be another busy schedule of recording for our team, and we look forward to bringing more updates in due time. 

Until then, keep an ear out for more news in the future about sounds, we love to hear your thoughts on this topic.
