The Audio Listener acts as a microphone-like device. It receives input from any givenAudio Sourcein the scene and plays sounds through the computer speakers. For most applications it makes the most sense to attach the listener to the MainCamera. If an audio listener is within the boundaries of aReverb Zonereverberation is applied to all audible sounds in the scene. (PRO only) Furthermore,Audio Effectscan be applied to the listener and it will be applied to all audible sounds in the scene.

The Audio Listener has no properties. It simply must be added to work. It is always added to the Main Camera by default.

Details 細(xì)節(jié)
The Audio Listener works in conjunction withAudio Sources, allowing you to create the aural experience for your games. When the Audio Listener is attached to a GameObject in your scene, any Sources that are close enough to the Listener will be picked up and output to the computer's speakers. Each scene can only have 1 Audio Listener to work properly.
音頻偵聽器（Audio Listener）配合音頻源(Audio Sources)，讓你可以為你的游戲創(chuàng)建聽覺體驗(yàn)纯衍。當(dāng)音頻監(jiān)聽器貼在場景中的一個(gè)游戲?qū)ο蠖俺荩魏我纛l源，如果足夠接近偵聽器就會(huì)被獲取并輸出到計(jì)算機(jī)的揚(yáng)聲器。每個(gè)場景只能有1個(gè)音頻偵聽器正常工作瓦堵。
If the Sources are 3D (see import settings inAudio Clip), the Listener will emulate position, velocity and orientation of the sound in the 3D world (You can tweak attenuation and 3D/2D behavior in great detail inAudio Source) . 2D will ignore any 3D processing. For example, if your character walks off a street into a night club, the night club's music should probably be 2D, while the individual voices of characters in the club should be mono with their realistic positioning being handled by Unity.
如果音頻源是3D（ 見音頻剪輯（Audio Clip）中的導(dǎo)入設(shè)置（import settings））基协，偵聽器將模擬在3D世界聲音的位置，速度和方向（你可以調(diào)整衰減和3D/2D行為菇用，這在音頻源（ Audio Source）有非常詳細(xì)的介紹）澜驮。 2D將忽略任何3D處理。例如惋鸥，如果你的人物在街道行走杂穷，走進(jìn)夜總會(huì)，夜總會(huì)的音樂也許應(yīng)該是二維的卦绣，而人物在俱樂部內(nèi)獨(dú)立的聲音耐量，應(yīng)該是伴隨著他們真實(shí)定位的單聲道在Unity中處理。
You should attach the Audio Listener to either the Main Camera or to the GameObject that represents the player. Try both to find what suits your game best.

Audio Source 音頻源
The Audio Source plays back anAudio Clipin the scene. If the Audio Clip is a 3D clip, the source is played back at a given position and will attenuate over distance. The audio can be spread out between speakers (stereo to 7.1) (Spread) and morphed between 3D and 2D (PanLevel). This can be controlled over distance with falloff curves. Also, if thelisteneris within 1 or multipleReverb Zones, reverberations is applied to the source. (PRO only) Individual filters can be applied to each audio source for an even richer audio experience. SeeAudio Effectsfor more details.
音頻源(Audio Source)在場景中播放音頻剪輯(Audio Clip)。如果音頻剪輯(Audio Clip)是一個(gè)3D剪輯暮胧，音頻源是在一個(gè)給定的位置汰现，并會(huì)隨距離衰減這樣的方式進(jìn)行播放。音頻可以在揚(yáng)聲器之間傳播（立體聲至7.1）（擴(kuò)散Spread）和可以在3D和2D（平衡調(diào)整級別PanLevel）之間進(jìn)行轉(zhuǎn)換叔壤。這是可以控制的隨距離衰減曲線。此外口叙，如果偵聽器是在1個(gè)或多個(gè)混響區(qū)中炼绘，回響將會(huì)應(yīng)用到音頻源。 （只專業(yè)版可用）單獨(dú)的過濾器可以應(yīng)用到每個(gè)音頻源妄田，可以得到更豐富的音頻體驗(yàn)俺亮。更多細(xì)節(jié)請參閱音頻效果（Audio Effects）。

Gapless looping
無縫循環(huán)

Importing Audio Assets 導(dǎo)入音頻資源
Unity supports bothCompressedandNativeAudio. Any type of file (except MP3/Ogg Vorbis) will be initially imported asNative. Compressed audio files must be decompressed by the CPU while the game is running, but are smaller in file size. IfStreamis checked the audio is decompressedon the fly, or else the audio is decompressed entirely upon load. Native PCM formats (WAV, AIFF) have the benefit of being higher fidelity without increasing CPU taxation, but create much larger files. Module files (.mod,.it,.s3m..xm) can deliver very high quality with an extremely low footprint.
Unity支持壓縮的和原生的音頻厢破。任何類型的文件（MP3/Ogg Vorbis的除外），最初都以原生音頻導(dǎo)入（Native即不經(jīng)任何處理的音頻本身）治拿。游戲運(yùn)行時(shí)摩泪，壓縮音頻文件必須由CPU解壓縮，但文件要較小劫谅。流(Stream )被選擇见坑，音頻在將運(yùn)行時(shí)解壓縮，或者音頻在加載時(shí)完全解縮捏检。原生PCM格式（WAV荞驴，AIFF）有在不增加CPU資源同時(shí)有更高的保真度的好處，但創(chuàng)建更大的文件贯城。模塊文件（.MOD熊楼，.S3M，. XM）可以提供非常高的質(zhì)量與極低的占用空間冤狡。
As a general rule of thumb,Compressedaudio(or modules) are best for long files like background music or dialog, and uncompressed is better for short sound effects. Tweak the amount of Compression with the compression slider to just before the difference in sound quality is noticeable.
一般的經(jīng)驗(yàn)是孙蒙，壓縮音頻（或模塊）最好是長文件，如背景音樂或?qū)υ挶ǎ磯嚎s的用于短聲音效果更好挎峦。用壓縮滑動(dòng)條（Compression）來調(diào)整壓縮量，前后音質(zhì)的差異是明顯的合瓢。
Using 3D Audio 使用3D音頻
If an audio clip is marked as a 3D Sound then it will be played back to simulate its position in the game world's 3D space. 3D sounds emulate distance and location of sounds by attenuating volume and panning across speakers. Both mono and multiple channel sounds can be positioned in 3D. For multiple channel audio, use thespreadoption on theAudio Sourceto spread and split out the discrete channels in speaker space. Unity offers a variety of options to control and fine-tune the audio behavior in 3D space. Take a look atAudio Source.
