让我们谈谈如何减少背景噪音并使用麦克风获得更好的声音。无论您是在通话还是录音，这些提示都会很有用。
我们将涵盖许多不同的领域，因此请务必仔细阅读每个部分。
完成阅读后，您将知道如何确保您的麦克风质量尽可能好。
从硬件开始
如果您真的关心获得更好的音质，那么您真的需要在更好的麦克风和一些设备上投入一点。谢天谢地，它真的只有一点点。例如，您可以以不到 50 美元的价格购买Blue Snowball Ice 。
然后，您可以在亚马逊(Amazon)上以不到 10 美元的价格获得一个好的麦克风支架或臂，并以类似的价格获得一个弹出过滤器。使用此设备，您将能够为自己设置一个麦克风，该麦克风可以专注于您的人声而不是其他任何东西。
不过，它不会停在你的麦克风上。您应该考虑如何设置办公室或游戏室，并考虑如何重新布置硬件，以使麦克风不会接收到按键、鼠标移动或其他小噪音。
您还应该考虑保持门窗关闭将如何有助于减少外部音频被拾取，并确保让与您住在一起的每个人都知道您正在录音并且需要一些安静的时间。
使用软件(Software)去除背景噪音(Background Noises)
如果您想获得最干净的音频，您可以更进一步，使用软件阻止麦克风拾取您的声音范围之外的噪音。
您可以使用噪音门来确保您的麦克风只有在听到一定分贝范围内的声音时才开始拾取音频。这非常适合阻止外面的风扇、汽车的嗡嗡声，甚至是在其他房间里说话。
没有适用于所有人的噪音门设置，因此您需要调整打开和关闭阈值，以便噪音门可以拾取您的声音，但没有其他功能，并且在您开始讲话时它不会被切断安静一点。
某些程序（例如OBS）在麦克风过滤器设置下内置了噪声门，但如果您需要Windows 10的系统范围选项，则有两个流行的选项。
第一个选项是NoiseBlocker，这是一款非常易于使用的噪声门软件，完全使用的费用为 9.99 美元，或者您可以每天免费使用 1 小时。NoiseBlocker 可以设置为主动收听特定的噪音并将其屏蔽掉。
另一个选项是NoiseGator，它是一个完全免费的替代品，但偶尔会出现一些令人沮丧的错误，通常会导致它停止工作。NoiseGator 可用于创建一个门，该门将阻止您的麦克风录音，除非声音落在设定的分贝范围内。
不幸的是，NoiseGator开发人员已经放弃了该项目，因此没有希望修复这些问题。然而，一些用户从未遇到过NoiseGator的问题，因此值得尝试两者来找出哪一个效果最好。
录制后清理音频
通常，在录制高质量音频时需要遵循一系列顺序。第一步是尽最大努力使用您的硬件获得最干净、最高质量的音频。这意味着创造一个安静的环境并正确设置您的麦克风。
如果您尽最大努力将背景噪音降至最低，说话清晰，并为您的房间隔音，您就不必担心事后尝试修复音频。下一步是使用NoiseGator或NoiseBlocker等软件来进一步减少背景声音。
如果即使在这一点上，您的音频还不完美，您也可以在一个名为Audacity(Audacity)的软件中免费清理它。我们将带您完成一些快速步骤，以确保您的声音尽可能干净，不会以任何方式对您的语音质量造成任何问题。
首先，免费下载 Audacity(download Audacity)。接下来，确保每次录音时，在开始讲话之前都有几秒钟的沉默。这将允许您捕获可以在Audacity中减少的声音配置文件，以消除任何剩余的背景噪音。
之后，请确保您尝试将录音保存在尽可能少的文件中。理想情况下，最好只有一个录音，因为这样可以更轻松地编辑和保持一致。您总是可以删除您犯错误并需要重复自己的区域。
考虑到这些提示，是时候打开Audacity了。进入(Once)Audacity后，单击文件、导入、音频。(File, Import, Audio. )导航到您要导入的音频，然后单击打开(Open)。
一旦打开，就该减少背景噪音了。首先(First)，单击并拖动( click and drag )时间线的开头以获得一个空白的声音区域。这应该是您在开始讲话之前录制的声音。它应该看起来像上图。
接下来，单击顶部工具栏中的效果(Effect)，然后单击降噪(Noise Reduction)。
将出现一个弹出窗口。在此窗口中，单击Get Noise Profile，确保空音频仍然突出显示。
接下来，按Ctrl+A选择整个音频剪辑。然后，单击效果(Effect)并再次单击降噪(Noise Reduction )。这一次，在确保整个剪辑突出显示并且噪点(Noise)位于“减少(Reduce)”选项上后，单击“确定”。(OK)现在将删除背景音频。
(Take a
listen through )通过单击播放按钮收听。如果您发现某些语音太大声或语音电平出现异常，您可以使用Effects
> Compressor.
使用上图作为一般语音的良好声乐设置的指导。如果总体上太安静或太响，您还可以使用Effects > Amplify”来提高或降低整体音量。
您使用的设置将取决于您希望自己的声音有多响，但通常增加或减少 3-10 分贝的范围足以使您的声音处于合理的水平。
完成后，您可以单击File > Export，然后单击导出(Export)为您选择的文件类型。默认情况下，您将拥有MP3、WAV和其他一些可用的音频文件。如果您不确定要使用什么，我建议您使用MP3。
概括
感谢您阅读我们的指南，了解如何减少背景噪音并使用麦克风获得更好的声音。如果您已经阅读到这里，您将知道如何改进硬件设置、安装软件以获得更好的声音，以及对已录制的音频进行更改以清理您的语音片段。

Microphone Tips: How to Reduce Background Noise and Get Better Sound
Lеt’s talk аbоut how you can reduce background
noise and get better sound with your microphоne. Whether you’re in a call or
recording yoυr voice, these tіps will be useful.
There are a number of different areas we will
cover, so make sure to read through each section carefully.
Once you’ve finished reading, you’ll know how
to make sure your microphone quality is as good as possible.
Start with Hardware
If you truly care about achieving better sound quality, you’ll really need to invest a little into a better microphone and some equipment. Thankfully, it really is only a little. You can pick up the Blue Snowball Ice for less than $50, for example.
You can then get a good mic stand or arm for less than $10 on Amazon, and a pop filter for a similar price. With this equipment, you’ll be able to set yourself up with a microphone that can focus on your vocals and not much of anything else.
It doesn’t stop at your microphone, though.
You should think about how you set up your office or gaming room and think
about how you can rearrange your hardware so that your microphone isn’t picking
up key presses, movements of your mouse, or other small noises.
You should also consider how keeping windows
and doors closed will help to reduce outside audio being picked up, and make
sure to let everybody that lives with you know that you are recording and need
some quiet time.
Using Software to Remove Background Noises
If you’d like to get the cleanest audio possible, you can go a step further by using software to stop your microphone from picking up noises outside of your vocal range.
You can use a noise gate to make sure your microphone only starts to pick up audio once it hears sounds within a certain decibel range. This is perfect for stopping the hum of fans, cars outside, or even talking in other rooms.
There’s no noise gate setting that works for everybody, so you’ll need to tweak the open and close threshold so that the noise gate picks up your voice, but nothing else, and also that it doesn’t cut off in case you start speaking a little quieter.
Some programs, like OBS, have a noise gate built in under the microphone filter settings, but if you need a system wide option for Windows 10, there are two popular options.
The first option is NoiseBlocker, a very easy to use noise gate software that either costs $9.99 for full use, or you can use it for free for 1 hour per day. NoiseBlocker can be set up to actively listen to specific noises and it will block them out.
The other option is NoiseGator, which is a completely free alternative, but there are occasionally some frustrating bugs that can often cause it to stop working. NoiseGator can be used to create a gate that will stop your microphone from recording unless sounds fall within a set decibel range.
Unfortunately, the NoiseGator developer has
abandoned the project so there’s no hope for fixes to these problems. Some
users have never had issues with NoiseGator, however, so it’s worth
experimenting with both to find out which one works best.
Cleaning Up Audio after Recording
Generally, there is a chain of order to follow
when it comes to recording high quality audio. The first step is to try your
hardest to get the cleanest, highest quality audio with your hardware. This
means creating a quiet environment and setting up your microphone correctly.
If you try your hardest to minimize background
noise, speak clearly, and soundproof your room, you won’t have to worry too
much about trying to fix the audio after the fact. The next step is to use
software like NoiseGator or NoiseBlocker to reduce background sounds even
further.
If, even at this point, your audio isn’t
perfect, you can clean it up for free in a software called Audacity. We’ll take
you through some quick steps to ensure your sound is as clean as possible,
without causing any issues with your voice quality in any way.
First, download Audacity for free. Next, ensure that each time you record, you have a few seconds of silence before you start speaking. This will allow you to capture a sound profile you can reduce in Audacity to eliminate any remaining background noise.
After, make sure you try to keep your
recording in as few files as possible. Ideally, it’s best that you have one
single recording, because it will make it easier to edit and keep consistent.
You can always cut out areas where you make mistakes and need to repeat
yourself.
With these tips in mind, it’s time to open Audacity. Once inside Audacity, click File, Import, Audio. Navigate to the audio you’d like to import and click Open.
Once opened, it’s time to reduce background
noise. First, click and drag the
beginning of the timeline to get an empty area of sound. This should be the
sound you recorded before you started speaking. It should look like the image
above.
Next, click Effect in the top toolbar and then click Noise Reduction.
A pop up window will appear. In this window, click Get Noise Profile, making sure that the empty audio is still highlighted.
Next, press Ctrl+A to select the whole audio clip. Then, click Effect and click Noise Reduction again. This time, click OK after making sure the whole clip is highlighted and Noise is on the ‘Reduce’ option. The background audio will now be removed.
Take a
listen through by clicking the play button. If you
notice some of your speech is too loud or there’s some abnormality in the
levels of your speech, you can use Effects
> Compressor.
Use the image above as a guideline for good vocal settings for general speech. If it’s too quiet or too loud, overall, you can also use Effects > Amplify to boost or reduce the overall volume.
The setting you use will depend on how loud you’d like your voice, but usually a range of a 3-10 decibel increase or decrease is enough to put your voice within a reasonable level.
Once you have finished, you can click File > Export, and then Export as a file type of your choice. By default, you’ll have MP3, WAV, and a few other audio files available. If you’re not sure what to use, I’d suggest MP3.
Summary
Thanks for reading our guide on how to reduce
background noise and get better sound with your microphone. If you’ve read this
far, you’ll know how to improve your hardware setup, install software to get
better sound, and make changes to already recorded audio to clean up your voice
clips.
