如果您想为播客、视频或其他媒体创建专业的声音，您可以使用(sounding voice)Audacity 中的许多工具，(Audacity,)这是一个免费的开源音频软件(source audio software)。在本指南中，我将解释您可以在Audacity中采取的步骤，以获得完美的专业声音(sounding voice)。
我还将提供一些关于挑选麦克风和其他设备的一般提示——一般来说，您需要投资大约 80 到 150 美元才能获得足以制作专业风格(style voice)录音的麦克风。
如果您已经有音频设备，请跳过第一部分。之后，请确保仔细执行每个步骤，以便获得最高质量的结果。
为专业声音(Professional Voice)挑选音频设备(Audio Equipment)
有数十种出色的麦克风可供选择，但对于预算选择，我建议以 50 美元购买Blue Snowball Ice Condenser 麦克风，以 70 美元购买(Blue Snowball Ice Condenser microphone)MXL Mics 770 心形电容麦克风(MXL Mics 770 Cardioid Condenser Microphone)，或以120 美元购买Blue Yeti。
选择好麦克风后，您还应该购买麦克风臂(microphone arm)。您可以将它连接到您的办公桌上，并确保在录制过程中您的麦克风直接位于您的嘴前。这些在亚马逊(These are available on Amazon)上售价 20-50 美元。
接下来，一定要购买一个爆音过滤器(pop filter)——它可以放在你的麦克风前面，以消除你说话时的爆音。这可以消除 Ps、Bs 或其他重击字母中的尖锐噪音。Pop filters can be purchased for under $10 on Amazon。
一旦你有了你的装备，你可以继续下面的步骤，开始在Audacity中创建一个专业的(Audacity)声音(sounding voice)。
如何在Audacity中提高(Audacity)录音质量(Your Voice Recording Quality)
在我们开始之前，您首先需要实际录制您的声音。录制声音以提高质量时，您必须遵循一些关键步骤。如果您不遵循这些步骤，那么使用软件改进您的录音将很困难。
首先，确保将背景噪音降至最低。有时很难减少每一种噪音——可以去除非常小的背景噪音，例如来自您的 PC 的噪音。但是，请尝试在录制过程中关闭台扇或空调等电器。
一旦你降低了声音，就该录制你的声音了。我个人发现Windows 10 Voice Recorder 应用程序(Voice Recorder app)可以完美运行。在开始菜单(Start Menu and click)中搜索录音机( Voice Recorder)，然后单击出现的选项。
录音机(voice recorder)打开后，就该开始录音了。单击麦克风按钮(microphone button )开始录制。将出现一个视觉效果，向您显示正在拾取声音。单击停止按钮(stop button )结束录制。如有必要，您也可以暂停，但我发现稍后在我的视频编辑软件中更容易消除错误。
对于每个录音，在开始讲话之前有30 秒的静默时间。(30 second period of silence )通过这种方式，您可以拾取环境的声音配置文件(sound profile)并使用 Audacity(environment and use Audacity)来减少它。
完成录音后，右键单击(right click the recording)录音机中的录音，然后单击打开文件位置(Open file location)。在Audacity(Audacity)的下一步中，您将需要此位置。
如果您还没有这样做，请下载Audacity。下载后，安装并打开它。
单击File > Import > Audio。接下来，导航到保存您的录音的文件夹，然后双击您的录音。
我们现在将按照以下步骤执行以下任务：
- 去除背景噪音。
- 均衡您的声音以获得更好的音频。
- 使用压缩器来减少声音的动态范围。
- 使用压缩器后放大您的声音以重新调整。
- 要消除背景噪音，请单击并拖动(click and drag)您在录音开始时录制的静音区域。当您拖动它时，它将突出显示。
- 接下来，单击Effect > Noise Reduction。
- 在降噪窗口(noise reduction window)中，单击获取噪声配置文件(get Noise Profile)。窗口将关闭。现在按Ctrl + A 选择整个录音(voice recording)。
- 再次单击Effect > Noise Reduction. 这次单击确定(OK )以根据您刚刚收集的噪声配置文件应用(noise profile)降噪。(noise reduction)
- 之后，按Ctrl + A再次选择整个录音。单击Effect > Equalization。您可以单击以在EQ 图(EQ graph)上添加点。
- 在大约75Hz 和 120Hz(75Hz and 120Hz)的低端（左侧）添加两个点( two points)。接下来，将75Hz(75Hz )处的点拖动到4dB标记附近。
- 在大约2500Hz(2500Hz )和3000Hz的高端（右侧）添加两个点(two points)。接下来，将3000Hz(3000Hz )处的点拖动到6dB左右。您可以单击预览(preview)来收听录音，并根据需要进行调整，但听起来应该已经更好了。
- 完成这些步骤后，单击Effect < Amplify ，然后使用默认级别单击确定。(OK)这将有助于在均衡后修复音频电平。
- 接下来，我们将使用压缩器效应(compressor effect)来降低较高分贝的区域并提升较低分贝的区域。单击Effect < Compressor。使用如下设置：
- 阈值：-30 分贝
- 本底噪声：-50dB
- 比例：5:1
- 攻击时间：0.10 秒
- 释放时间：1.0 秒
- (Tick Make-up gain)压缩后勾选 Make-up gain为 0 dB
- 最后，再次单击Effect < Amplify。这次，将放大 (dB) 级别设置为 -2.8(set the amplification (dB) level to -2.8)，然后单击“确定”。(OK.)
- 您现在可以播放音频。您应该听到比默认音频(default audio)有相当大的改进。要将录音保存为MP3，请单击File < Export < Export as MP3。
Make Your Voice Sound Professional With These Quick Audacity Tips
Іf you want tо сreatе a professional sounding νoice for podcasts, videos, or other media, you cаn use а nυmber of tools in Audacity, which is a free open source audio software. In this guide, I’ll explain the steps you can take in Audacity to get that perfect professional sounding voice.
I will also be giving some general tips on picking out a microphone and other equipment – generally speaking, you’ll need to invest around $80 to $150 to get a microphone that’s good enough to produce professional style voice recordings.
If you already have audio equipment, skip the first section. After, please make sure to follow each step carefully so you can get the highest quality results possible.
Picking Audio Equipment For a Professional Voice
There are dozens of great microphones available, but for budget options I would suggest purchasing a Blue Snowball Ice Condenser microphone for $50, a MXL Mics 770 Cardioid Condenser Microphone for $70, or a Blue Yeti for $120.
Once you have picked your microphone, you should also purchase a microphone arm. You can attach this to your desk and ensure your microphone is directly in front of your mouth during recording. These are available on Amazon for $20-$50.
Next, make sure to purchase a pop filter – this can be placed in front of your microphone to remove popping sounds when you speak. This can cut out sharp noises from Ps, Bs, or other hard hitting letters. Pop filters can be purchased for under $10 on Amazon.
Once you have your gear, you can move onto the steps below to start creating a professional sounding voice in Audacity.
How To Improve Your Voice Recording Quality In Audacity
Before we begin, you first need to actually record your voice. There are some crucial steps you must follow when recording your voice to improve the quality. If you do not follow these steps, improving your voice recording with software will be difficult.
First, make sure you reduce background noise to a minimum. Sometimes it can be difficult to reduce every noise – very small background noises, for example from your PC, can be cut out. However, try to switch off appliances like desk fans or your air conditioning during your recording.
Once you have reduced the sound, it’s time to record your voice. I have personally found the Windows 10 Voice Recorder app to work perfectly. Search Voice Recorder in the Start Menu and click on the option that appears.
Once voice recorder is open, it’s time to start recording. Click the microphone button to begin your recording. A visual will appear to show you that sound is being picked up. Click the stop button to end the recording. You can also pause if necessary, but I find it easier to cut out mistakes later in my video editing software.
For every recording, have a 30 second period of silence before you start speaking. This way you can pick up the sound profile of your environment and use Audacity to reduce it.
Once you have finished your recording, right click the recording in Voice Recorder and click Open file location. You’ll need this location for the next step in Audacity.
If you haven’t done so already, download Audacity. Once it has downloaded, install and open it.
Click File > Import > Audio. Next, navigate to the folder that your recording was saved and double click your recording.
We will now be following the steps below to do the following tasks:
- Remove background noise.
- Equalize your voice for better audio.
- Use a compressor to reduce the dynamic range of your voice.
- Amplify your voice to readjust after using the compressor.
- To remove background noise, click and drag the area of silence you recorded at the start of your voice recording. It will be highlighted as you drag it.
- Next, click Effect > Noise Reduction.
- On the noise reduction window, click get Noise Profile. The window will close. Now press Ctrl + A to select the entire voice recording.
- Once again, click Effect > Noise Reduction. This time click OK to apply the noise reduction based on the noise profile you just collected.
- After this, press Ctrl + A to select the entire voice recording again. Click Effect > Equalization. You can click to add points on the EQ graph.
- Add two points on the low end (left side) at about 75Hz and 120Hz. Next, drag the point at 75Hz to around the 4dB mark.
- Add two points on the high end (right side) at about 2500Hz and 3000Hz. Next, drag the point at 3000Hz to around 6dB. You can click preview to hear the recording, and make adjustments as necessary, but it should sound better already.
- After following these steps, click Effect < Amplify and then click OK with the default levels. This will help to fix up the audio levels after the equalization.
- Next, we will use the compressor effect to lower the higher decibel areas and bring up the lower decibel areas. Click Effect < Compressor. Use the settings as follows:
- Threshold: -30 dB
- Noise Floor: -50dB
- Ratio: 5:1
- Attack Time: 0.10 secs
- Release Time: 1.0 secs
- Tick Make-up gain for 0 dB after compressing
- Finally, click Effect < Amplify again. This time, set the amplification (dB) level to -2.8, then click OK.
- You can now play the audio back. You should hear a considerable improvement over the default audio. To save the recording as an MP3, click File < Export < Export as MP3.
