mac实时麦克风
Apple MacBooks and many desktop Macs have built-in microphones. However, you can also connect headsets and other mics via USB, a 3.5mm audio jack, or Bluetooth. Here’s how to fix a microphone that’s not working on your Mac.
苹果MacBook和许多台式Mac都具有内置麦克风。 但是，您也可以通过USB，3.5毫米音频插Kong或蓝牙连接耳机和其他麦克风。 这是修复Mac上无法使用的麦克风的方法。
找出您的Mac正在使用哪个麦克风 (Figure Out Which Microphone Your Mac Is Using)
To effectively troubleshoot microphone problems, it’s important to know which one your computer is using.
为了有效地解决麦克风问题，了解您的计算机正在使用哪一台计算机很重要。
Your Mac will be using one of the following:
您的Mac将使用以下之一：
-
The Internal microphone: Included in any MacBook or iMac.
内部麦克风：所有MacBook或iMac中都随附。
-
An external USB microphone: Connected directly to a USB port and self-powered.
外部USB麦克风：直接连接到USB端口并自行供电。
-
An External 3.5mm microphone: Connected to your computer’s microphone input or a separate audio interface, which might require additional power.
外部3.5毫米麦克风：连接到计算机的麦克风输入或单独的音频接口，这可能需要额外的电源。
-
AirPods or a similar Bluetooth headset: Connected wirelessly to your Mac.
AirPods或类似的蓝牙耳机：无线连接到Mac。
If you want to use your Mac’s internal microphone, you can move on to the next step. If you’re using a USB microphone, connect it directly to your Mac (avoid using a hub).
如果要使用Mac的内置麦克风，则可以继续进行下一步。 如果您使用的是USB麦克风，请将其直接连接到Mac(避免使用集线器)。
If you’re using a wired microphone that requires a 3.5mm stereo jack, make sure it’s connected to the right port, and that it doesn’t require additional power (it won’t work if it does).
如果您使用的有线麦克风需要3.5mm立体声插Kong，请确保将其连接到正确的端口，并且不需要额外的电源(如果需要，则无法使用)。
Finally, pair your AirPods or Bluetooth headset under System Preferences > Bluetooth. If you can’t get your Bluetooth headset to work, unpair it by clicking the “X” next to it in the “Devices” list. Then, try to pair it again.
最后，在“系统偏好设置”>“蓝牙”下将AirPods或蓝牙耳机配对。 如果无法使蓝牙耳机正常工作，请在“设备”列表中单击旁边的“ X”以取消配对。 然后，尝试再次配对。
Once you’re confident your chosen microphone is connected and powered on, it’s time to take a look at the audio settings.
一旦确定所选的麦克风已连接并打开电源，就可以查看音频设置了。
检查声音输入设置 (Check the Sound Input Settings)
A common cause of microphone problems is a misconfigured sound input. Head to System Preferences > Sound, and then click the “Input” tab. You should see a list of devices you can use as a sound source, including, (hopefully) the microphone you want to use.
麦克风问题的常见原因是声音输入配置错误。 转到系统偏好设置>声音，然后单击“输入”选项卡。 您应该看到可以用作声源的设备列表，包括(希望)要使用的麦克风。
To use a device, such as “Internal Microphone,” click it. If everything goes according to plan, you should see the bars fill up next to “Input Level” as you speak.
要使用设备，例如“内置麦克风”，请单击它。 如果一切都按计划进行，您将在讲话时看到“输入级别”旁边的条形填充。
If you don’t see anything, increase the “Input Volume” slider and try speaking again. If the slider is too low, your Mac won’t detect any sound.
如果看不到任何内容，请增加“输入音量”滑块，然后重试。 如果滑块太低，则Mac将无法检测到任何声音。
If you want to use your AirPods as your microphone, select “AirPods” from the list. If you’re using an audio interface, select it from the list.
如果要将AirPods用作麦克风，请从列表中选择“ AirPods”。 如果您使用的是音频接口，请从列表中选择它。
You might also see entries for other apps you have installed, like “Soundflower” or “Aggregate Device,” but you don’t want to use any of those right now.
您可能还会看到已安装的其他应用程序的条目，例如“ Soundflower”或“ Aggregate Device”，但您现在不想使用其中任何一个。
If you see movement in the “Input Level” indicator, that’s a good sign, but more troubleshooting might be necessary to get things working properly.
如果您在“输入电平”指示器中看到移动，这是一个好兆头，但是可能需要进行更多故障排除才能正常工作。
检查麦克风权限 (Check the Microphone Permissions)
Another common cause of microphone problems is Apple’s expanded permissions system. It prevents apps from accessing the microphone until you specifically allow it. When apps want to access the microphone, a notification should appear asking you to approve or deny the request.
麦克风问题的另一个常见原因是Apple的扩展权限系统。 除非您特别允许，否则它会阻止应用访问麦克风。 当应用程序要访问麦克风时，应显示一条通知，要求您批准或拒绝该请求。
If you deny the request, the app won’t be able to access the computer’s mic. It’s often a good idea to deny apps access to your hardware until you’re confident it needs it to function properly.
如果您拒绝该请求，则该应用将无法访问计算机的麦克风。 在您确信应用程序无法正常运行之前，最好拒绝应用程序访问您的硬件。
Head to System Preferences > Security and Privacy > Privacy, and select “Microphone” from the sidebar. You should see a list of apps that have requested access to your microphone. Any you have approved will have a checkmark next to them, while those you’ve denied will not.
转到系统偏好设置>安全和隐私>隐私，然后从边栏中选择“麦克风”。 您应该看到已请求访问麦克风的应用程序列表。 您批准的所有项目旁边都会有一个勾号，而您拒绝的那些则不会。
Click the Padlock icon at the bottom left to authenticate with your admin password (or Touch ID, or Apple Watch prompt). You can then approve or deny permission as you see fit by checking or unchecking the boxes next to the apps.
单击左下角的挂锁图标，以使用您的管理员密码(或Touch ID或Apple Watch提示)进行身份验证。 然后，您可以通过选中或取消选中应用旁边的框来批准或拒绝许可。
删除有问题的应用 (Delete Problematic Apps)
With the right source selected and any required permissions granted, your microphone should work. Try talking to Siri to test things out. If a specific app isn’t working, it might be the source of the problem.
选择正确的信号源并授予所有必需的权限，您的麦克风应该可以工作。 尝试与Siri交谈以测试情况。 如果某个特定的应用程序无法正常工作，则可能是问题的根源。
You can try checking the app’s preferences to see if there are separate settings for input devices. Apps like Adobe Audition and Audacity allow you to specify an input device separate from the one selected in the audio “Input” settings under “System Preferences.”
您可以尝试检查应用的首选项，以查看输入设备是否有单独的设置。 诸如Adobe Audition和Audacity之类的应用程序允许您指定输入设备，该输入设备与在“系统偏好设置”下的音频“输入”设置中选择的设备分开。
If everything seems fine, try deleting and reinstalling the app. Look for an updated version to download, just in case the issues were caused by incompatibility. Apple has made serious changes to the macOS permissions system over the last few revisions, so some outdated apps might not work.
如果一切正常，请尝试删除并重新安装该应用程序。 寻找更新的版本下载，以防万一问题是由不兼容引起的。 在最近的几个修订中，Apple对macOS权限系统进行了重大更改，因此某些过时的应用程序可能无法正常工作。
If you can’t get the app to work, it might be time to replace it with a similar one that does.
如果您无法使该应用程序正常运行，则可能是时候将其替换为类似的应用程序了。
重置NVRAM / PRAM (Reset the NVRAM/PRAM)
Non-volatile RAM (NVRAM) or parameter RAM (PRAM) is the type of memory your Mac uses to remember settings, such as the time and date and current volume settings. These settings persist even after your Mac has been powered off. Sometimes, problems can arise, and resetting the NVRAM/PRAM might help.
非易失性RAM(NVRAM)或参数RAM(PRAM)是Mac用来记住设置(例如时间和日期以及当前音量设置)的内存类型。 即使关闭Mac电源，这些设置仍然存在。 有时可能会出现问题，并且重置NVRAM / PRAM可能会有所帮助。
Since this memory deals specifically with volume and sound settings, it’s particularly pertinent to microphone issues. How you reset it depends on which Mac you have, but you can learn how to do so on your particular model here.
由于此内存专门处理音量和声音设置，因此与麦克风问题特别相关。 如何重置它取决于您拥有的Mac，但是您可以在此处了解如何在特定型号上进行重置。
尝试启用听写 (Try Enabling Dictation)
It’s a wild card, but some reports claim that enabling the macOS Dictation feature can help clear up some microphone issues, particularly those relating to the internal one. It’s unclear how this helps, but if you’ve gotten this far and your mic still isn’t working, it’s worth a shot.
这是一个通配符，但是一些报告声称启用macOS Dictation功能可以帮助清除某些麦克风问题，尤其是与内部麦克风有关的问题。 尚不清楚它如何提供帮助，但是如果您已经走了这么远而您的麦克风仍然无法正常工作，那么值得一试。
Head to System Preferences > Keyboard, and then click the “Dictation” tab. Click the “On” radio button and wait for any downloads to complete. Make sure the microphone you want to use is selected in the drop-down menu. If everything is configured correctly, you should see the levels moving.
转到“系统偏好设置”>“键盘”，然后单击“听写”选项卡。 单击“打开”单选按钮，然后等待所有下载完成。 确保在下拉菜单中选择了要使用的麦克风。 如果一切配置正确，您应该会看到级别移动。
If you haven’t used it before, you might want to take this opportunity to try out your Mac’s Dictation feature. By default, you can trigger it by double-pressing the Function (Fn) key. You can also control the rest of your Mac with your voice, thanks to Apple’s extensive accessibility features.
如果您以前从未使用过它，则可能想借此机会试用Mac的Dictation功能。 默认情况下，您可以通过双击功能(Fn)键来触发它。 借助Apple广泛的辅助功能，您还可以用声音控制Mac的其余部分。
检查外接麦克风的电平 (Check the Levels on Your External Microphone)
Most external microphones allow you to change levels directly on the mic, while others have a Mute toggle. Check your microphone over thoroughly to make sure the gain is turned up enough and that you haven’t accidentally muted it.
大多数外部麦克风允许您直接在麦克风上更改音量，而其他麦克风则具有静音开关。 彻底检查麦克风，以确保增益调高到足够程度，并且您没有意外将其静音。
If you’re using an audio interface, you might need to adjust the gain there.
如果您使用的是音频接口，则可能需要在那里调整增益。
重新启动Mac (Restart Your Mac)
Sometimes, you just need to turn it off and back on again to resolve any problems. You could also try installing any pending macOS updates under System Preferences > Software Update. Or, upgrade to the latest version of macOS, if you haven’t already done so.
有时，您只需要关闭然后重新打开即可解决任何问题。 您也可以尝试在“系统偏好设置”>“软件更新”下安装所有待处理的macOS更新。 或者，如果尚未升级，请升级到最新版本的macOS。
