您的Mac配备了麦克风，可让您录制音频并通过FaceTime与人交谈。对于这些基本任务来说已经足够了。但是，如果您想录制专业音频或类似的东西，您需要考虑使用外部麦克风，因为内置Mac麦克风并不是最好的。
好消息是，如果您有 iPhone，则无需外接麦克风。您可以将 iPhone 用作Mac的麦克风。由于 iPhone 实际上是人们用来通话的电话，因此您可以依靠它的麦克风来完成大部分（如果不是全部）录音任务。
不过，将 iPhone 作为麦克风连接到Mac并不太简单。您需要通过一些设置选项并安装应用程序，然后才能在机器上使用 iPhone 录制音频。
在 Mac 上将 iPhone 用作音频输入(Use Your iPhone As An Audio Input On Mac)
您要做的第一件事是配置您的Mac，使其将连接的 iPhone 视为音频输入设备。默认情况下它不会这样做，但您可以启用一个选项，然后您的 iPhone 可以用作音频设备。
- 使用手机随附的原装数据线将 iPhone 插入Mac 。如果 iTunes 应用程序(Close the iTunes app if it automatically opens)在您连接 iPhone 时自动打开，请关闭它。
- 单击Dock中的Launchpad，搜索名为Audio MIDI Setup的应用程序，然后单击它以启动该应用程序。
- 当应用程序打开时，您会在左侧边栏中找到您的 iPhone。您还会在 iPhone 下方看到一个按钮。单击(Click)此启用(Enable)按钮以启用您的 iPhone 并将其用作Mac上的音频设备。
- 您将在列表中看到您的 iPhone 的新条目。该按钮现在应该显示禁用(Disable)，这意味着该功能当前已启用。
- 退出Mac上的(Mac)音频 MIDI 设置(Audio MIDI Setup)应用程序。
您的Mac现在认为您的 iPhone 是一个音频设备，您可以对其执行通常在音频设备（如耳机）上执行的任何操作。
在 iPhone 上安装和配置麦克风应用程序(Install & Configure a Microphone App On An iPhone)
尽管您的Mac将您的 iPhone 视为麦克风，但您仍然不能将其用于录音。这是因为您的 iPhone 不会在您未先触发麦克风的情况下立即发送任何麦克风信号。
实际上，官方 iOS App Store上有一个免费的应用程序应该可以帮助您做到这一点。它会触发你 iPhone 上的麦克风功能，让你的Mac捕捉到音频信号。
确保您的 iPhone 仍通过电缆连接到Mac 。
- 安装后启动应用程序。该应用程序中的功能并不多，您几乎不会在主界面上看到两个选项。点击前面的 iPhone 麦克风(Front iPhone Mic)以使用 iPhone 的前置麦克风。
- 然后点击显示无输出(No Output)的选项以选择从 iPhone 发送音频信号的位置。从屏幕上弹出的菜单中选择Dock Connector 。这可确保您的麦克风音频发送到连接到Mac的(Mac)Dock连接器。
将 iPhone 设置为 Mac 上的主要音频输入设备(Set An iPhone As The Primary Audio Input Device On a Mac)
您的 iPhone 是Mac的音频设备，但它仍然不是主要设备。您的Mac仍使用自己的麦克风作为音频输入，您需要将其更改为 iPhone。完成后，您的 iPhone 麦克风将成为您机器的主要麦克风。
- 单击(Click)屏幕左上角的Apple标志，然后选择(Apple)System Preferences。
- 在以下屏幕上选择声音(Sound)以打开声音设置菜单。
- 在声音设置屏幕上，单击顶部的输入选项卡。(Input)它会让你为你的Mac选择一个音频输入设备。
- 您的 iPhone 应该出现在音频设备列表中。单击(Click)它，它将成为您机器上的主要音频输入设备。
您无需手动保存更改，因为您的Mac会自动为您保存。

How To Use Your iPhone As a Microphone On a Mac
Your Mac сomes equіpрed with a miсrophone tо let you rеcord audio and talk to people oνer FaсeTime. It’s good enough fоr basic tasks like these. However, if you want to record professional audio оr anything likе that, you’ll want to сonsider using an external mіcrophonе as the built-in Mac microphone isn’t the best of the best.
The good thing is, if you have an iPhone, you don’t need to get an external microphone. You can use your iPhone as a microphone with your Mac. Since the iPhone is actually a phone that people use to talk, you can rely on its microphone for most, if not all, of your audio recording tasks.
Connecting an iPhone to a Mac as a microphone isn’t too straightforward, though. You’ll need to go through a few settings options and install an app before you can record audio with your iPhone on your machine.
Use Your iPhone As An Audio Input On Mac
The first thing you’ll want to do is configure your Mac in such a way that it considers your connected iPhone as an audio input device. It doesn’t do so by default but you can enable an option and your iPhone can then be used as an audio device.
- Plug in your iPhone to your Mac using the original cable that came with your phone. Close the iTunes app if it automatically opens when you connect your iPhone.
- Click on Launchpad in the Dock, search for the app named Audio MIDI Setup, and click on it to launch the app.
- When the app opens, you’ll find your iPhone listed in the left sidebar. You’ll also see a button beneath your iPhone. Click on this Enable button to enable and use your iPhone as an audio device on your Mac.
- You’ll see a new entry for your iPhone in the list. The button should now say Disable which means the feature is currently enabled.
- Exit out of the Audio MIDI Setup app on your Mac.
Your Mac now thinks your iPhone is an audio device and you can perform any action on it that you’d normally perform on an audio device such as a headphone.
Install & Configure a Microphone App On An iPhone
Although your Mac considers your iPhone as a microphone, you still can’t use it for audio recordings. It’s because your iPhone won’t send any microphone signals straightaway without you first triggering the mic.
There’s actually a free app on the official iOS App Store that should help you do it. It’ll trigger the microphone function on your iPhone and let your Mac catch the audio signals.
Ensure your iPhone is still connected to your Mac over a cable connection.
- Launch the iOS App Store on your iPhone.
- Search for an app named Microphone Live and install the app on your device when you find it.
- Launch the app when it’s installed. There aren’t many functions in the app and you’ll hardly see two options on the main interface. Tap on the one that says Front iPhone Mic to use the front microphone of your iPhone.
- Then tap on the option that says No Output to select where to send the audio signals from your iPhone. Choose Dock Connector from the menu that pops up on your screen. This ensures your microphone audio is sent to the Dock connector which is connected to your Mac.
- Keep the app open on your iPhone.
Set An iPhone As The Primary Audio Input Device On a Mac
Your iPhone is an audio device for your Mac but it’s still not the primary one. Your Mac still uses its own microphone as an audio input, which you need to change to your iPhone. Once that’s done, your iPhone microphone will be the primary microphone for your machine.
- Click on the Apple logo at the top-left corner of your screen and select System Preferences.
- Choose Sound on the following screen to open your sound settings menu.
- On the sound settings screen, click on the Input tab at the top. It’ll let you select an audio input device for your Mac.
- Your iPhone should appear in the list of audio devices. Click on it and it’ll become the primary audio input device on your machine.
You don’t need to save the changes manually as your Mac will do it automatically for you.
Use An iPhone As a Microphone On a Mac
Your iPhone is now connected to your Mac as a microphone and it’s all ready to be used for your audio recording tasks.
You can use any of the apps on your Mac to record audio with your iPhone as a microphone. Here we show how you can use a built-in and a free third-party app to record audio from an iPhone on your machine.
Record iPhone Audio Using QuickTime
QuickTime is the easiest way to record your iPhone screen as well as your iPhone audio. It’s free and comes preloaded on all Macs.
- Click on Launchpad in the Dock, search for QuickTime Player, and open the app.
- Click on the File menu at the top and select New Audio Recording.
- Click on the dropdown menu next to the record button and select iPhone from it.
- Hit the red record button to start recording with your iPhone microphone.
- Select the File menu followed by Save to save your audio file.
Record iPhone Audio Using Audacity
Audacity is a free and open-source app that helps record audio and tweak your existing sound files.
- Launch the Audacity app from Launchpad on your Mac.
- Select iPhone from the microphone dropdown menu so it uses your iPhone as a microphone.
- Click on the red record button to start the recording.
