That is, of course, until Apple decides to make it a pricy add-on feature.

This is in contrast to the typical audio-out (or line-out) jack, which you might use to play sounds from your PC on external devices like a speaker system.

This is typically a weaker version of a normal line-in jack, as the input levels on a mic are usually at a much lower level than other types of input devices like audio amplifiers.

Standard line-in jacks can also be labeled mic-inthere isnt much difference between them.

Older Mac devices had a separate line-in jack for you to use for all audio input devices (including external microphones) and an audio-out jack for headphones and speakers.

This has been reduced to a single, switchable jack in modern Macs that allows you to use either.

To use it for line-in audio input, youll need to access your macOS System Preferences.

You can also click the System Preferences icon from the Dock to launch it instead.

Youll want to click on the Input tab to change your audio line-in settings.

This may look different, depending on your model of Mac device.

On a 2019 MacBook, for instance, an external microphone is detected using the Microphone port, but this may be listed as an Audio line-in port on older devices.

However, before you do that, you may wish to adjust the volume, as well as other settings such as the audio sample rates.

You can access this by clicking the Apple icon System Preferences Sound Input.

Reducing the volume on an external microphone, for instance, would reduce how loud any recorded sound would be.

Use your trackpad or mouse to move the slider left to reduce the volume or right to increase it.

Any detected sounds will appear in visual form in the Input level bar below it.

This is a core macOS app, which you can find by clicking the Launchpad icon on your Dock, clicking the Other folder, then pressing the Audio MIDI Setup icon to launch the app.

You can change the audio sample rate (shown in hertz) under the Format drop-down menu.

You can also change the input volume of your device here, under the Master Stream section.

Use your mouse or trackpad to move the slider left to decrease or right to increase.

Certain audio input devices may also come with their own control software, allowing you to further calibrate your input settings.

You might want to use it to record using two different microphones in GarageBand, for instance.
