Mac Audio MIDI Setup at 96 kHz: Practical Guide

Before you start

This procedure uses the built-in Audio MIDI Setup utility in macOS. It runs locally on the Mac and does not require an internet service. You need an audio device that supports a 96 kHz sample rate, such as a compatible USB audio interface, Thunderbolt interface, or selected built-in Mac output hardware. Check the manufacturer’s specification for the device before changing the sample rate. Close apps that are actively using the audio device, especially voice or video call tools, audio editors, and media players, because some apps may lock the device to their own sample rate.

Step-by-step instructions

1) Connect the input device or output device that you want to use and confirm that macOS recognizes it. If the device has its own control software, install it first according to the manufacturer’s instructions.

2) Open Audio MIDI Setup. In Finder, choose Go, then Utilities, and open Audio MIDI Setup. You can also open it from Spotlight by typing Audio MIDI Setup.

3) In the sidebar, select the audio device that you want to change. This can be a built-in output, an external interface, or another connected device.

4) Click the Output button or Input button for that device depending on which path you want to configure. Some devices allow separate input and output settings, while others use one shared setting.

5) In the Format menu, choose 96,000 Hz. The sample rate options available depend on the device driver. If 96 kHz is not listed, the connected device or its current driver does not expose that sample rate to macOS.

6) Keep the bit depth option that is supported by the device and the app you plan to use. Common choices may include 24-bit integer or 32-bit float, but the exact labels vary by device and macOS version. Do not select a combination merely because it appears in the menu; it must be supported by the hardware and the recording app.

7) Check the input level for the selected input path if you are configuring a microphone or line input. Audio MIDI Setup may show an input level meter on supported versions and devices. Speak or send a test signal only after the sample rate and bit depth are set.

8) Close Audio MIDI Setup and reopen the app that will use the device. In that app, select the same device and matching sample rate if the app has its own audio settings. Mismatched app settings can override or conflict with the system setting.

Check the output

Reopen Audio MIDI Setup and select the device again. Confirm that the Format field still shows 96,000 Hz for the path you changed. Then open the app that will play or record audio and confirm that it reports the same sample rate or that it accepts the device’s current format.

Play familiar audio at a moderate volume. Listen for dropouts, clicks, digital noise, or unexpected changes in speed. A file with a different native sample rate may still be converted by the system, so playback alone does not prove that the file was created at 96 kHz. For recording, make a short test recording and inspect the file’s sample rate in the recording app or in a media information tool. Keep in mind that a higher sample rate creates larger files and uses more processing power and bandwidth in a video call or audio recording application.

Common problems and next steps

If 96 kHz is missing from the Format menu, the device driver may only report another sample rate to macOS. Use the manufacturer’s control panel to check whether the device needs its own sample rate setting. For some interfaces, the system menu only changes after the vendor utility or firmware option has been configured.

If you hear no sound after changing the device, quit the app that was using it and reopen it. Some apps continue using the previous sample rate until they are restarted. Also check that the correct output device is selected in the app and that the system output volume is not muted.

If you hear clicks, stutters, or background noise, lower the load on the Mac and the audio interface. Close unnecessary apps, disconnect other bus-powered devices if the interface is bus-powered, and try a different cable or port. A higher sample rate requires stable timing from the device, so an unreliable connection is more likely to produce audible problems than at 44.1 or 48 kHz.

If a voice or video call app forces the sample rate back to a different value, check that app’s audio settings. Many communication apps use their own audio pipeline and may not honor the system sample rate. For calls, using a matching supported rate in the app may be more reliable than trying to force the system setting to 96 kHz.

To return to the previous state, reopen Audio MIDI Setup, select the same device and path, and choose the earlier sample rate from the Format menu. This is reversible at any time unless a vendor utility has its own synchronized setting that must be changed there as well.
