Apr 06, 2020 What is Audio MIDI Setup? Audio MIDI Setup is the native audio and MIDI utility app for macOS. You can see each connected device and some of its settings. Many audio devices have unique control panel software, so Audio MIDI Setup will just show you the basics. The MIDI window is similar, but can also show each devices’ input and output. Change the Format settings in Audio MIDI Setup to 96000.0 kHz and 2ch-24bit. Also, running the music through your Mac’s built-in audio hardware means you’re probably not getting all the.
When you use macOS Catalina's built-in screen recording you'll get audio only from the microphone. If you want to record the audio coming out of the system and apps, you'll need to install a third-party extension. One company provides an extension for free that you can use with their software or just with macOS QuickTime screen recording.

Audio MIDI Setup User Guide
Use Audio MIDI Setup to set up audio input and output devices, such as microphones and multichannel audio interfaces. You can also use it to route audio from iOS and iPadOS devices directly into your Mac.
Available settings in Audio MIDI Setup depend on the audio device you’re using. For example, you can adjust the volume for each channel your audio output device has available.
Audio Midi Setup Utility
Connect your audio devices to your Mac and, if necessary, install any software included with the devices.
In the Audio MIDI Setup app on your Mac, in the sidebar of the Audio Devices window, select a device.
Note: For iOS and iPadOS devices, first click Enable, then select the device. You may be asked to unlock your device with a passcode or to trust the device.
Control-click the device, or click the Action pop-up menu at the bottom of the sidebar, then choose how the device is going to be used:
For sound input: Choose “Use This Device for Sound Input.”
For sound output: Choose “Use This Device for Sound Output.”
For playing system sounds: Choose “Play Alerts and Sound Effects Through This Device.”
On the right side of the Audio Devices window, choose the options available for the device you selected:
In most cases, “Clock source” is set to the default.
Click the Format pop-up menu, then set the sample rate and bit depth. Make sure they match the appropriate settings for your audio device.
If your Mac supports the hardware sample rate converter, the Hardware Rate Converter pop-up menu is available in the Input pane. When you choose Automatic from the pop-up menu, the hardware sample rate converter is turned on if the audio samples coming in are PCM and formatted according to the international standard IEC 60958-3. The hardware sample rate converter is turned off if the input stream is encoded. You can also choose Enable or Disable from the menu, to keep the hardware sample rate converter turned on or off.
If software volume control is available for your device, the Volume sliders appear blue to indicate that they’re active. Drag the sliders to set the volume for each channel.
To set up a surround (multichannel) speaker configuration, click Configure Speakers, then set up the configuration.
