In the macOS environment, the concept of "dispositivos de múltiplas saídas" (multiple output devices) can be closely related to the creation and management of Aggregate Devices and Multi-Output Devices. These features allow users to combine multiple audio devices into a single virtual device, enabling simultaneous audio output to multiple devices. This is particularly useful for audio professionals, podcasters, and anyone needing to distribute audio across several outputs.

Aggregate Devices combine multiple audio interfaces to work as one, while Multi-Output Devices allow audio to be played through several output devices at once. This article will guide you through the steps to create and manage these devices on macOS.

Examples:

1. Creating an Aggregate Device:

   • Open the "Audio MIDI Setup" application found in the Utilities folder within Applications.
   • Click the "+" button at the bottom left corner and select "Create Aggregate Device."
   • In the right pane, check the boxes next to the audio devices you want to include in the Aggregate Device.
   • You can rename the Aggregate Device by double-clicking on its name in the left pane.
   • Configure the sample rate and clock source if necessary.

2. Creating a Multi-Output Device:

   • Open the "Audio MIDI Setup" application.
   • Click the "+" button at the bottom left corner and select "Create Multi-Output Device."
   • In the right pane, check the boxes next to the audio devices you want to include in the Multi-Output Device.
   • You can rename the Multi-Output Device by double-clicking on its name in the left pane.
   • Set the Master Device and adjust the drift correction settings if needed.

3. Using Terminal to List Audio Devices:

   • Open the Terminal application.
   • Use the following command to list all audio devices:

     system_profiler SPAudioDataType

   • This command will provide detailed information about all audio devices connected to your Mac.

4. Setting the Default Audio Device via Terminal:

   • Open the Terminal application.
   • Use the following command to set the default audio device (replace "Device Name" with the actual name of your device):

     sudo osascript -e "set volume output volume 100" -e "set volume output device \"Device Name\""
