Garageband Sample Rate

Yes, GarageBand can record at 48 kHz. By default, GarageBand records audio at 44.1 kHz, but you can change the sample rate to 48 kHz for your project. Here's how you can do it:

Changing the Sample Rate in GarageBand

Open GarageBand:

• Launch GarageBand on your Mac.

Create or Open a Project:

• Either start a new project or open an existing one.

Open the Audio/MIDI Preferences:

• Go to the GarageBand menu at the top of the screen and select Preferences.
• In the Preferences window, click on the Audio/MIDI tab.

Change the Sample Rate:

• GarageBand itself does not have a direct option to change the sample rate within the project settings. However, you can achieve 48 kHz recording by ensuring that your audio interface is set to 48 kHz.
• Connect your audio interface to your Mac and open the Audio MIDI Setup utility (found in Applications > Utilities).
• In the Audio MIDI Setup, select your audio interface from the list of devices.
• Set the sample rate to 48 kHz for both input and output.

Restart GarageBand:

• Close GarageBand and reopen it to ensure it recognizes the new sample rate setting from your audio interface.

Verifying the Sample Rate

To ensure that your recordings are being captured at 48 kHz, you can check the following:

Project Information:

• In GarageBand, go to the Track menu and select Show Master Track.
• Click on the Master Track and then on the Track Info button (the "i" button).
• In the Track Info pane, look for the sample rate information.

Export Settings:

• When you export your project, you can set the export sample rate.
• Go to Share > Export Song to Disk.
• In the export dialog, choose your desired format and set the sample rate to 48 kHz if it’s not already selected.

Additional Notes

Audio Interfaces:

• Some built-in Mac audio hardware might not support 48 kHz, so using an external audio interface that supports 48 kHz is recommended.

Project Consistency:

• Ensure all imported audio files are at the same sample rate (48 kHz) to avoid any potential issues with playback quality or synchronization.

By following these steps, you can successfully record and produce audio at 48 kHz in GarageBand, allowing for higher fidelity recordings suitable for various professional applications.
