Audio Interface & Setting Gain
In this lesson we talk about how to use an Audio Interface with GarageBand. First, how to make sure that GarageBand recognizes the device, then how to set the gain for your guitar or microphone to ensure that your recorded signal is just right to avoid any background noise or clipping.
Once you have the gain settings dialed in, you can record with input monitoring selected, or you can record with the "direct monitoring" button enabled on your device for low-latency recording. Input monitoring gives you the advantage of being able to try out the plethora of available amp modeling software on GarageBand but invites the risk of latency on older or slower computers/devices. Once you record, you can playback your recordings through the amp modeling software.
This stuff is at the very core of how to get good recordings and have fun trying out the software effects that make GarageBand so inviting and helpful for creative music writing.
