Whenever I use a sample, I typically make it from YouTube videos. For one, you can download them from places online, you can simply make your own, or you can buy premium sample and instrument packs like Komplete 13 from Native Instruments. There are a number of ways of creating samples. Click Share > Export Song to Disk > Desktop > AIFF, and then import the new file into the AUSampler by clicking Sine 110 Built-In and then Choose File, to select your file. To sample in Garageband, drag an audio file into the Workspace and use the (⌘ + T) tool to isolate the desired part. Fortunately for you, it’s a fairly simple process with just a few steps. In this tutorial, I’ll explain to you how to add samples to music in Garageband with a brief summary and then a step-by-step walk-through.
