Which feature allows you to upload your own sound files in EarSketch?

The Sound Browser is the feature that allows you to upload your own sound files in EarSketch. This tool is designed specifically for managing sounds and samples, making it easy for users to import custom audio files they want to integrate into their projects. By using the Sound Browser, you can enhance your music compositions with unique sounds, adding a personal touch to your creations.

The other features do not support the upload of sound files directly. The API browser is focused on providing access to various functions and methods for coding, while the Code Editor is where you write and edit your scripts for programming your music. The Share Browser is used for sharing your projects with others, but it does not facilitate file uploads.
