In EarSketch, what is the purpose of the 'visualization tools'?

The purpose of the 'visualization tools' in EarSketch is to help users see the audio waveforms and the overall structure of their compositions. These tools provide a visual representation of sound, allowing users to analyze and manipulate their audio more effectively. By visualizing the waveforms, users can understand dynamics, timing, and arrangement within their pieces, which is crucial for making informed edits and enhancements.

Other options, such as creating animated music videos or enhancing sound quality, do not align with the primary function of visualization tools in this context, as they focus more on visual elements or audio fidelity rather than providing insight into the audio components themselves. Additionally, providing lyrics is unrelated to the function of visualization tools, as they are specifically designed to represent audio rather than textual content.
