When viewing the audio waveforms, what does the shape of the waveform indicate?

The shape of the audio waveform is a visual representation of the sound's amplitude over time. Each waveform displays how loud or soft the audio is at any given moment, making it a crucial tool for understanding the audio dynamics. When you analyze the waveform, you can detect volume changes — peaks indicate louder sounds while valleys represent quieter sections. This allows for precise editing, such as adjusting the mix, trimming silences, or identifying sections that might need enhancement or effects. The waveform acts as a guide for sound editing, enabling users to visualize the audio characteristics effectively throughout the track's duration.

While the other options may touch on aspects of audio production, they do not encompass the primary purpose of what the waveform shape signifies in audio editing.
