What is the method for automatically generating keyframes for the amplitude of an audio track?

The method for automatically generating keyframes for the amplitude of an audio track is to utilize the "Convert Audio to Keyframes" feature. This process analyzes the audio’s waveform and creates a set of keyframes based on the audio's amplitude levels. By selecting the audio layer, right-clicking, and navigating to Keyframe Assistant, you initiate this automatic generation, resulting in a new layer containing three sliders: Both Channels, Left Channel, and Right Channel, which represent the audio's volume over time as keyframes.

This technique is particularly useful because it allows animators and editors to synchronize visual elements with audio, effectively enhancing the visual storytelling without the need for manual keyframe placement, which can be both time-consuming and less precise.

The other options do not provide a method for automatic keyframe generation; adding keyframes manually requires precise timing and can be labor-intensive. Using the audio waveform is a great way to visualize the audio, but it does not directly generate keyframes. Lastly, applying audio transition effects can enhance audio playback but does not relate to keyframe generation for amplitude control.
