What action should you take to eliminate a popping sound at the end of an audio segment?

To eliminate a popping sound at the end of an audio segment, adding a 1 to 4 frame dissolve transition is an effective approach. This type of transition creates a gradual decrease in the audio levels at the end of the clip, which can soften abrupt cuts or sudden stops. The dissolve helps to blend the end of the audio segment with the preceding audio, effectively smoothing over any hard edges that could contribute to unwanted popping or clicking sounds.

By using a short dissolve, you ensure that the audio fades out gradually rather than cutting off abruptly, which is often the cause of pops. This technique is particularly useful in audio editing because it maintains the continuity and flow of the sound, allowing for a more polished and professional audio outcome.

While other options may address audio issues, they do not specifically target the popping sound like the dissolve transition does. Simply trimming the audio clip may result in a sudden stop, which could perpetuate the popping sound. Adjusting audio levels or adding a fade-out transition might help in some cases, but they may not be as effective as a dissolve for abrupt stops in audio.
