Which tool is used for adjusting the gain of audio clips in Pro Tools?

The Trim Tool is utilized in Pro Tools to adjust the gain of audio clips effectively. This tool allows you to modify the level of an audio clip without affecting the overall track volume. When using the Trim Tool, you can click and drag directly on the waveform, which adjusts the gain of that specific clip while keeping the session organized and maintaining other settings intact. This method provides a straightforward way to change the audio level visually and efficiently.

Other options, like the Gain Tool, do not exist as a dedicated tool in Pro Tools. The Volume Tool is more associated with adjusting the track fader levels rather than modifying the clip gain itself. Similarly, the Fade Tool is primarily utilized for applying fades in and out of audio clips rather than adjusting their gain. The Trim Tool's unique function makes it the go-to option for this specific task.
