Which types of rulers are considered time-based?

Time-based rulers in Pro Tools help users measure and navigate audio sessions relative to time. The correct answer, which includes Bars/Beats, Min:Sec, Samples, and Time Code, refers to specific ways of organizing and quantifying time within a project.

Bars/Beats is essential for music production, allowing for precise alignment with musical measures, while Min:Sec provides traditional time-based positioning in minutes and seconds. Samples are integral for achieving high precision in editing, as they relate to the smallest subdivisions of audio, and Time Code is crucial for synchronization purposes, especially in film and video work.

These rulers enable precise timing and placement of audio elements, making them indispensable tools for audio editing and production workflows. The other choices do not pertain specifically to time measurements in the context of audio editing and project management within Pro Tools.
