What does the 'Track Freeze' feature help accomplish?

The 'Track Freeze' feature in Pro Tools is designed to help manage CPU resources more efficiently when working with sessions that have multiple tracks and effects. When you freeze a track, Pro Tools renders the effects and the audio into a single audio file. This process temporarily disables the real-time processing of any effects on that track, which reduces the demand on your CPU. By doing so, it allows for smoother playback and editing, especially in sessions with heavy processing. This makes it particularly useful for maintaining performance without sacrificing sound quality during the creative process.

While options like backing up audio settings, exporting tracks, or merging sessions may be valuable features, they do not directly relate to the core function of 'Track Freeze,' which primarily focuses on optimizing CPU performance and streamlining workflow.
