A "remaster" refers to the process of improving the quality of an existing piece of media, such as a video game, movie, or music album. This involves enhancing the audio and visual elements to make them clearer and more enjoyable for modern audiences. For example, a classic film might be remastered to have better picture resolution and sound quality, allowing viewers to experience it in a new light. Remastering can also include adding new features or content, like bonus tracks in a music album or updated graphics in a video game. This process helps preserve the original work while making it accessible and appealing to both new fans and those who loved it in its original form.
