To remaster audio and video, begin by transferring the original media to a high-quality digital format to preserve its integrity. For audio, use digital audio workstations (DAWs) to enhance sound quality through equalization, compression, and noise reduction. For video, employ video editing software to adjust color grading, resolution, and apply noise reduction techniques. Finally, export the remastered files in a suitable format for distribution or playback.
