Mastering is the final stage of the audio production process for film and video production. It involves enhancing and balancing the audio mix to create a uniform, polished and high-quality sound. In mastering, engineers use equalization, compression, and other techniques to bring out the best in the audio mix. They also add loudness and clarity, making sure that the audio is consistent and has the desired impact on the audience.
Mastering is essential for ensuring that the audio mix meets the technical standards of the film and video industry and will sound great on any playback system. The goal is to create a high-quality and cohesive sound that enhances the overall viewing experience.
