Audio mastering is a process of post-production enhancement and refinement of audio recordings. It is the final step in the production of a song, and involves an array of techniques to create a more professional and polished sound. Mastering helps to bring out the best in the audio, by adding clarity, punch, and depth.

The mastering process is distinct from mixing, as it focuses on the overall sound of the audio rather than on individual tracks. Mastering includes a range of tasks such as equalization, compression, limiting, noise reduction, and stereo imaging. These techniques help to clean up the sound and make it more consistent, while also increasing loudness, clarity, and punch. Mastering is a delicate art, and requires a skilled engineer to ensure the best results.
