Who mastered Taylor Swift’s “august”?

Randy Merrill mastered Taylor Swift’s “august.”

Mastering is the final technical stage listed in the song’s personnel credits. It prepares the completed mix for release by refining its overall sound and ensuring it works consistently in distribution formats. Merrill’s credit comes after the recording and mixing roles in the production chain.

“August” was recorded at Kitty Committee in Los Angeles and Rough Customer in Brooklyn. Its mix was completed at Long Pond Studio in the Hudson Valley, New York, and its mastering took place at Sterling Sound in New York City. Those locations reflect the track’s multi-studio production process.

Merrill should not be confused with Jonathan Low, who mixed the song, or Laura Sisk, who handled recording. Jack Antonoff also had major production responsibilities, including the instrumental, but he was not the credited mastering engineer. The distinction matters because songwriting, production, recording, mixing, and mastering are separate credits.
