Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by the Walt Disney Studio and was released by Pat Powers, under the name of Celebrity Productions. The cartoon is considered the public debut of Mickey Mouse and Minnie Mouse, although both appeared months earlier in a test screening of Plane Crazy and the then unreleased The Gallopin' Gaucho. Steamboat Willie is the third of Mickey's films to have been produced, but it is the first to have been distributed, because Disney had seen The Jazz Singer (1927) and became determined to produce one of the first fully synchronized sound cartoons.
Steamboat Willie is one of the first cartoons with synchronized sound, and one of the first cartoons to feature a fully post-produced soundtrack, which distinguished it from earlier sound cartoons, such as Inkwell Studios's Song Car-Tunes (1924–1926), My Old Kentucky Home (1926), and Van Beuren Studios's Dinner Time (1928). Disney believed that synchronized sound was the future of film.
Mastering is a form of audio post production which is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device called a master recording, the source from which all copies will be produced (via methods such as pressing, duplication or replication). In recent years, digital masters have become usual, although analog masters—such as audio tapes—are still being used by the manufacturing industry, particularly by a few engineers who specialize in analog mastering.
Mastering requires critical listening; however, software tools exist to facilitate the process. Results depend upon the intent of the engineer, their skills, the accuracy of the speaker monitors, and the listening environment. Mastering engineers often apply equalization and dynamic range compression in order to optimize sound translation on all playback systems. It is standard practice to make a copy of a master recording—known as a safety copy—in case the master is lost, damaged or stolen.
