Apple Music revealed that it has been slowly rolling out Apple Digital Masters, an initiative that combines the company’s highly lauded “Mastered for iTunes” offering into one global catalog with unrivaled quality, for Apple Music and the iTunes Store.
Apple Digital Masters provide uncompromising studio sound, virtually indistinguishable from the original master recordings. With less noise and higher fidelity than ever, this is world-class audio for everyone. Apple Digital Masters combines cutting-edge technology, industry-wide best practices, and the best available artist master recordings to bring listeners unrivaled streaming audio and digital download experience.
By encoding from high-resolution masters, Apple music engineers are able to capture all of the detail of a recording in a size that is convenient for streaming and downloading. Using 24-bit files means less noise and higher encoding efficiency. Apple has distributed our industry-leading encoder for free to mastering engineers worldwide and by using these software tools engineers are able to create “test pressings” of exactly what the audience will hear. The result is music that is virtually indistinguishable from the original hi-res master recordings.
