Apple Music has seen a significant increase in the popularity of Spatial Audio tracks since its launch in 2018. More than 90 percent of Apple Music listeners have chosen Spatial Audio over the standard format, and the number of Spatial Audio tracks has increased by 5,000 percent since the launch. To further support this format, Apple has decided to increase the royalty rate for Spatial Audio tracks by up to 10 percent starting in January. This increase is meant to reward higher quality content and ensure that artists are compensated for the time and investment they put into mixing in Spatial. Additionally, Apple has a quality control process in place to flag content that does not meet the Spatial Audio specifications and standards of quality. This move by Apple shows a commitment to maintaining the integrity and quality of the Spatial Audio experience for Apple Music subscribers.
