It\u2019s in the interest of digital streaming platforms like Spotify and Apple Music to make sure that this doesn\u2019t happen on their services. In order to avoid this, they apply something called loudness<\/strong> normalization<\/strong>.<\/p>\n When you upload your track through a distributor, each streaming platform analyzes your audio for loudness. Then, it compares your music’s level to their loudness target<\/strong> and adjusts the gain of your audio accordingly. Different services have different loudness targets, though they largely tend to hover around -14 LUFS. This raises an interesting question: should you create multiple masters that are each tailored to a different streaming platform?<\/p>\n The simple answer is no; don’t worry about exporting multiple versions of the same track for different services (most distributors won’t even let you do this). Do<\/em> worry about mastering to a reference, using true peak normalization, and previewing the artifacts introduced by audio codecs. In the video below, we go over how to apply these techniques to your master using iZotope’s new Ozone 9<\/a>:<\/p>\n
