SoundCloud has partnered with online mastering company LANDR, meaning that users can now get free track optimization. LANDR was launched last year with supporters like Nas and Richie Hawtin, claiming to give tracks "a quality finish like any major label artist with a budget." The feature is free for every SoundCloud user, as long as they sign up for a LANDR account. While the deal won't offer free access to all of LANDR's services, they will optimize tracks specifically for streaming. Users wanting MP3 or WAV mastering will have to pay.

"We use exactly the same algorithms but we did some research to find the best output for optimising the sound of any track on the SoundCloud streaming format," a LANDR spokesman said. "The optimised tracks will only be hosted on SoundCloud and not in LANDR’s track library. It is really aimed at streaming on SoundCloud. If a user wants to get a proper master, they will have to buy it from LANDR in HD WAV, WAV or high or low-res mp3 formats."
