SoundCloud accounts are free to use, with more advanced creators able to upgrade to premium packages, featuring advanced statistics, controlled distribution and custom branding. SoundCloud users have access to a wide range of applications built on its API, enabling everything from mobile voice recording, online mastering, digital distribution and iPad music production.
