How do the sharing levels (public and private) work?

When you upload a sound to SoundCloud, you have two options for how you want to share it with other users. Public sharing means that anyone can listen to your sound. Private sharing is exclusive and you have complete control over who has access to your tracks and who doesn't. To change the settings, click on the pen icon below the waveform of the sound. Scroll down to "Settings" to configure.
