On Web, you can download tracks once you have signed in to your SoundCloud account by clicking on the download file button beneath the waveform.
You can enable, or disable downloads for your listeners through your track's Permissions tab. Enabling downloads means that your listener can have a copy of your original file format that you have uploaded to SoundCloud.
Please note: Not all tracks are downloadable. If you don't see a download file button, it means the user who uploaded it did not intend for it to be downloadable. Additionally, only individual tracks can be downloaded and playlists as a whole are not available.
Saving content on mobile devices
It is not possible to download a track from a mobile device. However, users with a SoundCloud Go or Go+ subscription can save content for offline listening on a mobile device.
