Signed downloads and file checks

Download a held track as a signed WAV and check a WAV's audio and signatures from the Jukebox.

Download signed WAV turns a track in your library into an audio file you can play outside Glob Social. The file includes a signed record of the saved track version and its credited accounts. The Jukebox also lets you check a WAV later.

For the Studio's song, loop, stem and audio-format export controls, see Exporting audio.

Download a track you hold

You can download a track you created, collaborate on, bought or saved while it was free. A preview alone does not provide a download.

  1. Open Library in the Jukebox.
  2. Find the track and choose its download icon, labelled Download signed WAV.
  3. Keep the page open while the track renders and the file is signed.
  4. Save the resulting WAV when your browser starts its download.

For a track you created or collaborate on, Settings also contains a text Download signed WAV button. Bought and saved tracks have the download icon on their library row.

The control shows Getting the track, then Signing the file. The accompanying message says Rendering, signing and adding the hidden mark. This can take a minute. A Jukebox download renders the full saved song; it does not use the Studio's current loop selection or unsaved edits.

Before download starts, Glob checks that the returned file's audio and signatures match its saved track version and registered signing keys. The file name comes from the track title, with characters unsuitable for that name removed, followed by .wav.

What is signed

A digital signature is a cryptographic seal used to check a record for changes. Glob adds signatures using the accounts credited on the saved track version. The record identifies the track, version and project and describes the exported audio.

The export also adds a hidden mark that can link the audio to its track and version. Treat a successful signature check and a detected hidden mark as separate results. A hidden mark can be found in a file whose signed record is absent, and that does not turn an unsigned file into a valid signed one.

Changing or converting the audio can prevent an exact signature check from passing. A detected mark does not promise that a file will remain identifiable after compression, cropping or other editing. The signatures also do not decide whether someone has the rights to publish a composition. Read the Terms of Service for the conditions of use.

Check a WAV

  1. Open the Jukebox.
  2. Expand Verify a file at the bottom of the window.
  3. Choose Check a music file.
  4. Select the WAV to check.

The chooser accepts WAV files. Supported audio is 16-bit PCM at 44.1 or 48 kHz, mono or stereo, up to 20 minutes. While the check runs, it says Checking file….

The check sends the selected file for verification. For information about handling uploaded data, read the Privacy Policy.
