Topspin allows you to edit metadata for any digital asset in your account. Audio Track metadata is the most commonly used metadata, as it determines what information shows up in media players like iTunes:
There are currently two methods for editing your Audio Track metadata within the Topspin application: editing one track at a time or "batch editing".
Batch Edit Metadata
In the Products tab, it's possible to edit multiple files simultaneously. To edit multiple tracks, just select 'Audio Tracks' in the 'View' drop-down.
Place a check next to the items that you'd like to edit and click "Batch Edit Metadata."
The Batch Edit form for you media will then open, allowing you to enter information that will be applied across all selected files.
Add an uploaded image to your product
To add artwork to your digital media, just make sure you've uploaded an image file to your account. You will be able to select an image from those you've uploaded. Your uploaded images will appear in a carousel under the "Artwork" panel, and may be dragged and dropped from the carousel to the space directly above. Once your image "sticks", save the panel.
Metadata Trick: iTunes Users
You can edit metadata for your audio files in the application, but you will find it much easier to do this by using the iTunes batch edit feature. To do this, you must convert your WAV or AIFF files to Apple Lossless inside iTunes. To confirm these controls, go into the Preferences > General > Import Settings and set conversion to Apple Lossless.
You can then select the files and edit the album artwork, metadata etc inside iTunes to guarantee that the album looks the way you want it. First, do a batch edit (select all of the album files) to add album name, artist, total number of tracks, and artwork.
Then select each individually to edit the track title and number.
Once you're satisfied with the results, select the files from the appropriate folder in your iTunes library and upload the files to your Topspin account.
