What is a Soundbox? Similar to a favorites list or having multiple shopping carts at the same time that you can edit, take notes in and share with others. Create as many Soundboxes as you need for different projects or just for sounds you find interesting. As you move through the site looking for sounds for one project you may stumble onto something that would be good for another, just add it to one of your Soundboxes. You can add sounds from a Soundbox to the shopping cart at anytime.
