Finding royalty free sounds of good quality is difficult. Aware of this, digifish music has uploaded a large number of sounds at the freesound project. All our sounds there are available for non-comercial projects under a worldwide, royalty-free, permanent and non-revocable license. Just follow the instructions at the top of the page after you find something you like from us.
OR click on a category, right -->
To download sounds you will need to create a (free) account.
We also have free music on Katie's page.
Have fun! :)
