SonicFire Pro is a great application for adding sounds and sound tracks to animation. It comes with lots of professional sound loops and you can order more from an extensive catalog from our partners, SmartSound. If you downloaded our Vue 4 Pro demo movie, you heard a sample of what you can do. SonicFire lets you resize the tracks easily by sliding them in a timeline, so you can get exactly the right length to fit your movie. Both e-on software and Smartsound offer a bundle. Check it out.
