The Soundtrack tool offers users an on-demand and highly intuitive interface for mixing music and video. The tool allows users to upload their own video files, search a database of royalty-free music, and mix a selected audio track with their video. Users have a variety of settings for adjusting the mix, such as in/out points and custom audio fade settings, and the tool supports almost all standard video codecs. The Soundtrack tool exports the final mix as a single FLV, allowing for easy integration with a number of online video services. PumpAudio was recently purchased by Getty Images.
