Time Stretching Audio Files in Soundtrack Pro

At first glance, SoundtrackPro may just seem like a cool way to create looped based music, but recently, GeniusDV has introduced Soundtrack Pro to Law Enforcement Agencies as a viable way to help their forensics department clean up audio that may be crucial to an investigation. That's right, SoundtrackPro can be used for more than just creating techno music and gunshots, but that's not all. Soundtrack Pro gives you the ability to time stretch audio files, allowing you to lengthen the duration of an audio project if it comes in just under the duration that it needs to be. This function works well if your project is coming in just short of the duration. Keep in Mind that if your project contains audio and if you have to perform a substantial stretch to make your project fit, you will be sacfrificing audio quality by way of tempo displacement and distortion. This effect can be applied to an entire audio project or just a section of it. In this excerise, we will only be applying the effect to a portion of a project. Use this function sparingly!

4 With the Time Stretch Tool active, drag the edge of the section that is highlighted. Dragging the edge to the right increases the duration of your project making the contents play back slower and dragging inward, to the left, will making the selection area shorter, decreasing the length of your program and allowing for a faster play back.
