Today's video tutorial comes from Ken Stone's FCP site, and covers time-stretching audio within Soundtrack Pro.
Occasionally, you get stuck with a chunk of audio, be it music or effects, that is just too short, or long. Since post production is all about making a tidy little package, it's important to ensure that all of the components fit just so, which is where time-stretching can come in handily.
Traditionally, altering the speed of an audio clip also altered its pitch. While this is useful for effects, it's detrimental when all you need is to fit a selection into a pre-determined time slot. Luckily, modern DAWs offer the ability to stretch time while maintaining the original pitch.
