Join Josh Harris for an in-depth discussion in this video What is time stretching/expanding?, part of Remixing Techniques: Time Stretching.
time stretching is the term frequently used by remixers when they talk about changing the BPM of a vocal. If you choose to increase the BPM of a vocal, then you're actually time-compressing the vocal so it will play faster than its original tempo. If you are slowing the vocal down, then you are expanding it, resulting in a vocal that will play longer in duration than the original. time stretching is one of the critical concepts to understand when it comes to remixing, and there are certain limitations as to how much you can speed up a vocal or how much you can slow it down.
For this course, I'll use the term Time Stretch to refer to changing our source audio's BPM in either direction unless I specify otherwise. It's important for me to point out that the time-stretching algorithms built into today's music software is significantly more advanced than the software that we used 7, 8, 9, 10 years ago, thereby allowing us to perform more drastic time stretches in either direction.
