First, we’ll show you how it works on the web. You can change playback speed in both a web browser and in the YouTube mobile app for iPhone, Android, and iPad. How to Change YouTube’s Playback Speed on the Web Music will also play faster or slower without altering the musical key. Instead, it compresses or expands the audio and video samples to maintain the same audio pitch during playback-so it really just sounds like the same person is talking faster or slower.

If it did, a person’s voice might sound like a squeaky mouse when fast or like a lumbering giant when slow. YouTube’s playback speed feature doesn’t change the pitch of the video when you speed it up or slow it down. Likewise, if you’re watching a tutorial and things are moving too quickly, you can slow the video down so that you can keep up. If something seems like it’s taking forever-perhaps a long presentation, interview, or podcast where everyone is speaking slowly-you can actually speed it up. With “1” being normal speed, “0.25” is equal to a quarter of the original speed (slowing playback down), and “2” is twice as fast as normal. YouTube includes a feature called “Playback speed” that allows you to select a speed anywhere between 0.25 times and 2 times the normal speed. With over 8 million installs, it's the most downloaded time stretching and pitch shifting app on Google Play.How YouTube’s Playback Speed Controls Work
