Have you ever wanted to speed up or slow down a song or audio clip in Audacity? It’s a simple process that can make a big difference, whether you’re creating a remix or just trying to fit a song into a specific time frame. In this guide, we’ll show you how to use Audacity’s change tempo function to speed up your audio without distorting the sound quality.

To get started, select the entire track you want to edit by clicking CTRL + A. Then, go to the “Effect” menu and choose “Change Tempo.” This function allows you to adjust the audio speed without changing the pitch or tone of the sound.

To increase the speed of your audio, simply enter a percentage in the “Percent Change” box. For example, if you want to increase the speed by 20%, type “20” in the box. If you want to slow down the audio, enter a negative number.

It’s important to note that Audacity’s “Change Speed” function can produce a chipmunk-like sound when you speed up the audio. This can be undesirable if you’re looking for a natural sound. Instead, use “Change Tempo” to adjust the speed without distorting the sound.

Once you’ve entered the desired percentage change, click “OK” to apply the effect to your audio. You can then listen to the track to hear the difference. The “Change Tempo” function should produce a more natural sound than the “Change Speed” function, especially when trying to speed up audio.

In conclusion, using Audacity’s “Change Tempo” function is a great way to speed up or slow down your audio without compromising quality. With a few simple steps, you can edit your audio to fit your needs. Try it out and see how it works for you!
