Adjust Audio Speed Without Changing Pitch

Changing the speed of audio without affecting its pitch can be helpful, especially when you want to learn lyrics to a song or a new language from audiobooks.

VideoProc Vlogger allows you to adjust audio speed without changing pitch. Through the steps below, you'll learn how to do it. Let's download, install, and run VideoProc Vlogger.

Step 0 Create a new project

Launch VideoProc Vlogger. When a project panel pops up, complete the general settings to create a new project.

Step 1 Load audio to VideoProc Vlogger

Add an audio file (.mp3, .aac, .m4r, .ogg, etc.) from your computer to the media library, and then drag it to the timeline.

Step 2 Open Speed Editor

Click to select the audio track in the timeline. Open Speed Editor by clicking Speed in the toolbar.

Step 3 Adjust audio speed without changing pitch

The option, Change Pitch, is disabled by default, so you can keep the original pitch while adjusting audio speed.

Now you can change the audio speed in 3 ways:

Option 1. Adjust audio speed at a constant rate.

Select a preset speed effect among the 16 types of default speed effects without changing pitch.

Constant speed effect: 1/8, 1/4, 1/2, 2x, 4x and 8x. E.g. 2x will double the speed at a constant rate.

Option 2. Customize the audio speed.

Add points to the position where you want to apply speed effects in the audio. Then drag the curved lines between each two points to change the speed.

Option 3. Adjust audio speed with the preset speed effects.

Select a preset speed effect among the 16 types of default speed effects without changing pitch.

Variable speed effect: Montage, Heartbeat, Hero, Bullet, Jump, Fast In, Fast Out, Speed Up, and Speed Down. They are awesome effects that can achieve a curvilinear change of audio speed.

Step 4 Apply speed

Hit the blue button Apply to finish changing the audio speed. Then you'll be navigated to the main interface where you can proceed to edit or export the project from VideoProc Vlogger.
