Part 2. How to Change Speed Online

If you don’t want to download the third-party program, another convenient way to change audio speed is by using an online editor like Audio Speed Changer. It can change the playback speed and key of music independently.

Step 2: Input the values in “Pitch change in semitones” or “Playback speed in percent” according to your needs.

Step 3: Once you’ve done, choose the output format and method, here it provides two different algorithms(one time-based and one frequency-based. If the resulting audio sounds distorted then try the other algorithm.

Step 4: Click “Convert now” and wait a minute, then press “click here” to download your audio files.

Part 3. How to Change Speed On Mac

If you’re a Mac user, we recommend using QuickTime Player, which is a built-in Mac music speed changer, enabling you to slow down or speed up audio very quickly. To adjust the speed, you need to open the Audio-Video Control panel, and if you hold the "Option" button down while mouse-clicking, you can increase the Forward or Reverse speeds in increments of 0.1x with speeds in the range of 1.0x through 1.9x having audio. The detailed steps are as follows.

Step 1: Download and open QuickTime player on your computer.

Step 2: Add the audio to the interface.

Step 3: Open the ”Window” menu and select the Show A/V Controls option. A dialog box will pop up.

Step 4: Adjust the playback speed from 1x to 3x.

Step 5: Close the dialog box and play the audio.
