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.
