Audio Speed Changer

Modify the frequency or tempo of your sound files by simply moving two sliders. If you move the speed slider, your music will play in slow motion or faster. On the other hand, if you move the pitch slider, you will get a high-pitched or low-pitched audio. Apply funny effects on your voice recordings. By playing with the sliders, you can get a squirrel or evil voice. In addition, some basic editions such as trimming or fading operations can be achieved. This app uses Superpowered for time stretching and pitch shifting.
