I need to find an audio player app that can change the playback speed (slower and faster). Does anyone know an app that can do this?
VLC allows you to change the speed of reproduction from 0.5x to 2x, as you can see in this image:
Audiobooked is an app designed for audio-books, with speed control, bookmarks and more.
Unotune player allows a changeable audio playback rate while preserving the pitch.
