Yes you can! To control the speed of an audio blink tap the '1.00x' speed button underneath the play/pause button in audio mode and the audio will play faster. Repeat this step and the audio will play even faster! You have the speed options 1.00x, 1.25x and 1.50x (in Android up to 2.0x). To set the speed back down, just tap one more time.
