mamue started following works great on ZTE blade v6, timestretching knob a bit too vague
I used Poweramp for a year or two as my main audio player during dancing lessons but was missing timestretching, which is now included. Great! Absolutely great! It is a bit difficult for me though to change the speed in fine steps; i tend to use it within a range of +/-15% at maximimum. Changing speed to e.g. +2.5% seems not possible, at least not for me.
