If you want the same features as Rockbox on an Android app then you are probably out of luck. Last time I checked Rockbox was still the most versatile audio player around. I love some of its advanced bookmarking, scripting and voice control features.

VLC does seem to have independent pitch and speed control (see https://www.reddit.com/r/linux/comme...peed_controls/) but I am pretty sure you will not have the same experience if you have been used to Rockbox.

Some Chinese guys patched Rockbox and seemed to work on newer versions of Android. https://github.com/Rockbox-Chinese-C...ty/Rockbox-RCC
