Please add an option in the player to adapt the music in realtime from 440hz (the common) to 432hz (natural and organic sound). In intenet you can found so much info, here is a link with info related: http://www.roelhollander.eu/en/432-tuning Some music players: http://www.roelhollander.eu/en/432-tuning/432-music-players/ The audio really feels more natural. The people is converting his tracks on a PC from 440hz to 432 and posting on youtube. A real innovation it's to change the frecuency to 432hz (with accuracy) in real time (with the quality of Poweramp) (You can do it with "432 player" app on iphone.) Thanks a lot! I recommend Poweramp to all the people for be the best music player on android.... please add a posibilitty to change the freq. thanks for answer... Regards from Chile!
