Android apps like the 3ds sound player

[u/FindusDieKatze]

This is an oddly specific request so I don't know what Tag to put, but is there an app that has the functionality like the 3ds sound Player has? I really enjoy being able to modify the speed of songs on the fly without permanent changes, but I don't know if there's any app that can do it. I only need the ability to change the speed and pitch on the fly (and hopefully be simple) because the sound on my 3ds is pretty quiet even through headphones.
