I just read that media players can alter the subliminal file's frequency, so which player i can use in a android cell phone ?? i am currebtly using poweramp with all mods( equalizer, bass boost, treble etc ) disabled.
i use JBL 150a noise cancellation earphones.
I think I've read somewhere that (active?) noise canceling phones are no bueno.
Following the thread; using PowerAmp myself.
I use one of the default players on my Galaxy S4. It has no apparent name, but has an icon showing a blue circle with a blue "play" triangle with a green flagged note over it.
I don't know which players on an android phone or apple phone would affect the frequency if any. I know mine does not.
