No this doesnt improve the sound!

People say this improves the sound... NO, no it does NOT! What you are hearing is either a bass, treble or gain boost or a virtual 3d. Since ALL of those things could have been done by the recording artist you just have to wonder why didnt they do it? Even Dolby surround can permanently be recorded but never is for a good reason.

That said Dolby Surround is the only good idea and it falls short... Dolby surround will only hurt the sound unless the source is surround and since this app wont play movies its just worthless! Even if it did work Dolby surround does cause a reduction in sound quality and sometimes sound artifacts. This is something you can deal with as in return you really do get the surround sound experience although not as good as real surround and never quite capable of making something sound like its coming from a front or rear center channel but its great at front left front right rear right rear left kind of sounds.

Anyways the app is worthless
