Audio distortion isuue while playing on iphone speaker

[technace2015]

Firstly Thank you for this wonderful library.

But during the development process i encounter one issue while playing same file on HeadPhones and iPhone speaker. In headphone it work fine for me but in iPhone speaker sound like missing some instrument sound.

Here is dropbox URL of my existing code with audio file in which i can't hear guitar sound after 6 second only on iPhone speaker.

Did you ever figure this out? In my case, the audio sounds fine on the iPhone speaker but is distorted and high-pitched when I plug in my headphones.
