For the first time ever, owners of iOS devices can produce videos with a high-quality 3D audio track just by wearing a headset. To achieve that, the microphones are positioned to pick up the sound just like your ears would. With the Smart Slider you can adjust the mic sensitivity to normal or loud, i.e. concert, environments. This results in a stunningly three-dimensional and immersive sound experience, which can be enjoyed with any headphones on any stereo-capable device, allowing the listener to experience audio as if they were actually there.
