Behind all this innovation in speaker quality is a company called NXP semiconductor. The latest Motorolas use 1 NXP-controlled speaker while the HTC One uses two of them, and they are already showing the future of smartphone audio.
The new audio tech that they are developing will likely arrive for 2014’s early flagships and will introduce some slight, but noticeable improvements.
NXP is demonstrating what it will all sound like right now, so your ears can get a taste of it. The new chip TFA9895 audio chip will not rely on boosting voltage up - instead it will take care of delivering good sound at both maximum and minimum loudness.
To do this, it separately controls different frequency bands so when the vocals in a song get loud, there would be no need to quiet down other instruments as is currently the case. The difference will allegedly be noticed by the careful listener. A demonstration of the new technology follows right below.
