Nobody expects studio quality recording from a smartphone, but the technology in HTC's recently launched One at least allows distortion free audio to be nabbed in the quietest or loudest environments, according to the company's blog. Describing BoomSound tech, HTC says the system brings two dual-membrane MEMS microphones to the handset, one of which is focused on sensitivity and the other on high decibel sources. The two signals are then combined electronically, resulting in whisper-level tones that are free of hiss along with concert level blasting that won't clip or distort. By HTC's reckoning, that means the audio that goes along with those UltraPixels will be clear whether you're capturing a physics lecture or death metal concert.
