The Nokia Lumia 920 features 3 High Amplitude Microphones: Confirmed by Nokia data sheets
Forget about having dual microphones. Slashgear has been able to confirm that the Nokia Lumia 920 sports 3 special High Amplitude Audio Capture microphones, just like the Nokia 808 Pureview, which allows it to capture very soft and very loud audio while making video recordings which are much closer in fidelity to human hearing, perfect to record that rock concert while also recording the low-light video stream in 1080p.
HAAC is explained below:
â€œTo cope with high sound pressure levels, Nokia has developed together with microphone suppliers a new microphone concept (High Amplitude Audio Capture) that can capture high sound pressure levels with perceptually no distortion to the audio. It is capable of recording up to 140 dB and higher Sound Pressure Levels, while that commonly used digital microphones can only reach 120 dBSPL without heavy distortion. As high amplitude audio levels are tolerated, there is no need to limit the frequency response. Hence full audio bandwidth to match to human hearing capabilities can be provided when capturing with HAAC microphonesâ€
The Nokia Lumia 920 continues to deliver in terms of technology, making it for once a Windows Phone that can measure up feature to feature with the best of Samsung and Apple.
