  1. Hi,
    i have a big worry with video recordings Gigs(techno music) at high volumes the left way encounters awful distortion.
    even no sound, perhaps my worry is due to the noise cancellation mic related to left way?
    Also i have no “noise cancellation” option to tick or untick
    And does it mean top microphone , is not at all used for stereo recordings in videos??
    i opened a thread in xda-developpers “BAD Audio when Video Recording in GiGs (techno music)”
