Abstract
Aspects of the subject technology provide for joint processing of signals from acoustic microphones and signals from vibration sensors that directly or remotely sense vibrations of the source of the sound itself. The vibration sensors may include remote vibration sensors such as a light-based microphone, which may be implemented as an optical microphone. Joint processing of the signals may include detecting a sound from the source in the signals from the acoustic microphone by selecting a portion of the signals from the acoustic microphone based on the signals from the vibration sensor.
