SYSTEM AND METHOD OF SMART AUDIO LOGGING FOR MOBILE DEVICES

摘要

PROBLEM TO BE SOLVED: To automatically start and end the recording of an audio signal captured by at least one microphone.SOLUTION: The mobile device is capable of adjusting a number of parameters related with audio logging on the basis of the context information of an audio input signal, and performs smart start 115 or smart end 150 of audio logging by automatically detecting a start event indicator or an end event indicator. These indicators may be based on the context information derived from: an audio signal; databases located within the mobile device or connected to the mobile device through wired or wireless network connections; non-acoustic sensors; or even a signaling from other smart audio logging devices.SELECTED DRAWING: Figure 1A
