Claim 12:
13. A device for generating a database, comprising:
a microphone for continuously receiving environmental noises;
a buffer for deriving a set of parameters from the environmental noises and for continuously buffering the set of parameters for the migrating time window in order to acquire a continuously buffered recording;
an interface for acquiring a signal subsequent to the migrating time window, the signal identifies a signal class of a plurality of signal classes in the environmental noise; and
a memory for storing the continuously buffered recording corresponding to the migrating time window in response to the signal so as to extract a portion of the buffered recording associated with the migrating time window out of the continuously buffered recording, wherein the signal is received by a user input device, a button or a smart device; wherein the buffered recording is deleted without storing when the signal is not acquired, wherein the signal generated in response to a human input;
wherein the device is configured to repeat acquiring and storing in order to acquire the database which comprises a plurality of buffered recordings for the same signal class;
wherein there is a temporal dependence between the signal and the migrating time window of the buffered recording; wherein the temporal dependence is that the beginning of the migrating time window is before the time of the signal; and wherein the end of the migrating window is at or before the time of the signal.
