Claim 0:
1. A method for generating a database, comprising:
continuously receiving environmental noises and deriving a set of parameters from the environmental noises and continuously buffering the set of parameters for the migrating time window in order to acquire a continuously buffered recording;
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;
storing the continuously buffered recording corresponding to the migrating time window in a memory responsive 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;
deleting the buffered recording without storing when the signal is not acquired; and
repeating acquiring and storing in order to acquire the database which comprises a plurality of buffered recordings for the same signal class;
wherein the signal is received by a user input device, a button or a smart device;
wherein the signal is generated in response to a human input,
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.
