Classification: CPC G | IPC G

Claim 12:
13. A system comprising:
at least one processor; and
memory including instructions operable to be executed by the at least one processor to cause the system to:
receive first data, the first data corresponding to a first time interval and a second time interval after the first time interval;
generate, using the first data, second data corresponding to a first audio source, wherein the first audio source is represented in a first portion of the first data;
generate, using the first data, third data corresponding to a second audio source, wherein the second audio source is represented in a second portion of the first data;
determine that a third portion of the first data comprises a representation of a first event, the third portion of the first data corresponding to the second time interval;
determine a first power value corresponding to a fourth portion of the first data, the fourth portion of the first data corresponding to the first time interval;
determine, based on the first power value, that noisy conditions are present in an environment of the device;
determine first weight values corresponding to two or more input features in response to determining that noisy conditions are present in the environment of the device;
determine, based on the first weight values and the two or more input features, a first value that represents a first likelihood that the first sound source corresponds to the first event;
determine that the first value satisfies a first threshold; and
associate the first event with the first audio source in response to determining that the first value satisfies the first threshold.
