ABSTRACT:
Systems and methods for noise cancellation are provided. In particular, information regarding events associated with a computer providing a telephony function or associated with a hardware telephone providing a telephony function is provided to a noise cancellation process. The provided information can be used to identify specific noises associated with events, so that filters specifically adapted for removing an identified noise can be applied. Alternatively or in addition, information regarding the existence and timing of an event can be provided in order to facilitate the application of a noise cancellation filter. Noise cancellation as described can also be applied in connection with recording speech or other audio signals.
