Abstract: An exemplary system comprises a device including a memory with an audio injection application installed thereon. The application comprises an equalizer module that analyzes sound characteristics of individual digital audio samples including a discrete signal, a selector module that applies a selection heuristic to select the discrete signal from the individual digital audio samples based on the sound characteristics, and an audio module that supplies to an output an insert signal generated according to the discrete signal selected by the selection heuristic.

Abstract: Methods and systems for automatically providing conference calls are disclosed. In one aspect of the invention, methods and systems detect a conference call event that was previously configured by a subscriber user and identify participant users associated with the conference call event. Once identified, each participant user is contacted and a response is received from each of the users. Based on the received responses, a conference call is established between the participant users and the subscriber user. In one aspect of the invention, at least one of the detecting and identifying steps are performed without user intervention.
