Latest Patents
Ali L Jalali holds a patent for an "Audio processing system for point-to-point and multipoint." This system includes a microphone, receiver, and a comb filter and frequency scaler at each station, designed to reduce acoustic echo and enhance the margin of acoustic stability. The system's architecture allows for cooperation between the comb filters and frequency scalers, which induces a frequency shift corresponding to the transfer function of the comb filters. Additionally, the system may incorporate auxiliary echo suppressors to further mitigate acoustic echo and improve stability in various transmission delay scenarios. This innovative approach ensures that the equipment used at each station is substantially the same, eliminating the need for equipment negotiation prior to conferencing sessions.
