Latest Patents

Frauenthal holds a patent for "Echo mitigation in the presence of variable delays due to adaptive jitter buffers." This patent introduces a control connection between an adaptive jitter buffer (AJB) and an adaptive bulk delay (ABD) buffer within an echo canceller (ECAN). The control connection enables the AJB to manage the delay inserted by the ABD, ensuring that the internal echo estimate remains time-aligned despite variations caused by network-induced delays. This advancement preserves time-invariance in the echo tail path, enhancing the quality of audio in IP communications.
