A common problem in acoustical echo cancellation is the continuous change in the room 's impulse response. These changes need to be monitored and adapted to in order to create an enjoyable echo-free environment. In the experiment proceeding, measurements were taken to find an optimal FIR filter that would allow for fast convergence of the adaptive filter as well as a significant echo return loss. Finally, considerations were also taken to create a smooth adaptation from one configuration to the next.
