Accurate mode/Fast mode
The adaptive filter can be switched between a Fast filter mode and an Accurate filter mode. In the Fast filter mode
the system converges faster. As a consequence, this mode is suitable for situations where the microphone position
changes over time, e.g. in case of a handheld microphone or in a discussion system with multiple switching
microphones.
The Accurate filter mode is for situations with a fixed microphone position, e.g. on a pulpit. Then the acoustical
environment is more stable and the adaptive filter is allowed to converge more slowly to suppress the reverb
components even more.
