Choose Yes to save the performed room measurement and No to exit without saving any
of the performed measurements.
Adding one or more room measurements leads to a re-calculation of all filters (i.e. Global
and all Focus filters) due to the fact that more of room’s acoustic properties have been
learned, something that affects all filters.
d. RoomKnowledge Index
Here the current RoomKnowledge index is displayed
Press enter to check the RoomKnowledge index.
The RoomKnowledge index is a parameter that tells how much of the room’s acoustical
properties have been learned. A high RoomKnowledge ( ≥ 90%) means that most of the
room’s acoustical properties have been learned. The more room measurements you add,
the higher the RoomKnowledge will become. The more that the acoustical properties of
the room are learned, the greater the accuracy of the room correction.
e. RoomCorrection Index
Here the RoomCorrection index for each filter can be viewed.
Press enter to check the RoomCorrection index.
The RoomCorrection index is a measure of how much processing is being employed in the
room correction filters. To some extent the RoomCorrection index reflects how audible the
correction is. However, the same amount of processing can sound very different due to
