Then, click YYEESS to store your measurements (Figure 5.23).
If you choose to continue with more measurements, select YES
and follow ERGO’s prompts. Some rooms take many
measurements; some can reach this level with only 3
measurements. ERGO will not let you store a room correction
until Room Knowledge is at least 90%. You may continue taking
additional measurements to increase Room Knowledge, which
will result in a more accurate correction filter.
So, what did ERGO just measure?

Room Knowledge indicates how much information has been
gathered about the room. In normal rooms, a listening position
measurement and a minimum of 34 additional measurements
are adequate to get a Room Knowledge of 90% or better
regarding the room’s acoustic properties. Once Room
Knowledge reaches this range, ERGO can begin processing the
room. Additional measurements can improve Room Knowledge,
up to 100%. With ERGO Cal, measurements are analyzed in
real-time.

Knowledge about the room is calculated and if the measurement
positions have not gathered enough information, you can take
further measurements until there is enough information present
for a proper analysis. (Figure 5.24)
When sufficient Room Knowledge has been obtained, target
curves, focus filters (listening position) and global filters (general
room filter) are generated automatically and stored in ERGO.
...and you’re done with room calibration.
The following screen will appear and prompt you to release the
Calibrate button – go ahead and do it. (Figure 5.25)
