Then, click YES to store your measurements (Figure 5.23).
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)
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?
5.2.6Room Knowledge
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
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)
