Figure 18. Optimize System Screen
The resulting system responses are shown in the lower panel on the Optimize screen. These are
validation models computed by applying the filter to the system measurements.
If the target response is not reached everywhere, it may be due to a filter gain limitation. To
protect speakers from excessive boosts, there is a frequency-dependent gain limit on the filters.
The target response can be adjusted after an optimization has been carried out by repeating the
steps above (see Edit Target, page 15). If the target response is changed after an optimization has
been done, the previous filter is discarded. By clicking Optimize again, a new filter is computed.
Only the magnitude response correction has to be recalculated; the impulse response correction
remains the same regardless of the target response. The time to compute a new filter is therefore
reduced after the first optimization has been carried out.
2.5. Export the optimization
1. When satisfied with the Dirac Live
®
optimization, press the Export button. Then click
Download to download filters, delays, and gains to the amplifier (the AP20). See Figure
19. A dialog box will appear in which you need to enter a file name for the set of
configuration filters, then download it to the AP20.
Note: The dialog box may appear behind the application window in the program. You
must find the dialog window to continue the download process.
Select Impulse response to view the average
impulse response before and after optimization.
