7. Final remarks


Once you have designed your ideal crossover frequency and target curves for each group, press "Calculate" in the lower right corner. The bass control filters will now be calculated.
After the Bass Control calculation is done, select the "Corrected" checkbox in the plot options to show the resulting input magnitude response for the selected channel. The corrected curve should conform to the target curve, as illustrated below.
Click "Proceed to Filter Export."

Filter export

The last step of the process is exporting the filter generated by Dirac Live® 3 for a live listening test. Select a slot and save under the desired name (there may be an auto-generated name, which can be replaced). When the export is complete, the application will return to the Filter Design view. Do not forget to save your project before closing the application.
