Generate filter kernel

Select measurements

Select at least one measurement as template for the filter kernel. It is a good advise to use multiple measurements taken at different locations. You can select from all measurement files in the working directory.

If you want to optimize the result for a certain listening position in the room then select multiple measurements that are taken close to this position.

If you prefer to get a compromise that does not sound ugly when you move around in the room then take measurements from entirely different locations. DRC123 will take back the level at resonant frequencies in doubt to avoid resonances. If a certain region is your preferred listening place then select more measurements from this area.

Generate the filter

1. Press the Generate button and wait for the operation to complete. This usually takes only a few seconds.
   You will see the result in the embedded graphs. Note that the filter is the inverse response, i.e. high gain values are low gain in your room response and vice versa.
2. Enter a file name. Because of the asynchronous processing you can do this while the calculation of step 1 is still running.
3. Enter a descriptive text. This will help you to select the right filter in playback mode.
4. Save the result.

If you are experienced or you just want to play around with the settings also have a look at the filter generation options.

View result

There are three view modes. The default is to show only the result. The boundary bars show the minimum and the maximum of the contributing measurements.

The other two modes show either the gain response of the group delay of all contributing measurements (at most 11). This can be used to compare measurements. Note that you always need to generate the filter when you have selected other measurements.
