The Decorrelation audio panel allows to load the impulse responses (IRs) coefficients to be used for decorrelation processing for each channel. Use “Import” or “Import All” option to import the IRs. The panel will display channel wise graph for coefficients and filter length.
- Channels: Show all channels list, you can select channel to view its graph.
- Sample Rate: Show sample rate of current framework instance.
- Non-zero Taps: Show non-zero elements defined for decorrelation audio object.
- Graph: Show graph of coefficients and filter length.
- Import: Use to import selected channel coefficients file.
- Import All: Use to import all channels coefficients file.
- Send: Use to send non-zero coefficients to device.
Validation
It will validate coefficients file and ask confirmation for below error messages.
- The filter length does not match the number of coefficient rows in the CSV file.
- The number of non-zero elements does not match the number of coefficient rows in the CSV file.
- The CSV file contains more coefficient columns (for Import).
- The CSV file columns do not match the channels (for Import all).
If you click on “Yes”, then it will proceed for import else it will cancel it.
“Import” and “Import All” will update state variables and send non-zero coefficients to device if device online.
