You have asked about the filters’ cut-off frequency. If you are using the filters for each user, you must as well consider the bit rate of each user in this case. The “bit rate” mentioned in the script of the filter is also the one that is determined in the global parameters. So setting the value of every parameter which might be used in many components in the global parameters and using the script mode for them can sometimes be really time saving, so you would just change it in the global parameters and its value changes for all of the components.
