Acoustic weighting filters
When you press the Setup button or open a new math Acoustic weighting filter, the following setup window will open:
Weighing curve selection
To add a weighting curve select the required filter. The filter will be applied to the selected Input channels.
The acoustic weighting will be perfomed on all the selected input channels.
Time domain filters are automatically used for non-complex input channels that have a synchronous time base, e.g. like the raw analog input channels or derived 1-to-1 sample channels.
Frequency domain filters are automatically used for array input channels having a frequency axis, e.g. like spectral channels from FFT or Octave analysis.
