Acoustic weighting filters

When you press the Setup button or open a new math Acoustic weighting filter, the following setup window will open:

Weighing filter_Setup

Weighing curve selection

To add a weighting curve select the required filter. The filter will be applied to the selected Input channels.

Weighing filter_Curve selection

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.
