  • information regarding the treatment itself : temporal location, duration and options,

  • information about selected points in the BPF and displaying parameters.

Depending on the type of treatment, other information, as well as options, such as the time correction, or the preservation of the spectral envelope for a transposition... can be displayed.

To display information about the treatment click on the upper bar of the BPF editor.
