Fill missing 8 kHz value of absorption coefficients

Selecting this command opens a dialog offering to extend a possibly missing absorption coefficient to the 8 kHz octave. By answering „Yes“, the value of the 4 kHz octave is copied to the 8 kHz octave for all local absorption coefficient spectra. At the same time, the string variable „8K_INTERPOL = 2“ is set (in the memo-window of each absorption coefficient spectrum).

Holding the SHIFT key while selecting this command, the extrapolated values in the 8 kHz octave are deleted and the string variable in the memo-window is removed (after confirming a prompt with „Yes“).

In both cases, the number of changes is displayed after the action has been performed.
