Depending on how the track is displayed and what spectral selection has been made, this effect will do one of the following:
 * When the track is not in spectrogram or spectrogram log(f) view an error message will be displayed
 * When the spectral selection has a center, upper and lower frequency this effect performs as a notch filter with the center frequency defined by the center frequency of the spectral selection and the width defined by the upper and lower frequencies of the spectral selection
 * When the spectral selection begins at 0 Hz this effect performs a high pass filter with a rolloff of 12 dB/octave and with the cutoff frequency defined by the upper frequency of the spectral selection
 * When the spectral selection ends at the Nyquist frequency of the track this effect performs a low pass filter with a rolloff of 12 dB/octave and with the cutoff frequency defined by the lower frequency of the spectral selection
 * When the spectral selection begins at zero Hz and ends at the Nyquist frequency the error message "Please select frequencies" will be displayed.

Notch Filter
If you make a spectral selection that has both an upper and lower boundary, selecting will apply a notch filter.

In the following example the spectral selection had a center frequency of 2000 Hz and a bandwidth of 0.5 octave.

In the following example the spectral selection had a center frequency of 2000 Hz and a bandwidth of 2 octaves.

High-pass filter
If you make a spectral selection that has the lower boundary at 0 Hz, selecting will apply a high-pass filter. In the following example the spectral selection had a lower boundary of 0 Hz and an upper boundary of 500 Hz.

Low-pass filter
If you make a spectral selection that has the upper boundary at the Nyquist frequency of the track, selecting will apply a low-pass filter. In the following example the spectral selection had a lower boundary of 0 Hz and an upper boundary of 2000 Hz.
