FFT Filter

The FFT (Fast Fourier Transform) Filter allows to reduce or increase the intensity of the frequency in accordance with the selected frequency profile. The filter smoothes the signal during a time in limits of the FFT block. It is recommended to use the filter in the following cases: for the extreme filtering - when the processing result as a fact is more important then the possible smoothing effect; for the cutting of the specified frequencies. If you select a part of the file with the mouse, this effect will be applied to this exact part of the file. Otherwise the sound of the whole file will be affected.

To apply the effect you should do the following:

1. Add the audio file to the Waveform Editing Space.
2. Select a part of the file you would like to apply the effect to or leave it unselected to apply the effect to the whole file.
3. Click the FFT Filter button on the Effects Tab or double-click the FFT Filter on the Files and Effects Panel.

4. Adjust the effect parameters or select one of the available presets from the list.
   Note: if you change the effect settings, you can save them as a preset to be able to use them afterwards. Use the Add button to do that.
5. Click the Preview button to make sure that the changes are correct.
6. Click the OK button to return to the audio file editing.
