-To edit effects, you can move the timeline cursor over the effect borders until it changes to a resize left or resize right icon. In this state, if you drag the end of the effect, it performs an edit just like dragging an edit edge. The five editing behaviors of track trimming \index{trimming} apply to effect trimming and they are bound to the mouse buttons that you set in interface preferences as shown in the previous screencast. \textit{Trimming} simply means changes the duration dragging the edges.

In this state, if you drag the end of the effect, it performs an edit just like dragging an edit edge. The five editing behaviors of track trimming \index{trim} apply to effect trimming and they are bound to the mouse buttons that you set in interface preferences as shown in the previous screencast. \textit{Trimming} simply means changes the duration dragging the edges.
When you perform a trim edit on an effect, the effect boundary is moved by dragging it. Unlike track editing, the effect has no source length. You can extend the end of an effect as much as you want. Also unlike track editing, the starting position of the drag operation does not bind the edit decision to media. The media the effect is bound to does not follow effect edits. Other effects, however, do follow editing decisions made on an effect. You can disable effects from being subject to the edit decisions by using the pulldown \textit{Settings} and toggling off Edit effects. If you drag the end of an effect which is lined up to effects on other tracks, the effects on the other tracks will be edited while the media stays the same. When you drag an effect in from the Resources window you can insert the effect in the portion of the row unoccupied by the trimming operation. In some cases you will want a trimming operation to change only one row of effects. This can be achieved by first positioning the insertion point on the start or end of the effect. Then press the shift key while beginning the trimming operation. This causes the operation to change only one row of effects.

-Noise removal from audio using FFT editing. Set the Denoise Power dial in dB and choose the number of reference samples.
+Audio sampling (time data) is converted to a frequency spectrum using FFT (\textit{Fast Fourier Transform}). Since the \textit{Signal} contains only the background noise while the rest of the clip contains noise + audio to clean up, you get separate frequencies so you can subtract them to get the clean audio only. Set the Denoise Power dial in dB and choose the number of reference samples.
+
+For example, if you record a voice with a microphone\protect\footnote{credit fary54}:
+\begin{enumerate}
+ \item You record 15 seconds of background noise (without talking). This is the \textit{Signal audio clip}.
+ \item After 15 seconds, start the voice. This is the whole \textit{Noise Audio clip}
+ \item You stop recording.
+ \item You place the FFT effect on the whole length of the recording (including the 15 seconds of signal noise).
+ \item Then place your cursor at the beginning of the 15 seconds. Enter the number of samples in the effect presets, e.g. 65536.
+\end{enumerate}
+
+This has the effect of creating a keyframe that marks the beginning of the reference range which, in our example, ends at 65536 samples later.
+
+During playback, the background noise is then automatically removed along the entire length of the effect.
