Audio editing in energyXT

energyXT comes with audio editing built-in to each audio track. This tutorial will show you how to get started with the most used features. For advanced editing, you may also open recorded audio in an external audio editor directly from energyXT. 

Trimming audio

You can trim the start and end points of your recording. Click the start or end point of the audio and drag to the desired position. 

By default all editing will snap to the nearest beat, but you can change the resolution or turn off snapping in the toolbar. 

Splitting audio takes

There are several ways to split an audio file. You can press the alt button and right-click anywhere on the audio file or you can set the song position pointer and select Split from the Part menu (the shortcut is Ctrl + K). Make sure to select the part you want to split. 

You can now edit, move and copy the two audio files separately. 


If your audio recording has unwanted clicks/pops at the beginning or end you may select to fade in or fade out the volume with a specified number of ms. Open the object-bar to access the fade in and out option. 

You may also cross-fade two audio files by overlapping them, select both and right-click for popup menu, and finally select Crossfade from the Process menu. 

Reversing playback

In the object-bar you may also select if the audio file is played back in forward or reverse mode. 

Render mode

For more advanced playback option you may specify the render mode for each audio file. Select between Normal, Re-pitch and Stretch. 

In Normal mode the audio will always be played back at the same speed/frequency as recorded.  

In Re-pitch mode the sample will play faster or slower depending on the current tempo. Changing the tempo will also change the frequency of the audio file. If you don't want this effect set the audio file in Stretch mode. This option will automatically stretch and pitch the audio to the current tempo. 

In Normal and Stretch mode you have also Coarse and Fine tuning control over the audio file. 

Setting the track in edit mode

For more detailed audio  editing you need to set the track in edit-mode. Double-click or right-click the track and select edit from the popup menu.

You will now see a bigger view of the recorded (or imported) audio file. 

Editing only a selection of the audio file

To make a selection simply click and drag with the mouse on the waveform. By default snapping is used here as well. All editing is now done on the selection only. 


Once you have made a selection you may perform standard editing like cut, copy and paste with the shortcuts Ctrl + X, Ctrl + C and Ctrl + V. 

The Process menu

On the process menu you will find more editing option. Right-click the audio file and select Process. 

If you want to apply editing to the whole audio file, remove the selection by a a single click on the audio file. 

Normalize selection

To normalize the audio file, simply select Normalize from the Process menu.

Using external audio editor

If you have a favourite audio editor you may even use this to edit the audio file directly from energyXT. Just select the audio file, right-click to open the popup menu and select "Open with..." from the Process menu (shortcut: Ctrl + Shift + E)
