The fade-out feature of Trebble β similar to the Fade-in β allows your background audio or music to gradually fade out at the end β and this starts at the number of seconds you select on the background audio settings pane. This means that the volume of the background audio or music you add to your audio recording starts decreasing until it fades out completely.
To fade out music, add your background music to your preferred portion of the audio recording and do the following:
Step 1: Click on the music icon at the beginning or end of your background music to see the background music settings panel by the right.
Step 2: Use the scroll bar on the background music settings panel to scroll down to the Outro section. You should see the Fade option under it. You can then adjust by dragging the bar to your preferred number of seconds.
Step 3: To test your fade, click on the music icon at the start of the highlighted text. The Play from here and Delete buttons will appear around the music icon. Press the Play from here button to test the intro music you applied.
