The fade-in feature of Trebble allows your background audio or music to start from the lowest volume and increase to the highest volume you set on the background music settings panel. This means that the background audio or music you add to your audio starts from the lowest volume and increases.

To fade in music, add your background music to your preferred portion of the transcription file and take the below steps:

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 Intro 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 and Delete buttons should appear around the music icon. Press the Play button to test the intro music you applied.
