Short answer: Load the audio, select a range, enable Fade In or Fade Out, enter the duration, and preview the selection. After adding segments, each item can keep a different fade configuration.
What each fade fixes
A fade in raises the level gradually from silence, preventing an abrupt opening. A fade out lowers the ending smoothly to silence. Fades are common in ringtones, short-video music, podcast endings, and song excerpts without a natural ending.
Starting-point durations
- Prevent an edit click: use a very short fade so speech or transients remain intact.
- Speech: about 0.1–0.5 seconds often sounds natural.
- Ringtones and short music: a 1–2 second ending fade is a useful starting point.
- Ambience: use a slower fade when the source and clip length allow it.
Different settings for each segment
- Use the main fade controls as defaults for a new segment.
- Add the selected range to the segment list.
- Under that item, enable either fade and adjust its own duration.
- Preview the merged sequence before exporting.
A fade is not a crossfade
A fade changes the level near one segment boundary. A crossfade overlaps two segments in time while one falls and the other rises. The tool currently provides independent fades per segment; it smooths abrupt boundaries but does not overlap two clips.
