Yes, you can remove a portion in the middle of a song or soundtrack by adding the same audio file to the timeline multiple times and trimming each instance of the audio file from the left or right end as needed.
For example, you can add a song, then trim from the right to preserve the desired beginning portion. Add the song again and trim from the left to preserve the desired end portion. Then, align the trimmed segments to create the edited version of the song.
