I am using CrazyTalk 6 Pro. I have added duplicate audio tracks for 4 actors (Choir). After the end of the audios I hear a duplicate playing in the back ground at 1/4th volume. There are no audio sections showing for that time in the Timeline. Previous to this, I had done numerous additions and deletions of audio tracks to get the sounds I liked. Has anyone had this problem? What causes it? and does anyone have a fix?
