Changes

Audacity has tools to fade in and out. When you "fade in," it means to gradually increase the volume level from silence to the original level. When you "fade out," it means to gradually decreased the volume level from the original level to silence. Professional recordings of concerts often fade out after a song, while the audience applauds. Fading out avoids an abrupt stop at the end of the recording, because the volume level is decreased gradually to silence.
