Note: the music track is longer and very loud (play it and see for yourself)

The 'plan', for this part of the tutorial, is to move the recorded track to the centre of the music, have the music fade-in and fade out and to adjust the volume so the audio can be heard.

Step 1: moving the recorded track...

  • Using the Time Shift Tool, as in Options 1 and 2 move the recorded track to approximately the centre of the music track. It should look something like this...

Step 2: Fade in the intro music...

  • Using your Basic Editing and 'Trimming' Skills, select the music track, using the Selection Tool, Image of Selection Tool being selected from the start to where the audio begins...

  • Using the Effect menu select Fade In...

    Notice the change in the wave shape, starting small and getting larger.
Step 3: Fade out the end music...
  • Select the music track again, using the Selection Tool, Image of Selection Tool being selected This time from the end of the audio to the end of the music...

  • Using the Effect menu select Fade Out...

    Notice the change in the wave shape, starting large and getting smaller...

The resulting wave will now look something like this...

Step 4: Adjust track levels...

  • At the beginning of each track you can adjust the Gain: (Volume) In the example below the recorded track is changed to a gain of +9 dB
    Recorded track adjusted to a gain of plus 9 dB
    This makes it 9 decibels louder.
  • The music track in turn can also be adjusted; in the example the music track is changed to a gain of -15 dB
    Image of music track gain being adjusted
    This make it 15 decibels quieter.

Note: this doesn't alter the tracks it only adjust the volume at which they play relative to each other.

The resulting track will now sound something like this...
