Adding a Block

We’ll be making a nighttime soundscape. You’ve already opened the files you’ll need to create this.
Let’s start our soundscape with something solid and predictable, an existing ambient sound; this will be our anchor or through line on which we’ll add unique character.

• First, click on the title “Track 1” and rename it to be “Ambience”
  
• Drag the file NightAmbience.wav from the files section to the Ambience track
  
• A block will appear with the label, “NightAmbience”. You can move the block to the left and to the right, adjusting it in time. You can also move it up and down, changing the track it’s assigned to. Here, we want to move it all the way to the left (time stamp 0:00) and want it to stay in Track 1, “Ambience”.
• This night ambience wants to last twice as long. To do this, we first want to select our ambience block (if it isn’t already) by clicking anywhere on the block. You’ll notice the color and outline change. Click anywhere in the gray, where no blocks exist, to deselect the block – or – Edit > Select > Deselect All. 
  
• Next copy [Ctrl + C] it and ensure that the Ambience track is still selected
  (the paste command will paste the block into whichever track is selected).
  Then place your playhead somewhere after the first block and paste [Ctrl + V]
  Or if you would rather, you can drag the block while holding down the [Alt / Option] key to duplicate the block.
  
• Now we want the two sounds to overlap. Let’s start by trimming the excess silence from the block. This can easily be done by placing your cursor at the end of the block. Your mouse will turn into a red bracket. Drag the end of the block until the silence is gone.
  
• Now that your block is trimmed, we can be ensured that an overlap will have a clean crossfade. To do this, simply drag your block on the right on top of the block on the left.
  Create a good 10 second overlap. You’ll see that there are yellow envelop lines, similar to the Waveform view.
  
• These can be adjusted further by grabbing and moving the envelope handles.
  

Listen to the transition between the two and notice how seamless they are. Move the blocks around if you need any adjustments.
