Question 2

To make proper use of panning I looked at the rest of the tracks. These were the instruments that I didn't want to be still in terms of space. I not only wanted them to move from left to right in the perception of the listener, but I wanted them to move from front to back.

These tracks included four separate vocal takes that were exclusive to the last 2 choruses and the bridge, the stereo organ track, and two separate lead guitar tracks. All of these individually were mono tracks, but they all had stereo outputs (as all tracks do in Ardour.

To make these tracks MOVE in space, I used the panning function in Ardour. This works by panning the track between the two outputs that you have designated - basically in stereo. Thus, to move a track in space via surround sound you need to pick the two speakers (or another way to think of it is the two locations in space) for each track that you want to move to and from. The surround sound space has 2 dimensions: front to back, and left to right. Each mono track can move in 1 dimension at a time. Thus, for each instrument you either need to double the track (which I did on one of the guitar lines), or have each track in stereo, which I was able to do for each vocal line and the organs. Thus you can have one track function as the front to back dimension, and the other can function as the left to right dimension. Just fiddle with the panning and gain automation, and you have some great surround sound effects.


That image shows the panning during the 2nd chorus of the song. There is a short lead guitar line that I attempted to move from the front-left of the listener to the back-right. As you can see, there are two tracks "E Guitar 2 L", and "E Guitar 2 R". "2 L" is connected to speakers 7 and 8, and is panned to go from speaker 7 (back left), to speaker 8 (back right). "2 R" is connected to speakers 1 and 2, and is panned to go in the same direction - speaker 1 (front left), to speaker 2 (front right). Where we get the 2nd dimension of depth is from the 2nd fader - the one that controls the gain. Track "2 L"'s gain is matched with its panning, so it starts off quiet and gets louder as the panning moves to the right. The opposite is true with Track "2 R". It starts off loud and gets quiet as the panning moves from left to right. Thus, the overall effect has this guitar riff going from the front left to the back right of the listener.

The organ and vocal parts are a bit less complicated. They simply move from front to back, or from back to front throughout the duration of the song. You can hear the organ move towards the back (with the rest of the static high end parts) when the lead vocals kick in during the first verse. Other parts are more subtle, but they are there. The vocal lines move much more violently forwards and backwards during the 2nd half of the song, beginning at the 2nd chorus. I did this to create the surround sound version of a chorus effect, as we have up to 5 voices singing at certain points.
