So how does it work? Well, let’s say you have a movie theater with speakers placed all around the room. To make things easier for us, let’s assume there are only four speakers: one at the front left corner (FL), one at the front right corner (FR), one behind your head (C), and one on the ceiling (LFE).
Now imagine you have a sound wave that needs to be played through these speakers. This is where our matrix comes in handy! We can create a 4×1 matrix, which looks like this:
[ FL | FR | C | LFE ]
This matrix represents the volume level of each speaker for a specific sound wave. For example, if we want to play a loud explosion from the front left corner (FL), we might set its value in the first column to 100 and all other values to zero:
[ 100 | 0 | 0 | 0 ]
But what about when we have multiple sound waves playing at once? That’s where our matrix calculations come into play. We can create a larger matrix that represents the volume levels for each speaker and each sound wave:
[ FL1 | FR1 | C1 | LFE1 | FL2 | FR2 | C2 | LFE2 ]
This matrix has 8 columns (4 speakers x 2 sound waves) and 4 rows (one row per speaker). By manipulating this matrix using basic math operations like addition, subtraction, multiplication, and division, we can create a more immersive listening experience for the audience.
For example, let’s say we want to increase the volume of the explosion sound wave coming from the front right corner (FR) by 50%. We could do this by multiplying that column in our matrix by 1.5:
[ FL1 | FR1 * 1.5 | C1 | LFE1 | FL2 | FR2 | C2 | LFE2 ]
Or let’s say we want to decrease the volume of all sound waves coming from the ceiling (LFE) by 75%. We could do this by multiplying that column in our matrix by 0.25:
[ FL1 | FR1 | C1 | LFE1 * 0.25 | FL2 | FR2 | C2 | LFE2 ]
By using these simple math operations, we can create a more immersive listening experience for the audience and make them feel like they’re right in the middle of the action!
