Some puzzles in The Witness are sound based. So you need to distinguish high and low pitch sounds, and this is just headache for me. Literally.
Thereby, I would like to someone else to do this painfull job for me, but only this part: Imagine that you have a person with big hearing problems and you need to reformulate those puzzles for them, using music notation, or text description, or pictures, things like this. Please do it with minimum amount of spoilers to the puzzles themselves.
As a matter of fact, I was able to solve puzzles, which one needs for a laser) by trial and error and what I need right now is to understand sounds from the additional (vault) puzzle.
But still, I think it would be nice to have a complete answer, which includes decoding of all sounds in the puzzles.
Best Answer
I think the most spoiler-free reformulation naturally would be spectrograms of the sound records. Since, they allow you to hear with your eyes.
I made them and checked that you can see (on spectrograms) all the patterns, which I was able (hardly) to hear (in the sounds), that means the puzzles must be solvable with my spectrograms even if you hear nothing.
Note:
1. Many puzzles becaume trivial for me once I saw the spectrograms, but some still are hard (see note#2 below). I think this is perfectly normal, since exactly the same was true in the other parts of iland: most of the puzzles where just to make sure that you understood rules correctly, not to be a challenge. Also I think this was the case for a musician, who would hear sounds.
2. Even once you figure out all the rules correctly you still may need some trial and error to make sure if you see correctly, but these are minor (much much smaller than I had to try using my ears).
3. On the spectrograms below you will see time on horisontal axis, frequency on the vertical and the color shows intensity of the sound component.
