the lesser static noise removal filters, the ones included to push a cheap sound design program as opposed to being the entire point of the program you put out a grand for, they typically work by taking a five second or less sample of the noise you are trying to clean out of the file--just the undesired noise itself. line hum, tape hiss, buzzing from the computer fan.
it creates a filter that will block those frequencies where the static noise exists: it does not eradicate the sound itself. after creating the filter, you apply it to the whole file and are left, presumably, with any sound not in those frequencies. except not every aspect of the static noise keeps the same frequencies throughout the whole file, and at times the blocked frequency coincides with the range of desirable sound. especially when cleaning a spoken word piece, you are left with a noise like crumpling tin. the rustling of metallic wings. charged wires loose inside of your mouth, small shocks clustered around every part of speech. corroding away at the simplicity of one person speaking in what they'd believed to be an otherwise silent room.
last night i experienced my first migraine aura. experienced, at least, in conscious awareness, as some of the sensations involved were very familiar, have been a part of my life since i was very young. my left eye was riddled with zigzags in half circles that distorted my vision, in spite of the fact that i could not actually see them. the edges of things came into focus with nearly obscene clarity. i didn't want anything to do with direct light. it felt, though it never appeared, that i was a half mile gone from everything in my immediate vicinity. i felt like a creature trapped outside of itself, void roaring in every direction.
ben recognized the structure of things, had me take two naproxen, had me take a decongestant, had me lie down and turned out the lights. we sorted out my chaotic panic points:
- is it a stroke?
- it's not a stroke.
- is it what nate had on six feet?
- it's not what nate had on six feet.
- ...is it eye strain?
- it might be eye strain.
i did not experience pain. i have not experienced pain--but it doesn't feel quite like there's not pain to be had--it simply feels like those frequencies have been blocked from my range. they hover around me, empty and intolerable. my perception weaves around the absence, clucking and rustling, an insidious omen of things to come.
