Dave's post here reminded me how much I like this song, and so I'm posting it here.

Tatsuya Nakatani

Tatsuya nakatani is the bomb.

Imagine building a sonic wall of sound based out of very tiny sounds. Starting from excruciating silence and building up tension with subtle sounds ranging from mouthpiece-less trumpet air rushes and gurgling noises to drones from bowing a giant gong, blowing, scratching snare drums and cymbals, bowls wobbling and tibetan bowl chimes, a woman making howling and gutteral vocal sounds as if she is losing oxygen, electronic warbles eminating in the background, an amplifier faced up with a sympathetic snare drum amplifying incredibly tiny brush noises on the snare drum, a bass clarinet blowing and making inharmonic noises, feedback drones, metal on metal cymbal scrapes circling and resonating against drum heads...

There were periods where the sounds were so harsh and delibrately slow your hairs stand on end and you wince from pain; other moments where the music is trancelike and peaceful and all thoughts clear from your head, and other moments where the sound of silence was so deafening and the anticipation of the whispery scratch noises from fingernails on a drumhead caused you to lean forward in your seat. Inorganic, industrial-like noises juxtaposed in the same breath as organic and lush nature-like sounds. Wicked stuff.

A reminder to my future self (time shifted and added to my original self)

Over a year ago I was probably at the top of my game in terms of audio k-nowledge. I had gotten through the weed-out and fluff courses and started taking the harder-yet-interesting audio and signal processing classes. Anyway, I remember thinking that I should post a picture as a reminder to my future self that at one point I used to know stuff. What you see above is a block diagram describing a mathematical algorithm for an audio process, called an all-pass filter. An all-pass filter, when applied to a sound, will not make an audible difference. In other words, you listen to it before and after you apply the filter, and it sounds the same.

What's cool about it is that it works "behind the scenes". It changes the time information of the sound for certain frequencies. By pushing and pulling the time information for the sound and adding it to the original sound, certain frequencies will amplify or get cancelled out. Kind of like how sometimes when waves in the ocean hit each other, depending on when whey crash into each other the wave will get twice as big or will cancel itself out. The below diagram takes the sound, changes some of the time information for some of the frequencies, then adds it back to itself.

You end up getting a boost or reduction in sound at a given frequency:

It's like magic. Crazy stuff. Shout out to partner-in-crime, Jason Laska who is holding it down at Rice university, inventing crazy stuff that will soon make him famous.

Flying Lotus

Vic from UC Hip Hop sent me this track today. It's this California producer called Flying Lotus. It's a pretty drunk dusty/electronic/hiphop sound, kinda like if you took Madlib, J Dilla, and Prefuse 73 and put them all in the same room one day. Apparently he is related to John Coltrane and Alice Coltrane...cheater!
