Week 6

I discovered that you can save an audio file as txt format, which then has a single line header (e.g. [ASCII 11025Hz, Channels: 1, Samples: 287448, Flags: 0]) and then one line for each sample with a single value (e.g. 0.00781) on each line.
The numbers must represent both pitch and amplitude.

Here’s an original and with all the numbers sorted

Headers are in uppercase, so changing all characters to upper case left the headers intact while making everything lower case ended up messing them up.

Changing character set on the Sopranos file made it unreadable (even though I left the header intact) while it had almost no effect on the honkytonk file.

Electronic Music that tries, and fails

15-year old invents ultrasound mosquito larvacide device

The grey album link posted this week on the list is better than the one I had a week or two ago.

It’s much better after a few listenings. The first time I thought, “I wish that guy would shut up and let the Beatles play.”

But now I can hear beyond the original songs and appreciate the new arrangements, and like them all (though least of all ‘justify my thug’, there’s some actual singing on the vocal track that doesn’t match the dubbed-in music)

The with this kind of mix is that the melody supplies the rhythm and the bass line provides the narrative, just the reverse of most older … Read the rest

Secrets of Beating Off Explained!

Explanations of the sounds below

3.mp3 100Hz + 101Hz = beat of 1 sec.

4.mp3 100Hz + 102Hz = beat of 0.5 sec.

5.mp3 100Hz + 101Hz + 103Hz = 3 beats per second, with an emphasis every third beat (3/4 or waltz time).

6.mp3 100Hz + 101Hz + 104Hz = 4 beats per second, with a deemphasis every fourth beat (quasi 4/4 time).

7.mp3 100Hz + 102Hz + 105Hz = finally getting interesting. I’m not sure I can describe it.

Week 1

Careful listening.
Step 1 - listen far.
Listen first to sounds near you, then proceed outward to the edge of your perception, attempting to hear sounds from as far away as possible.
Step 2 - listen close.
Find a repeatable sound, like footsteps, a keystroke on a keyboard, etc.
Listen as closely as possible to this sound, attempting to perceive the sound not as a singular sonic "icon" but as a complex phenomenon with many components.
Write down your observations and be prepared to share them in class next week.
Also, record a short sample (1-5 seconds) of the close listening, to present in class, and post it in your sketchbook as /1/1.mp3

The far sound I chose was a rope from a flagpole … Read the rest

Sustainable Electrochemical Energy

If the goal is sustainable energy, where might we find it?

We all know about the possibilities and realities of solar, wind, and to a lesser extent tidal and geothermal power, but I thought there might be another untapped and under-researched area: junk yards.

Note: all images have been lost in the ether

Millions of tons of purified metals are discarded each year* in landfills, in the form of construction refuse and personal and industrial appliances.

These metals were expensive to mine and purify, and represent wealth to some degree, except for the fact that they are scattered about.

But in some developing countries, where scavenging objects is part of daily life for some people, and electrical energy is often in short supply, electrochemical energy from … Read the rest

m-Box — Electronic Music Box

The child’s version of the m-Box will be smaller, plastic, and as stated eariler, will rely on markings on paper rather than holes.

The range of notes will be greater, as will the number of possible notes per composition.

This version will be battery-operated.

Conspiracy Laid to Rest

I did something today.
I made coffee from previously-used grounds.
Experts say this would yield sour, bitter, terrible coffee.
In fact it was fine. It was weak, but not bad.
The idea came to me from having used a French press for my coffee for a long time. Often I leave the grounds swimming in water for up to 15 minutes before I depress the plunger.
Drip-coffee is based on the premise that coffee should have as little contact with water as possible.
Many flavors are filtered out of the coffee using the drip method, some bad and some good.
I think drip coffee may be better for lighter roasts, but I prefer to give the gruonds a … Read the rest

Quest for Curiosity: Qrio


Computical Physicing

Week 16

Cooking can be fun, but I’m wary whenever I see recipes that include steps such as “pat dry” or “mince finely” or “let sit for 45 minutes“.

I don’t mind stirring until well-mixed or chop into large chunks – coarse violence is fine, I just don’t like steps that require precision.

My favorite recipes include the word ‘dump’, as in, “Open can. Dump contents into bowl.”

Or better yet, “Dump contents into mouth.”

‘Pouring’ suggests some amount of care, while ‘dump’ means it doesn’t matter if some falls on the floor, if you leave some in the can to eat later with a spatula.

The latest humanoid robot (from Japan, of course) is named Qrio … Read the rest

Computers that read your mind: Playing Pac-Man on thought-controlled computers

They stole my idea.

It is said that mycologists have the highest incidence of poisoning by mushroom.
Their confidence leads to carelessness.
That’s been the explanation for my recent failed efforts – sometimes when I’m sure I can do something, I don’t try.
Other times, I don’t know what I’m doing, but at least I know that I don’t know, and then I try and succeed.
