Frameworks Week 11

Ada Babbage: Abba: Aba Cadaba

Heinrich Schenker had some interesting theories of music. One, I believe, was that every euphonious melody begins on the 3rd or 5th and ends on the root.
If you find a melody that does not fit this pattern, by adding or removing notes so that the melody does fit will actually ‘fix’ the melody and make it sound better.

“Feel the beat of the rhythm of the night!” – El DeBarge

Ursatz or Ersatz?


one – ‘mystery rhythm’ alternating with 3, fft=10

two – beat on 4 with more intricate intermediate rhythm, fft=6

three – loose rhythm, fft=12

four – ‘smells like Philip Glass’, beat on 5, 2+3 a là Brubeck ,fft=8

five – bass line with echo of 300ms (slightly longer than delay between beats) ,fft=8

six – dehydrated electronica: two sines (100 & 101) create pulse of 1 sec. double speed and pitch and remix, do again, and again.

Frameworks Week 9

Found quite a few granular synthesis patches online, including ‘sandpaper’, ‘granola’, and ‘Lyon Potpourri’. I couldn’t get any of them to work satisfactorily, though.

I’m using the Cylon sound I used before. I think it was made by quantizing a human voice, so it’s already been processed.

For whatever reason, Max crashed a lot while making these. I’ve never had that problem before.

The main advantage of granuar synthesis seems to be the ability to separate pitch and speed, which are otherwise always inversely related.

One demo had eight grains playing at once. I didn’t notice much difference between 4 and 8, or 2 and 8 for that matter.

Bring in the Noise, Bring in the Skunk

Talking about music is like dancing about architecture

Fifty-Five Noises, some from nature, mostly man-made. The natural ones are most interesting to me.


Wind itself makes very little noise, just a low pitch as the air is pushed against your eardrum.


The sound of wind over a field of grass makes a ‘shh’ sound as the individual blades vibrate slightly.


The sound of wind through trees has a whistling sound, noise with an exagerated frequency or two. This must be the branches or leaves shaping the air.

I tried doing some spectrography on these noises, but since they contain huge swaths of frequencies, the spectrograms ended up just looking like solid blocks with no discernable concentrations, which makes … Read the rest

The Future Stinks

The assignment was to study the style of Terry Gilliam, who was adept at making animations with a minimum of actual animating (note how he never bothers to animate anyone’s feet). So I did virtual cutouts in AfterEffects, reducing color to bring the file sizes down, and made this. (1.5MB)

Now, unfortunately, the format is MP4 – so many players won’t recognize it. You’ll have to save to your desktop and see if any of your players can read it.

I could upload it into another format, but the compression artifacts and file size of the MP4 version are better than they were in any other format I tried.

I’m quite happy with the song. I had also been studying formulae for pop songs (both formally … Read the rest

Compressing Animation Through Color Reduction

I’ve been doing a lot of experimenting with animation compression, looking for the best format to deliver photo-quality moving images while minimizing both the download time and the need for the user to have to bother with external players.

Sorenson Squeeze does a good job, and I was happy with how MP4 files could have such good compression with minimizing the degradation of image quality. However, a lot of players don’t even recognize the format, and players such as Winamp will play the audio but none of the video.

In terms of delivery, it seemed that an animation has to be embedded into a Flash movie if I want to have a majority of people able to see it without trouble.

In terms of reducing download-time, … Read the rest

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

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.
