Oops, the artist's source code has a bug making the 233 DVDs contain not what he thinks they contain... All his source files [1][2][3] attempt to generate the random noise with: // basically no wimpy numbers - only fat ones if (s > 0 & s -30000) {s = (short) (s - 30000);} s is a Java 16-bit signed short initialized to a random value. His intent is apparently to modify s to generate sound samples in the ranges [-32768…

Did you notice that there aren't logical and in the if statements' expressions, but bitwise and?

Wouldn't it result in something like `if (true & true) {...}` being evaluated, which seems weird?

I sent this to jliat and he had this to say:

"Oops indeed! but not me! :-)

they have confused THREE! works. The 1 TB set of disks was not made using the Java code! but made from samples of Harsh noise.... as MP3 files = 1 TB - Harsh Noise not HNW! Each MP3 being made of random chunks of MP3s spliced together using a VBnet program. The other piece 510 disks is HNW but again not made using the JAVA code he refers to, and this uses .WAV files.... not .AU !!! (it layers randomly HNW noise to create a .WAV)

Now as to the JAVA code - I wrote this must be 6 - 7 years ago as an exercise- but i've just run the program which creates the .AU file of HNW... max value in the file is +32729 minimum -32720... were found in a small chunk of the .AU file.... so?

here is a sample of the .AU file actually produced by the code to which he refers...

-12248 -30299 5627 -12218 6453 6684 6991 6832 6059 -30395 -30301 -30188 -30270 -12141 -30911 -32020 -32664 32208

Now i'm ready to admit i'm no JAVA expert...!!! which is why i use .Net! But this was an exercise in seeing how to make HNW using Java. It was never released as a piece. I used some code I found for making sine waves and plugged in my random algorithm... nothing smart. But it did work! Why it seems IDK.

As a rule of thumb i tend to look at the output of any programs...

Feel free to post this response as i'm not a member of the group, but would think as the code and program is there a simple test run would show its harsh. That my attempt to not use wimpy numbers doesnt seem to work as it should is besides the point. From memory i probably just tweaked these numbers until the results were harsh - that in the above data set (only a small number of samples above) gives a standard deviation of 29101.09796...

If you look at this you can see a plot for the output of the JAVA HNW.... its high! I gave the source so anyone into JAVA could play with this... as i say its not a piece but a by-product on seeing how HNW / Noise has large Standard Deviation and low SNR and as one might expect produces HNW. The harshness being a product of sudden and large changes in values...

In fact i like the fact that in spite of the (MY) mistake it still works - can you fail in noise? :-)

P.S. The JAVA HNW is way too slow to make these big terrabyte files... it would take much longer to write them than they sound when played!!!"

OK - some background...

Reading the thread is interesting! My motivation for the 1 Terabyte work was nothing to do with conceptual art, I wont go into detail but originally conceptual art was the idea that art was essentially a practice of examination of the nature of art, see

http://tallervi.pbworks.com/f/Art%20After%20Philosophy.pdf

This is an incredibly important document (though I don’t subscribe to it now) as it poses the severing of art from aesthetics! (which I do subscribe to)

Unfortunately the media then took the term ‘conceptual art’ to mean any art using any ‘idea’ about anything! Which was usually linked with challenging the viewers idea of art etc. or being ‘interesting’ or smart or ‘pushing the boundaries’… And was based on the misunderstanding of the lack of symmetry in this kind of thing..

1. New art is shocking. 2. Something shocking is new art.

1. might be true in some cases, but 2 does not follow anymore than…

1. New theories in science are often thought crazy. 2. If this is thought crazy its new science.

So my motivation for 1TB– simple

“A man climbs a mountain because it's there. A man makes a work of art because it isn't there.” Carl Andre.

So not a conceptrual work but an OBJECT.

I just thought - could I make a terabyte of noise? I like the discussion about why mp3? The project began many years ago 1990s… using a lap top and VB to write the files. This was so slow that after about 2 days the program would crash… the problem seems not FAT32 but the old VB couldn’t handle files larger than 4gb. Well after several attempts the lap top gave up! Latter of course you see the header of a .WAV file allows for a max of 4gb. (“WAV files are usually stored uncompressed, which means that they can get quite large, but they cannot exceed 4 gigabytes due to the fact that the file size header field is a 32-bit unsigned integer”) So I had two problems, size, and the time taken to write! such a long file. The answer was when I found you can join mp3s and they will play… even using a DOS copy command… copy *.mp3 /B big.mp3 would copy all the mp3s in a folder to one big mp3 – which would then play! (unlike mp4!)

So I created a .vb program (called MUZILLA....) to randomly splice chunks of .mp3s to create large mp3s. The random selection giving different sound files of very large lengths. This would make very big mp3s in minutes not days…. So the project looked possible!

Moreover I found though one can count up to a billion, a trillion is impossible, I am very interested in ‘objects’ which exceed the human. http://www.jliat.com/tg/index.html

http://www.jliat.com/APCDS/index.html

This is bound up with such ideas as infinity, multiverses and a time before and after humans as being the nature of reality. (Speculative Realism) If reality is essentially inhuman – and if art is about our relationship to reality… then I think my work could be considered as being art. Or if not then I’m just messing with what I find in the world…
