How large a file is a 128 kbps MP3 of John Cage's 4'33"?

You know, that’s the one where he recorded 4’33" of silence. I thought it would be interesting to see how well silence compresses.

Anybody got the CD to rip?

There’s one here - 4MB.

I think it will be dependent on the arrangement; if it is being played by a large symphony orchestra, the silence is likely to be more complex (and harder to compress) than, say if it was being played by a string quartet.

4:33 is 273 seconds. At 128 kilobits per second, you’re looking at 4,472,832 bytes, which is roughly 4.25 megabytes.

Constant rate encoding is constant. Doesn’t matter what you’re encoding.

Now, if you were to run that through a variable rate encoder, it would probably be a bit smaller.

Thanks for that reminder, ultrafilter. I knew that. :smack:

Anyone want to take a whirl at encoding it VBR style?

Well it’d have a pretty small dynamic range even compared to parlour music. But how silent can it be really? What’s the signal to noise ratio on a CD, there’s gotta be some hiss?

How about a cover version CD, like the Aussie ‘Stairways’ one which is nothing but Stairway to Heaven covers?

**4’33’ ** as performed by:

Berlin Symphony Orchestra
Chronos quartet
The Darkness
Britney Spears
Elvis - no problem with keeping really quiet.

With a little organisation you could reform the Beatles!

How would it sell d’y think?

Ok, I just created a 273 second, 16-bit, 44100 Hz, stereo wave file of silence – size: 48,157,696 bytes (100.00%).

Encoding it with a LAME mp3 encoder, VBR, joint-stereo, highest quality – size: 1,087,529 bytes (2.26%).

Encoding it with an Ogg encoder, highest quality – size: 28,884 bytes (0.06%).

Recording silence seems sort of pretentious to me. What is he trying to say?

He sounds like the musical equivalent of an “artist” whose masterpiece is a blank canvas.

That silence isn’t as silent as we tend to think it is. Maybe. Among other things. (If you could boil its message down to a sentence, it wouldn’t be much of a piece, would it?) From one website:

And from the NPR 100 page:

You may or may not find it pretentious, but its importance and quality are open to debate. I’ve never heard it performed, so I don’t really have an opinion. I can’t decide if I’d be bored out of my skull or entranced.

Knowing that it’s just silence, How small could it be?

That is, you just wrote the headers for the MP3, vorbis, etc. necessary to make 4m33s of silence?

In addition to the headers, you need the actual recording itself. Otherwise, there’s nothing there.

I would take Pleonast’s numbers as reasonable lower bounds.

As well as affecting your perception of silence, a performance of the piece screws around with your perception of time.

By the way, it’s a common misconception (as in the last quote by Interrobang!?) that the performance should last for 4 mins 33 secs. The title comes from the duration of the premiere - the performer is free to make the three movements (yes, it’s in three movements :wink: ) whatever length they choose.

I wager the midi version would be pretty compact:D.

240 bytes :smiley:

I have yet to hear this composition performed live. Oh sure, you can settle for lesser performers (there are “cover versions” by the London Philharmonic, The New York Symphony, The Harmonica Rascals, etc.) Still, I had always wanted to hear this conducted by the maestro himself. Sadly, Mr Cage passed away in 1992 so I’ll have to settle for lesser attempts at this complex work.

It seems that some of you are not familiar with the works of John Cage. Perhaps he could be best described as Andy Kaufman with an orchestra.

And if you are wondering why he chose 4 minutes and 33 seconds of silence?
This is 273 seconds of silence and -273° Celsius is absolute zero. Supposedly, this symbolixes the cessation of all motion. (And for the SDMB nitpickers I know absolute zero is -273.15° Celsius. Thank you)

There’s no evidence that this is anything other than coincidence.
On a separate note, I’ve disproved my own earlier post through googling - the first performance did list the piece as 4’ 33", and also the individual timings of the three movements. It was some years later than Cage stated that a performance of the piece could last for any duration.

I am posting this link to show that you are right http://www.fact-index.com/d/de/definition_of_music_1.html
Sure, I found other links that do mention the absolute zero connection, but none are verified as originating from John Cage.
I believe the first time I heard of the absolute zero “symbolism” was in an article by Martin Gardner in an article entitled “Nothing”. (I’m sure most “Dopers” are familiar with Mr Gardner’s work as a recreational mathematician. Seems even he was taken in by this myth).

That link actually gives an excellent, concise description of the piece…and I liked this comment:

So please clarify- do these (any) sounds actually appear on the recording, or are they contributed by the listening environment?

Note to self: people will pay for anything, including nothing.
