That's a whole lot of words just to say something that is plainly obvious.

Almost? I must be losing my touch in my old age. I'll try harder next time.

This was somewhat amusing to me:

http://en.wikipedia.org/wiki/Sampling_rate

Quote:
Because of the Nyquist-Shannon theorem, sampling rates higher than about 50 kHz to 60 kHz cannot supply more usable information for human listeners. Early professional audio equipment manufacturers chose sampling rates in the region of 50 kHz for this reason. 88.2 kHz and 96 kHz are often used in modern professional audio equipment, along with 44.1 kHz and 48 kHz. Higher rates such as 192 kHz are prone to ultrasonic artifacts causing audible intermodulation distortion, and inaccurate sampling caused by too much speed. The Audio Engineering Society recommends 48 kHz sample rate for most applications but gives recognition to 44.1 kHz for Compact Disc and other consumer uses, 32 kHz for transmission-related application and 96 kHz for higher bandwidth or relaxed anti-aliasing filtering.

...

Quote:
48,000 Hz - The standard audio sampling rate used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on. This rate was chosen because it could deliver a 22 kHz frequency response and work with 29.97 frames per second NTSC video - as well as 25 frame/s, 30 frame/s and 24 frame/s systems. With 29.97 frame/s systems it is necessary to handle 1601.6 audio samples per frame delivering an integer number of audio samples only every fifth video frame. Also used for sound with consumer video formats like DV, digital TV, DVD, and films. The professional Serial Digital Interface (SDI) and High-definition Serial Digital Interface (HD-SDI) used to connect broadcast television equipment together uses this audio sampling frequency. Most professional audio gear uses 48 kHz sampling, including mixing consoles, and digital recording devices.

So why do people insist on obtaining 24/96 or 24/192 versions of things then if the higher sampling rates are essentially useless for us humans? Why not have 24/48 instead?

Because sometimes 24/96 versions aren't mastered as gruesomely as CDs so they can be sold for higher prices everytime. It's a goldmine. The format itself doesn't really matter.

 

High-res downloads should be boycotted until the industry dials back the destructive mixing/mastering.

Woah, have you guys watched this before?

yup thats how I found out about all of Mr Winer's writings.

I have a question about harmonics. I know a kick drum with fundamentals at ~60Hz will have harmonics higher up, but will it also have harmonics further down? Say at 30Hz or 40Hz?

AFAIK, if 60Hz is the fundamental, then the harmonics will be in integer multiples of the fundamental.

There is at least one playing technique for subharmonics: http://www.marikimura.com/subharmonics.html  Mostly they are little-used by composers; George Crumb has included them.

Can be heard ~43 secs + here: http://www.youtube.com/watch?v=oPTt5u681so This artist is also playing occasional upper harmonics.

That was fascinating! Thanks for sharing.

It is a shame that that video is isolated in our ghetto here on Headfi. It should be on the front page of the site.

A tale. Bear with me I think it is relevant.

I had a combi boiler fitted a couple of years ago and it has always exasperated me how long it takes to heat the water. Leaving me chucking liters of water down the sink. In contrast to the tank based system it replaced.

A few days ago a friend who is a plumber came and had a look. The only problem he found was that the gas pressure was 1 millibar lower than the manufacturer recommends.

He adjusted it and left.

I was very pleased to find that the hot water delivery had improved. When I next saw the plumber I thanked him and told him that what he had done had improved things.

He said that he was very surprised and doubtful that what he had done could make a difference. ( He hadn't charged me for the visit BTW.) He even asked if I knew of the placebo phenomena!!dt880smile.png

I have realised that nothing has changed. I just became a little more patient and forgiving of my hot water system.

A friend of mine says that as he gets older he realises that everything he thinks he knows turns out to be an urban myth.

I am beginning to think that every decision I ever made about anything is placebo! I am even starting to look at my wife of 30yrs.a little dubiously!! blink.gif

Our ghetto is the sole beacon of truth on this entire website. The rest I read for comic relief. I read this today:

Copper tends to increase bass. Warms up the sound more so I'd picture that being a bad pairing on the 8A. Pure silver cable on the other hand tends to lean out bass somewhat so it may help. But it also tends to take the mids back a little. That depends on your preference though. I also find it to enhance treble and make it brighter.

This particular thread, Skeptico is becoming the last vestige of the sole beacon.
