I am so happy to announce that, with little more luck I will become an audio contributor on IS. 2 of 3 of my audio samples are accepted, and one is rejected. Can you guess why? Ohhh, I'm sure you can. Here it goes: "The audio file you have uploaded contains, clipping or distortion artifacts"
 ;D I thought I will get away from artifacts, but seems that they follow me everywhere  :D
Anyway, I'm so happy I will become an audio contributor. Music is my first love. Photography was second...and now I can have both of them ;)

Congratulations whitechild! :) I am one of the lucky ones who has had an opportunity to hear your music and I know that IS gains a lot with your contributions!

It's great to see when somebody's dreams come true!

Cheers!

congrats!

I wonder what type of audio files stock market wants. What for? What is the use for them? Is it sound effects for cartoons, or real music?

Thanks Peter.
What market really wants, I will see after some time. But IS wants everything, from simple samples of sound, to whole melodies. So, anything from sound of everyday sounds to compositions can be accepted. They want it in vaw or aif format, and 44100, or 48000Hz 16bit audio. It can be mono or stereo. I guess people need it for different things, like commercials, intros, effects...etc

Hey SJ,

 Doesn't surprise me a bit you have a lot of toilet flushing audios. Do you record a new one every day  ;D

Only the one, actually, thanks.  But I bet it corners the market.

 I would imagine so. I have a very disturbing image of you huddled with a mike and your face buried in the commode. Oh well anything to make a couple of bucks I guess. Did you give it a good plunge when you were done. ;D

Oh-ho-ho, Jonathan, your wit is intoxicating!  You paint quite the fanciful image. ;)

LOL I heard it in the new uploads around 2 months ago. It's a master piece  :D

One of the funniest topics in a while. Would love to see a Monthy Python episode about audio artifacts! :P

Hahaha. In Europe toilets are bit different than in America. They are with less water in it. So, we in Europe have the ability to even record toilet flush with sound of toilet brush :D

Just curious about one thing... Which side everyones water toilet twirls. Clockwise or counter clockwise. Maybe people in other hemisphere see their toilet water twirls the other way... Just did a test and it twirls clockwise

That's a myth.

Quote:

"Draining in bathtubs and toilets

A misconception in popular culture is that water in bathtubs or toilets always drains in one direction in the Northern Hemisphere, and in the other direction in the Southern Hemisphere as a consequence of the Coriolis effect. This idea has been perpetuated by several television programs, including an episode of The Simpsons and one of The X-Files.[19] In addition, several science broadcasts and publications (including at least one college-level physics textbook) have made this incorrect statement.[20]

The Rossby number can also tell us about the bathtub. If the length scale of the tub is about L = 1 m, and the water moves towards the drain at about U = 60 cm/s, then the Rossby number is about 6 000. Thus, the bathtub is, in terms of scales, much like a game of catch, and rotation is unlikely to be important.

Some sources that incorrectly attribute draining direction to the Coriolis force also get the direction wrong. If the Coriolis force were the dominant factor, drain vortices would spin counterclockwise in the northern hemisphere and clockwise in the southern.

In reality the Coriolis effect is a few orders of magnitude smaller than various random influences on drain direction, such as the geometry of the container and the direction in which water was initially added to it. Most toilets flush in only one direction, because the toilet water flows into the bowl at an angle.[21] If water shot into the basin from the opposite direction, the water would spin in the opposite direction.[22]

When the water is being drawn towards the drain, the radius of its rotation around the drain decreases, so its rate of rotation increases from the low background level to a noticeable spin in order to conserve its angular momentum (the same effect as ice skaters bringing their arms in to cause them to spin faster). As shown by Ascher Shapiro in a 1961 educational video (Vorticity, Part 1), this effect can indeed reveal the influence of the Coriolis force on drain direction, but only under carefully controlled laboratory conditions. In a large, circular, symmetrical container (ideally over 1m in diameter and conical), still water (whose motion is so little that over the course of a day, displacements are small compared to the size of the container) escaping through a very small hole, will drain in a cyclonic fashion: counterclockwise in the Northern hemisphere and clockwise in the Southern hemispherethe same direction as the Earth rotates with respect to the corresponding poles."

Correct! If there is no other force than Earth spinning, the watter will always twirl clockwise on northern hemisphere, and counter clockwise on sothern hemisphere. But, that force is pretty weak, and many things can change this state, from shape of your toilet, to giving an impulse to water to twirl to another side, especially because toilettes are too small. But, if they were much bigger, this effect would be more noticable.

God I am glad we are getting this cleared up. I was just about to book a trip to Australia to check FEW!  ;D

Best,
