As well, the matrix mixer may have been used to route various audio input channels to specific recording channels. 
  Sound — David Henson  
The Sound and the Fury is a 1959 film directed by Martin Ritt.
It is an adaptation of the novel with the same name. 
While shunning Phonofilm, Hollywood studios introduced different systems for talkies.
First up was the sound-on-disc process introduced by Warner Brothers as Vitaphone -- which used a record disc synchronized with the film for sound.
Warner Brothers released the feature film "Don Juan" starring John Barrymore on 6 August 1926 in Vitaphone, with music and sound effects only.
On 6 October 1927, Warner Brothers released "The Jazz Singer" with Al Jolson in Vitaphone.
The film is often incorrectly credited as the first talking picture.
"The Jazz Singer" was the first feature film to use synchronized sound for talking sequences rather than just for music and sound effects, and thus launched the talkie era, but DeForest's sound-on-film system was in fact the basis for modern sound movies.
The Fox Movietone system was first demonstrated to the public at the Sam H. Harris Theatre in New York City on January 21, 1927, with a short film of Raquel Meller preceding the feature film "What Price Glory?
", originally released in November 1926.
Later in 1927, producer William Fox introduced sound-on-film with the feature film "Sunrise" by F. W. Murnau.
In 1928, the sound-on-film process RCA Photophone was adopted by newly created studio RKO Radio Pictures and by Paramount Pictures.

Question: How much do squash balls weigh?
About the article "Squash (sport)", section "Playing equipment".

Candidate passages:
Social scientists who advocate this theory believe that one’s achievement is a product of the motivation to succeed times the motivation to avoid failure.
This means that individuals weigh their expectancy of success with the value they place on that success, or, how well an individual thinks s/he can do and how much doing well actually matters. 
Unlike the latex-based technology underlying the modern lawn-tennis ball, the game still utilizes a cork-based ball very close in design to the original balls used in the game.
The diameter balls are handmade and consist of a core made of cork with fabric tape tightly wound around it and covered with a hand-sewn layer of heavy, woven, woollen cloth, traditionally "Melton" cloth (not felt, which is unwoven and not strong enough to last as a ball covering).
The balls are traditionally white, but around the end of the 20th century "optic yellow" was introduced for improved visibility, as was done years earlier in lawn tennis.
The balls are much less bouncy than lawn tennis balls, and weigh about (lawn tennis balls typically weigh 2 ounces).
The long racquets are made of wood and use very tight strings to cope with the heavy balls.
The racquet head is bent slightly to make it easier to strike balls close to the floor or in corners, and to facilitate a fast shot with a low trajectory that is difficult for an opponent to return.
There are only two companies in the world hand-crafting these racquets: Grays of Cambridge (UK) and Harrow Sports (US) based in Denver, Colorado. 
The Carved Stone Balls have been taken as evidence of knowledge of the five Platonic solids a millennium before Plato described them.
Indeed, some of them exhibit the symmetries of Platonic solids, but the extent of this and how much it depends on mathematical understanding is disputed, as configurations resembling the solids can naturally arise when placing knobs around a sphere.
[http://www.neverendingbooks.org/index.php/the-scottish-solids-hoax.html] There does not appear to be much special attention given to the Platonic solid arrangements over less symmetrical arrangements of knobs over the balls, and some of the five solids do not appear. 
Balls used in urban golf vary relative to each organization and context.
Although real golf balls are used in some circumstances where risk from injury is low, other balls used are Tennis Balls, Squash Balls, almostGOLF Point3 balls (used by Urban Golf associations throughout Belgium), Air Flow Balls, Cayman Balls and many types of adapted or customized balls.
Shoreditch Golf Club produces and manufactures its own design of ball specifically for this game.

Question: What does the survival of a living organism depend on?
About the article "Biology", section "Energy".

Candidate passages:
When someone is interested in how survival is affected by the disease, there is also the net survival rate, which filters out the effect of mortality from other causes than the disease.
The two main ways to calculate net survival are relative survival and cause-specific survival or disease-specific survival.
Relative survival has the advantage that it does not depend on accuracy of the reported cause of death; cause specific survival has the advantage that it does not depend on the ability to find a similar population of people without the disease. 
Commensalism benefits one organism and the other organism is neither benefited nor harmed.
It occurs when one organism takes benefits by interacting with another organism by which the host organism is not affected.
A good example is a remora living with a shark.
Remoras eat leftover food from the shark.
The shark is not affected in the process, as remoras eat only leftover food of the shark, which does not deplete the shark's resources. 
It is fairly clear that predators tend to lower the survival and fecundity of their prey, but on a higher level of organization, populations of predator and prey species also interact.
It is obvious that predators depend on prey for survival, and this is reflected in predator populations being affected by changes in prey populations.
It is not so obvious, however, that predators affect prey populations.
Eating a prey organism may simply make room for another if the prey population is approaching its carrying capacity.
The population dynamics of predator-prey interactions can be modelled using the Lotka–Volterra equations.
These provide a mathematical model for the cycling of predator and prey populations.
Predators tend to select young, weak, and ill individuals. 
Sex.
This chapter is a discussion of theories of the evolution of sexual reproduction.
The common-sense explanation is that although asexual reproduction is much easier and more efficient for an organism it is less common than sexual reproduction because having two parents allows species to adapt and evolve more easily to survive in changing environments.
Brooks discusses efforts to prove this by laboratory experiment and goes on to discuss alternative theories including the work of Joan Roughgarden of Stanford University who proposes that sexual reproduction, rather than being driven by Charles Darwin's sexual selection in individuals is a mechanism for the survival of social groupings, which most higher species depend on for survival. 
The fitness of a genotype may depend on the fitness of other genotypes in the population: this covers many natural situations where the best thing to do (from the point of view of survival and reproduction) depends on what other members of the population are doing at the time.
