There was a time in Europe where SCART equipment was extremely common. This was a standard that was used to connect items such as video game consoles, televisions and stereos. The reason it became so popular is because it was easy. The system took all of those different connections and signals and brought it all down to one signal. Instead of having to try and navigate the several different standards that existed for audio and video, all people had to do was bring everything together using this system and it all connected simply and quickly. It was almost impossible to make a mistake.
Today, the SCART system still exists because people enjoy the simplicity of it and they also enjoy how it allows them to retain the significant investments they have made in their audio and video equipment. Another reason that people still use this system is because, in some ways, it still offers an extremely superior picture quality than any of the other analogue methods that came along after it. Many of the early DVD players that were sold in Europe were compatible with this system because of the crispness of the picture, regardless of what kind of connection the television had.
As people watched their audio and video components grow, the need for SCART splitters started to grow. Today, there are still plenty of people who use this technology simply because it has withstood the test of time. But as they add DVD players and stereo components to their home theatre system, they start to run out of room on their SCART units. These splitters will allow consumers to add more units to their SCART arrangement and expand their home theatre set-up without having to get rid of all of the equipment they have already invested in.

Car Audio Crossovers - Why You Can't Do Without Them?
I've heard the question asked many times before, 'Do I really need a crossover?' Without wasting any time I quickly answer, 'Yes you do'. Whether it's a passive crossover or an active crossover, your car audio system will never sound good without a crossover. I want to make myself very clear here, so before you get confused let's talk about what a car audio crossover is and why you need one.
A crossover is a filtering device which limits the frequencies that reach a speaker. It splits a music signal into separate frequency ranges and sends them to speakers that are designed to best reproduce each frequency range. For instance, only high frequencies would be sent to your tweeters, midrange to your mid range speakers, and lows to your subwoofer.
The passive crossover is very common. It's basically a capacitor or coil installed on the speaker leads between amplifier and speaker that stops certain frequencies from reaching a speaker. It's relatively inexpensive and easy to install.

Adapting A Book To A Screenplay - Indulge In An Audio Visual Experience
Adapting a book to a screenplay can be a rewarding experience for the creative individual who wants to incorporate audio-visual mediums to bring the still characters of a book to life. As a short narration of the entire book, screenplay writing must be carefully planned to capture not only the actions but also the thoughts of characters involved.
While adapting a book into a screenplay, important points of differences between a screenplay and a book must be understood:
1. A book is narrative while a screenplay is to be performed with audio-visual aids.
2. A book contains about 60,000 - 150,000 words on an average, however a screenplay cannot exceed a certain specified word limit. A screenplay is usually 85-125 pages long.
3. A book follows a certain writing style while a screenplay lacks literary prose.
4. A book is an in-depth description of all the characters and other biographical details while screenplays lack that advantage.
Thus, a very important step to begin screenplay writing is to decide what is to be included and what needs to be cut out.
Pointers to be noted while reading a book for its conversion into a screenplay:
• The opening story page
• The key characters

Regarding Home Theater Audio Receivers
When contemplating how to put together a home theater system, one should not forget a crucial component to the audio and visual experience. Home theater audio and video are controlled by a receiver which is the central unit where the inputs and outputs of the home theater are based.
A home theater receiver combines the functions of three components. First, a tuner for AM and FM, in some cases high definition radio or Sirius Satellite or Internet radio. Second, a preamp that controls the audio or video source selected - Blu-ray play, DVD player, iPod etc. Last, a built in multi-channel amplifier that sends the surround sound signals to the speakers and also supplies power to the speakers.
The modern audio visual receiver (AVR) is a complex device, perhaps one of the more complex electronic devices in the home. It has a computer, amplifiers, audio signal processing chips, signal converter chips. Many AVRs have video processing chips as well. The main circuits in an AVR are: Power supply; Processor; Analog Audio; Digital Audio; Analog Video; Digital Video; Amplifier.

Modern Audio Forensics
Forensic audio deals in the scientific and professional investigation (including the technology and tools used) to determine the authenticity of sound where it pertains to criminal cases, as well civil court cases. Based on audio forensics, the results turned up during investigation can be used as evidence in criminal and civil cases that deal with anything from family and neighbor disputes, divorce, extortion and even industrial espionage.
Audio forensics have been used in virtually every case involving a wiretap or recorded conversation that was used in a trial - and that includes the common analysis of surveillance tapes in work environments, particular with disputes between employers and employees.
The Roots of Forensic audio
Before audio forensics was widely used in the professional world and by law enforcement agencies, the practice was focused mainly among the United States government. Linguistics experts and those versed in studying audio would utilize technology during World War II to dissect and analyze the voice patterns of enemies via radio and telephone.During World War II, specialists utilized a spectrograph to plot the frequencies and amplitudes of voice patterns. This practice made it easier to identify individuals of interest and monitor frequencies for important broadcasts or intelligence.

Audio Translation And Its Problems
As the world gets smaller, people find ways to use materials from other countries. However, this requires some sort of translation in order to work well. Audio translation has a number of inherent problems that need to be dealt with on every track.
Unlike a normal translation, the audio version has a number of limitations based on the format of the original material. The biggest limitation is that the translated track must match the original in length. This can be a problem as some languages simply use more words to describe the same concept; for example, French uses about 25% more words to describe the same thing as an English version. This can make for some interesting issues when converting from one language to another and the length must be the same.
Complicating the issue is when the audio must be synchronized with a video track. An obvious issue is when the audio must match what is seen on the screen, but that is usually the simplest issue. A more interesting issue is when there are cues in the video that must match the audio, such as when the number "3" shows up on an instruction video. The same number must appear in the same place in audio translation as well, meaning that the translator must have the same length before and after the number.
If there are 10 seconds of audio before the number and 5 seconds after it, the translation must match that timing; this can make for some interesting timing issues when the two languages have different structures, such as the loose structure of English versus the rather strict one of French.
Another way to deal with the timing issue is to adjust the speed of the track, making some languages sound sped up a little, and other languages sound a little slower. Although there are more precise ways to do it, sometimes it is necessary to resort to some basic tricks in order to get the job done. However, there is rarely a translation issue too tough for technicians to deal with with some trick from their bag. Usually it is just a matter of looking for a slightly different translation, but given the potential issues that a wrong translation can cause, sometimes it is just better to go with a technical trick.
There are other applications for an audio translation, as some translation jobs require that a transcript be made for the client. As a transcript is made as part of the translation process, this is usually not a problem. This just allows for a number of different ways for one group to communicate with another group in a different country, making for a smaller, more intimate world.
