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.

It Pays To Have A Skilled Audio Visual Consultant Help You Choose Your New Home Cinema System
A quality audio visual system can make all the difference to a home or office.
But being able to afford the most expensive components and being able to change a plug are unfortunately not the only prerequisites. In order to set up a fully functional system that performs to its capacity, it pas dividends to consult with a home cinema specialist.
If you speak to the right kind of people, you'll hear that buying and configuring an AV system is part science and part art.
In order to get the best out of a high quality audio visual set up, you need to be familiar with the technical aspects of the components and the manner in which they're utilised in combination with one another. As well as this, you will need a little bit of creative flair for making the whole setup as good as it possibly can be.
While it may seem like a daunting task, there is no reason to start panicking. If you live in a city, help will be close at hand as most cities will have large numbers of home cinema specialists.
While there may be a strong temptation to go and buy your set up from a high profile high street chain, it is unlikely that they will give you the level of service you deserve.
So look a little harder, do some proper internet research and find an entrepreneur who has made a business out of his passion for all things audio visual. As well as getting great advice, there's a strong chance that the person you are dealing with will be happy to visit you at home or make a trip to your office to set up a demo of the equipment you want to buy.
And frankly, given that you'll be spending rather a lot of money on your new home cinema or board room AV set up, you really should insist on having the rig tested in the environment it will be installed before you commit to it.
Although setting up a quality AV system is an expensive exercise by its nature, a decent home theatre specialist will find a solution that won't cost you the earth, while also not compromising on quality or efficacy.
You should be able to find good advice wherever you are. And if you really don't know where to start your search, you might as well kick it off with Google. Naturally, use a local keyword to facilitate your search. If you live Cape Town, do a search for "Cape Town audio visual company" if you're in the Bay Region of LA, look for "home cinema consultants Bay Area".
It's unlikely you'll get a perfect set of results back, but it should throw out some good local AV companies whose advice will not only helped you find a great system, but it should cut down the stress of sourcing your home theatre and save you money into the bargain!

New Audio Equipment for Conferences
Conferences are big in many companies. Those who are constantly using such equipments, building their own set up can be an advantage. If you think your business can benefit from such investments, the rest of this article will give you just a few pointers but will be beneficial in deciding if building a new audio equipment set up for a conference should be considered.
The basic concept of a simple sound system consists of sound input devices, output devices and amplifiers.
Input Devices
These are microphones, the most popular of which are the dynamic microphones. This is a wired microphone device commonly seen in every stage performances and in musical television performances. A wireless microphone is the same as the dynamic brand but without the connecting cables. These have an FM radio transmitter device to send signals thereby also called as a radio microphone. Lavalier microphones are the hands-free devices which can be seen being used by television newscasters attached to their blouse or suit also called as lapel. Most lapels now are also wireless, making them the most convenient to be used by presenters who need to be all over the stage. CD/DVD players are both audio and video input devices.
Output Devices
Output devices are loudspeakers. The number of units to be needed will depend on the venue of the conference and the number of expected attendees. These equipments will be the bulk of the whole system. Makers of loudspeakers have come up with lightweight and small designs but maybe unsuitable for a large audience. Investing on a good number of loudspeakers can make your set up most applicable for a wide variety and volume of conferences.
Power Amplifiers
Power amplifiers are the drivers of loudspeakers. Aside from amplifying sounds, most units are also made to protect speakers from signal and thermal overloads. This eliminates the need for limiters which is commonly used to prevent signal overloads.
After acquiring the basic equipments, the next agenda is to assign technicians who can manage the whole set up. Consider putting up a group of not less than 3 people to manage the system while the event is on going. These should be trained technicians who know how to troubleshoot when a glitch arise.
For large companies, investing on a new audio equipment set up for a conference can be a good investment. Renting these types of systems always eat up a big chunk from corporate event budgets. But for small and medium-sized organizations, renting these equipments can be costly. Spending for the maintenance and putting additional people on the payroll list entails losses instead of a gain.

M-Audio BX5a - Bi-Amps Are What Makes The Difference
Studio reference monitors can easily cause arguments among audio engineers. There are many different opinions on what the perfect speaker should have. Should you spend money on a great sounding pair of speakers that have their own unique sound? What if you do a mix on them and your music doesn't sound so good when played through some other speakers?
The fact is any decent studio, large or small will not ever just rely on one pair of speakers, that's just too risky. You need a crappy pair because most people listen to music on this kind of system, whether in a car, portable player, headphones etc. Maybe not really bad system but we're not talking about audiophiles here.
You need another pair that are pretty good with no coloration in the tone, but a nice natural response. Fortunately there are very decent studio monitors that fall into this later category and without a big price tag. After much research and testing I can say the M-Audio Studiophile BX5a's do a very nice job of this.
M-Audio has found their place in the market, delivering good equipment at a very good price. They're not competing with the high-end market where components are in the $1000's range but rather manufacturing products for the professional musician and home recording project studio.
Let's face it, if we all had to spend a few grand for every component needed to put together a home recording studio most of us would never get it finished!
The Difference is in the BX5a's Bi-Amps
What you won't find in lower speaker models such as the M-Audio AV40's is the bi-amp system. This means that both the high end and the low end speakers have their own dedicated power which makes for a much better efficiency in frequency response.
This equals better sound and that's what it's all about. The lower-end speakers have a single amp driving power to both the high and low speakers making them sound not as clean.
Considering that the M-Audio Studiophile 70 watt BX5a's cost about $100 more than the AV40's it's well worth the difference when you hear these two studio reference monitors side by side.
Depending on budget and room size M-Audio also makes the Studiophile BX5a Deluxe which means that they've added even more power making this deluxe model 130 watts power rating.
Regardless of which studio monitor you'll be using on your upcoming mixes, wattage rating aside, don't by-pass the bi-amp!

The Coaxial Audio Cable Review
These past few years, the coaxial audio cable has gotten deep improvements and offers a huge variety of cables created for your best fit. Today's audio devices don't use analog signals to create sounds, as the old ones did, but use digital signals derived from data, namely, 0's and 1's. The digital coaxial audio cable is manufactured with the aim to preserve and transmit the digital signals and to maintain the highest possible quality.
A coaxial audio cable is used to convey multichannel audio content from sources such as DVD players and satellite receivers to other devices which can decode that content, such as A/V receivers and DACs. Coaxial audio cables are exactly the same, in terms of their design and performance, as 75 ohm digital or analog video cables. They are 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs at each end.
The right coaxial audio cable is important to making your audio equipment utilize its full potential. If you want to connect components that do not have HDMI connectors, using a digital coaxial cable is an inexpensive and a good way to carry the digital audio signals for right and left stereo or 5.1 channel audio.
Digital coaxial cables don't have to be so expensive as the less expensive cables work just as fine for a fraction of the price; unless you are an audiophile with a $10k+ audio system, you are unlikely to notice any differences in sound quality. This is probably one of the few domains that inexpensive makes not a big difference from expensive.
The new market offers has a large amount of coaxial cables, such as: Belkin PureAV AV20100-06 6-Foot Digital Coaxial Audio Cable, Acoustic Research AP071 Performance Series Audio Digital Coaxial Cable. Mono-price 6ft High-quality Coaxial Audio/Video RCA CL2 Rated Cable, GE Digital Audio Coaxial Cable AV23324, or the Cables Unlimited AUD131506 Pro A/V Series 6-Feet Digital Coaxial Cable.
These cables are easy to install, have impressive sound quality, and do not have interference. They can be installed into most audio systems and stay in place.
Durable build quality, affordable prices, and outstanding sound quality make our coaxial audio cables ones of the best available on the market. They utilize gold-plated precision connectors for optimal sound quality. The affordability and sound performance are top of the lines for these digital coaxial cables; the sound quality is equivalent to many pricier models, but at a fraction of the price. These cables are designed for durability with a thick coating to protect the inner copper wires.
You can say goodbye to the old, unusable coaxial audio cables and make room for the new improved one! The coaxial audio cable that is now on top will never disappoint you. And you will never even think about the last ones or just give it try. After all, the world is evolving, and so did the new coaxial cable. It's time that you do, too!
To learn much more about the coaxial audio cable, please visit www.coaxialaudiocable.org where you'll find this and much more.

Home Audio Visual Experience Worth Setup Efforts
There was a time not too long ago where a "home entertainment center" consisted of a 21-inch TV on top of a small wooden stand with a separate stereo system somewhere close by. But with the technology available to us now, those days have become a distant memory.
As technical evolution would have it, the home entertainment center has taken on a whole new persona. With the integration capabilities between sight, sound and information transfer, a good home entertainment system can create an environment of audio-visual euphoria.
All manipulated by the touch of a few buttons on a remote control device, the rumble of subsonic bass speakers rolls beneath our feet. At the same time, a crystal clear image of a movie or sporting event comes to life on a screen that could be at least five or six times the size of that old table-top model and in 3-D to boot.
Building a Home Entertainment System
The process of building a home entertainment center can range from relatively simple to mammoth depending on the layout of the room and the type of system you desire.
There are many variables, but let's say you're building a basic home entertainment system with slightly above-average audio and video equipment and some computer connectivity thrown into the mix. You will need a large multi-level shelving unit, especially if you plan on using a 50-plus-inch TV. You will also need room for some or all of the surrounding components, such as a stereo receiver, DVD player, any cable boxes. Your shelving unit will have to be large enough to handle all of the HDMI cable required to hook the system together. It must have plenty of holes available to allow for cables to connect to any power sources and adequate ventilation. A/V equipment is notorious for the amount of heat it puts off.
Always keep safety in mind when dealing with electronics. Make sure all power cords are Underwriters Laboratory (UL) classified. When doing anything with power cords or wiring, it's always a good idea to cut the power off to the room you are working in. Never plug too many cords into one power source. It's best to have a surge strip with multiple outlets and a built-in surge protector. This will allow you to assign one outlet per power cord.
Other Components and Cabling
The personal computer (PC) is quickly becoming a routine component within home entertainment systems. There may be some connectivity issues at first glance, but these have been quickly resolved in many cases with the advent of HDMI cables. By making your PC part of the home entertainment system, you can watch online videos on your big screen or play songs from your vast music library using the surround sound system. Your PC can also become a fine-tuning and adjusting source for your home entertainment system.
For many home entertainment system owners these days, one big-screen TV is not enough. There will sometimes be two, three or maybe even more televisions around the house. With the use of a video splitter, the signal from your computer source can be replicated and distributed to multiple screens.
Try your best to keep cabling neat and organized. This is not always easy. Many of the home entertainment systems we come across display a dense jungle of cables and wires. When possible, use cable ties to wrap cords together, trying to make them straight as possible in the process.
In simpler times, there were only a few power cords and "wires" to deal with when configuring home audiovisual equipment into a single system. But the sensory experience today's systems provide is worth all the work that goes into the setup process.

Stacy, founder and owner of Cable & Connector Technologies, is the author of this article about the essential role the HDMI cable, surge strip, cable ties and video splitter plays in creating a home entertainment system.
