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.

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.

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!
