Sound Reproduction System




US2008130905



A sound reproduction system comprises a left and right speakers located in close proximity, and a sound processor which provides audio signals to the pair of speakers. The sound processor preferably derives a cancellation signal from the difference between the left and right channels. The resulting difference signal is scaled, delayed (if necessary), and spectrally modified before being added to the left channel and, in opposite polarity, to the right channel. The spectral modification to the difference channel preferably takes the form of a low-frequency boost over a specified frequency range, in order to restore the correct timbral balance after the differencing process. Additional phase-compensating all-pass networks may be inserted in the difference channel to correct for any extra phase shift contributed by the spectral modifying circuit. The technique may be used in a surround sound system.

An optimal listening position for the multi-channel audio sound system is determined. A listening area and other audio playback controls may also be defined or modified by a listener. During subsequent audio playback, an imager captures images of at least a portion of the listener. When the listener has moved to a position that is different from a previous position, one or more audio parameters are adjusted for at least one channel in the multi-channel audio system in order to reposition the initial or previous optimal listening position to the current position of the listener. When the listener moves outside the listening area, an out of bounds response is initiated to disable or control the audio playback until the listener moves to a position within the listening area.

Certain aspects relate to providing an at least one audio source to at least one user. Certain aspects relate to selectively modifying an at least one first sound source to be provided to the at least one user, wherein the at least one first sound source is combined with an at least one second sound source, and wherein the selectively modifying is performed relative to the at least one audio source based at least in part on at least some specific information of the at least one first sound source. Other aspects relate to selectively modifying the at least one first sound source to be provided to the at least one user relative to the at least one second sound source based at least in part on at least some specific information of the at least one first sound source.

Which File Sharing Program Should You Choose

There are a number of reasons you should look for when choosing a p2p or file share program. The first is to see if it is easy to use even someone with little knowledge of computers, the program should be easy to use for anyone to find and download the music, movies and tv shows. They should be able to burn media directly to disk straight from the program. Making it a quick and easy way to get the files you want.

They need to be fast. Most people who do p2p file sharing use torrent files. These files allow you to download pieces of a file from everyone who has it. It is a great way to share files and you can often get really hard to find or obscure things in this way but it can be a bit of a pain and often times can take a long time to download. The torrent programs also take up a huge amount of systems resources slowing your internet connection and your computer down.

Some programs are not as fast as direct download but you have greater access to the files you want to download. You also do not have to pay per song, monthly, or bandwidth download fees. You can download for free or use the pro version for more advanced features.

It comes with burning software. You can now download and burn all with the same program saving you time, and space on your computer. Some file sharing programs show you what files are licensed as so you can protect yourself when it comes to copyright infringement.

It uses one of the largest file sharing networks in the world to provide you with everything you are looking for including games. You can download just about anything. Even books can be found for download. It incorporates the lasts technology to sort and organize so that you get access to the files you want. It also lets you see the connection speed listed of the people who have the file.

This allows you to choose providers that can provide you with the fastest download speed possible. High connection speeds equal more bandwidth and that means that you are able to download and enjoy faster.

Because you are downloading from multiple sources you can often listen or view the parts of the file that you have already downloaded before the file is even finished. This is not recommended since all files should be scanned prior to use and it does eat an incredible amount of systems resources to do so. However, it is possible and a great way to make sure that you are getting what you want.

File sharing programs help protect you from copyright infringement by placing licensing symbols next to the files to let you know which files are under what type of license. It also provides a listing to the copyright office to allow you to check to see if a file with no licensing symbol is something that can be safely downloaded.

Finally, file sharing programs allows you to try before you buy helping to save you money in the long run by providing you with a way to try out new artists and songs before you purchase them.

Microphone Techniques And Drums

Recording drums can be a challenge both to the mics and record. So, we need to have a good idea about the techniques that can help us to get a better result. While recording one thing should be kept in mind: if the drums are good, then everything else would be perfectly all right. That means everything else can be fixed later and the take will be perfect.

Various microphone techniques actually affect how much bass, midrange, and treble that we hear in the monitored sound of a musical instrument. There are various points that one should keep in mind while deciding the microphone techniques. The mic choice and placement affect how distant the instruments sound in recording and how much background noise is picked up. But there are no hard and fast rules about where the mics should be placed. If the placement of the mic sounds good to the user then that should be the correct position to use them.

There are various techniques of microphones that can be used in various environments to record drums. Let us learn those in details. Like in the home studio environment the most common and the most successful way to get a perfect sound is to use the triangle miking style. This style involves three mics, hence called triangle. The first mic is placed on the kick drum, and the other one on the either side of the kit. This method will allow catching us a bit of the drum kit.

Before using the microphone technique we need to know what kind of sound output we prefer, such as whether it is big and boomy or round and subdued or tight or punchy? Then the technique will be different while capturing the sound.

If we want big and boomy sound the mic should be placed around two inches in the front head of the drum or away from the head pointed at the center of the drum. For getting a round and muffled sound the drum should be stuffed with a large piece of foam. If the position of the mic is placed in such a way where the halfback is striking out the tight and punchy sound will be recorded.

But this kind of method has one drawback. Some kind of weird lower mid unpleasantness will come, but that could be rectified during the post production stage. In any case the microphone should not be placed in any other direction inside the drum because sound bouncing all around the waves will end up canceling themselves out, thus resulting in loss of volume and tone.

But the microphone techniques will change when the type of drum changes. The above technique could only be used for kick drum only. Setting the microphone for snare drum will definitely be different. In order to record this kind of drum we need two microphones. But just placing the microphone on the front of the drum is not enough. So, planning is needed to decide where the mike should be placed. It would be a good idea to place the bottom mic exactly to the opposite of the top mic. Before the recording starts just turn over the mike on and off and then a decision has to be made about which setting is delivering the perfect sound.

How to Camp Out for Concert Tickets

Has there ever been a concert you were just dying to go see, but by the time you got through on the phone with the box office, the tickets were all sold out? Well get in line! No, really! For some shows, you have to camp out at a ticketing box office overnight to be in line early enough to grab a ticket.

So often today, the demand for concert tickets is larger than the ticket supply. So, if you want those tickets, you have to be one of the first people in line. Of course, there is always the phone and Internet, but in my experience, I've always had better luck, and better seats, camping out in line.

First, and most importantly, after you've picked the concert you want to see, you need to find out what date and time it goes on sale. The most common on-sale date/time is Saturday mornings at 10:00 am. But, of course, this may vary, so double check. For many performers, there are pre-sales. However, the codes for those sales are usually provided by a fan club membership, which costs extra money. And in today's economy - who has that?

Secondly, you need to figure out where you're going to buy the tickets from. There are usually only two options here: Ticketmaster, or the venue box office. You could always get your tickets from a secondary ticket broker, but I'll get to that later. Ticketmaster has box offices all over the place. So, it would be best to find out which is closer to you: a Ticketmaster location, or the venue itself.

Okay, so now you know where you're going and when you're going! Good! But you're probably still wondering how early you need to get there, huh? Well, that all depends. If it's a super popular concert, and it's sold out the last few years in a row, or in the previous cities, where it went on sale first - it's probably going to be an overnighter. And that's why you're reading this anyway - right? So, get your bags packed and grab some friends!

Plan on getting to the location the night before the tickets actually go on sale. In some cases, you may need to get there at least 24 hours before, but let's assume it's just an overnighter, and you can get there in the evening, when you get off of work or school, whatever the case may be. The most important thing is a lawn chair! Get that first! Below is the list of other necessities, and any notes I can think of.

Lawn (or camp) chair - once you wake up in the morning, you'll probably have to take your tent down, but there will still be several hours of waiting ahead of you. Yes, you can stand or sit on the floor, but trust me, after about two hours, you'll wish you had one of these!

Tent - you might want to check with the location before you bring this. Some places have ordinances against using them in public places, like outside of a store. But, it is helpful to have, in case you are allowed to have one.

Sleeping bag/blankets/pillow - again, how many you need will depend on your comfort zone. Some people only need a sheet to be able to sleep anywhere, some need a little more, so bring whatever feels best for you. And remember, you can always leave stuff in your car and get it only when you need it. No use in hogging the sidewalk if you don't need to

Water/food/drinks and a cooler - Again, the amount you'll need to bring depends on you. Just remember though, you probably won't have access to a refrigerator or any heating device (microwave, oven, toaster), so bring stuff that doesn't need to be heated up.

The cooler, obviously, will keep things cool. Bottled water, sodas, juice boxes, sandwiches, chips, pretzels, and dip are all great things to have. You could always call for pizza delivery, but I have found some chains don't deliver unless you have an actual address for them. You could always use the location address, but again, keep it simple.

Money - Yeah, don't forget you have to pay for those tickets

Friends/cards/games - You will get bored. And if you're standing in line by yourself, you'll get real bored around all those strangers. Although, conversations are usually struck up and people tend to bond over their shared experience, it's still best to bring someone you know along with you.

Alright, so now you should be packed up and ready to go! Another great reason to bring a friend is that you'll have someone to hold your place in line. So, grab your friend too and get to the box office! As soon as you get there, stake out your spot in line. Set up your tent, or whatever you have. Then, get comfortable.

I did wait in line once for HFStival tickets, and the woman at the front of the line had been doing this for years. So, she started a list - as soon as someone else got it line, their name was added to the list. This helped to keep things fair in line - there was no "cutting" the line; everyone knew who everyone else was, and where their spot was. You could do this, if you're first in line, but don't feel that it's required.

So, assuming you've made it through the night, wake up early and put your tent and other bulky items back in the car, or out of the way somehow. Once those doors open, you don't want to be tripping over someone's stuff, trying to get in the door. Conversely, you don't want your things to be trampled. Also, once all the bulky stuff is gone, the line seems like it gets shorter - YAY! It doesn't actually - you're just closer to the people in front of you, but by then, any seeming success feels great!

Set out your lawn or camp chair, and get ready to wait some more. Hopefully, someone in line will offer to make a coffee and bagel run, or you could do this yourself. Again, if you have that friend with you, he or she can hold down both of your spots while you go to the coffee shop, or wherever.

Once the doors open, get your butt moving to get those great tickets! Once it's your turn, the ticket agent (the person behind the counter at the ticket machine) will ask you how many tickets you need, and then will tell you what seats are available. Get them! The seating options only get worse the longer you wait. Then, pay the money and enjoy the show!

For those who were unsuccessful, or who don't feel like doing all that work: The secondary ticket broker will be your best bet. A secondary ticket broker is not affiliated with the box office, performer, or venue in any way. They are a company that buys and sells tickets on the secondary market. So, the prices for the tickets will probably be higher, but you'll have a variety of seating locations (want 3rd row on the floor? No problem!).

There are many secondary ticket brokers out there. However, make sure, if you decide to purchase tickets this way, that the broker is registered with the Better Business Bureau, and the National Association of Ticket Brokers. You want to make sure you're buying from a legit place, after all. Also, let's say you waited in line and got those great tickets you wanted, and for some reason, you can't make it to the show after all.

Ticketmaster and most box offices do not have refund or return policies. Again, this is where secondary brokers work to your advantage. Most brokers also buy tickets. So if you can't make it to a show, call a broker, and see if you can't at least get your money back by selling them your ticket!

Sound Reproduction System




US2008130905



A sound reproduction system comprises a left and right speakers located in close proximity, and a sound processor which provides audio signals to the pair of speakers. The sound processor preferably derives a cancellation signal from the difference between the left and right channels. The resulting difference signal is scaled, delayed (if necessary), and spectrally modified before being added to the left channel and, in opposite polarity, to the right channel. The spectral modification to the difference channel preferably takes the form of a low-frequency boost over a specified frequency range, in order to restore the correct timbral balance after the differencing process. Additional phase-compensating all-pass networks may be inserted in the difference channel to correct for any extra phase shift contributed by the spectral modifying circuit. The technique may be used in a surround sound system.

How To Judge The Sound Quality Of A Speaker

Speakers are tools that deliver sound. While listening to any kind of music or watching any movie, speakers are necessary. To get the right feel of the music and movie, you need to have a good speaker.

A good speaker means a speaker of good sound quality. Not all of them are equally good. So you need to be very careful while buying them. In this article, we will tell you how to judge the sound quality of a speaker.

A good speaker does not have any private sound. The job of a speaker is to deliver the sound exactly the way it is in the source. It will not provide any extra sound. If it does, then it will not be considered a good speaker. If it makes the violin or string sound edgy or if it creates an artificial bass for the male voice, then also it will not be counted as an effective speaker.

Midrange is very important for human listening. This is the range that we hear most clearly. A good speaker must be able to deliver this midrange smoothly and that too without any kind of harsh sound. If the lead portion of a guitar sounds harsh or the midst sound becomes muffled, that means the speaker is not of good quality. In this case the music also will not seem realistic to you.

There are some other ways also to judge its sound. If you are listening to a female voice and if you find that it is not sounding clear, then you will get hint about the poor quality of the speaker. But if you find the sounds too much clear or shrill and if you find an extra emphasis on the S&T, then you can definitely come to the conclusion about the bad quality of the speaker.

A very effective way to judge the quality of a speaker is to listen to chorus songs. There has to be four parts in a chorus. Basses and tenors of the men and sopranos and altos of the women. In a proper speaker, you will very easily be able to distinguish all four of them. If the speaker is not good, then it will produce a very blurred sound.

When you are buying a speaker, then you must check the center channel speaker properly. A balance between the center and the front right and left speakes is very much important. If it does not happen, then the music will not sound well balanced.

Experience helps a lot on judging a good speaker. If you are experienced and listen to loudspeakers very often, then it will be easier for you to understand when the speaker is not sounding well. And then you can complain to the manufacturer.

But this is not all. If you want to know how to judge the sound quality of a speaker, then you must be aware of the branding. Make sure that you are not buying them from just anybody. Go for reputed brands, even if they are expensive. It will give you security and will make it an enchanting experience to listen.
