Noise reduction is that process that deals with removing the noise from a signal. There can be two different types of noise reductions: the process of removing the noise from an audio signal and from a video signal. I don't know if you are aware of that but noise can be recorded by both audio and video devices. For example when you record somebody singing and you use an audio tape, MP3 format or any other method of recording sounds, sometimes you can hear a "hiss" - that's the noise that was recorded together with the other sounds. All recording devices, either digital or analog are influenced by the noise in the background or even "white noise". You can remove that hissing if you edit the audio recording and use special noise reduction software, allowing you to completely remove the noise of the background or reduce it to the minimum.

On the other hand the noise recording can influence the quality of a photo, too. You can see that in the digital cameras as well as in the case of old fashioned film photographic devices. In this case the noise is perceived as a blur on the image. It cannot be seen clearly, but you can remove that effect by using noise reduction software for photos.



Here is an alphabetical list of noise reduction software that will guide you if you want to find the perfect software for you, either as a professional or amateur in this field: Advanced Photo Tools DeNoise MyImage, Camera Bits Quantum mechanic, Imagenomic Noiseware 4, MBS Photo Refiner, Photoshop, Neat image Noise Reduction, Nik Software Dfine, Nik Software Dfine 2.0, PictureCode noise Ninja, Visual Infinity grain Surgery. All the software in this list deals with photography. We will talk about audio noise reduction later.



Noise ninja is one of the most effective and popular solutions for removing noise from digital photos and frames of movies or scanned images. You know what happens to photos at high resolution or on the move or even when the setting is really crowded. But imagine it from the professional photographer point of view. And I'm talking here about newspaper photographers who must obtain very good quality and resolution pictures in order to attract the buyers. If you are a news reporter or photographer you will be forced to make the shooting in all kinds of light, even low or no light, when the people you want to shoot are running or moving.  That is exactly the case with photographers at weddings, sporting events or fashion on stage presentations. The results, however, have to be spectacular. So the real professionals purchase Noise Ninja software in order to remove the noise and grain, but still preserve the detail and quality of the photo.It is compatible with Windows, mac OS X and Linux, so it can be used on almost any computer with great results, either you are a professional or an amateur photographer.



Neat Image, another noise removing software for photos, can be used as a standalone software or as a plug-in for Photoshop. The software is very easy to use and there is a lot of documentation available the helps you step by step. If you already know about all this stuff, you can skip this part and move on directly to the application. But if you are a beginner or an amateur, let the software work with its default settings and don't change anything. After you applied all the filters and got to the end of the application, the best way to judge your result is to put the two photos (before and after processing) and see the difference. In conclusion, Neat Image is a very good choice if you are looking for a software to reduce the noise in your digital photos. One of its strong points is the fact that it is very easy to use and has a lot of documentation and help.

Now I will tell you a few words about noise reduction in audio files. Professional recordings are made in the studio, where the wall are sound proof and there are no interferences from the outside. But if you want to record something outside you will notice all kind of strange things and sounds that weren't there when you recorded the file. This is the noise recorded on your audio file and it sounds really awful. Use a noise reduction software for audio files and you will notice the improvement.



DCSeven and Audio Mentor are just two of the software available that can help you with this problem. Their business is noise reduction, audio restoration and audio enhancement. These products are the best and they are used for audio editing, audio restoration and even audio forensics. You can find all kinds of versions for all kinds of people , amateurs or professionals, willing to pay more or less for the software. Besides the product you also get free technical support and advice. Usually this kind of software is used when people want to preserve some recordings made on phonographs, old vinyl records or audio cassettes. The quality of the recording deteriorated in time and during the transfer a lot of other noises appeared. Well, now it's time to use the appropriate noise reduction software and get perfect sound.

I talked about the use of this software in audio forensics. What is in fact audio forensics? Well, it is that branch of forensics science that analyzes audio recordings that serve as proof during criminal trials. Sometimes the criminal or the victim are recorded by the automatic service of emergency and are then used in order to identify the person. it may also be used to compare two voices in order to see if they are in fact one and the same. This software helps to reduce the noise in the background and get a better quality of the sound, making it possible to identify the person's voice or even to identify special sounds present in the background: the sound of a train, a radio and so on. All these can be valuable information in a murder investigation for example.

I found a different noise reduction software , this time it is used to reduce the noise in the background during a voice call conversation . It seemed really helpful for me, as I have two small children that are really noisy and sometimes I can't hear much when I'm on the phone. SoliCall has developed an innovative and original software for this kind of problems, when you are making voice call conversations, PC to PC, PC to telephone. It reduces the ambient sounds and transmits only good quality sounds.

This being said, I'm looking forward to HEARING from you!

Wi-Fi is an advanced technology that allows wireless internet access to such devices like personal computers, video consoles, mobile phones, MP3 players or PDAs, but only in the area of a wireless local area network that is connected to the internet. This area can be st up to cover different surfaces, from a few rooms to an area of a few square miles. The access area is covered with access points called hot spots, having each an area to cover. This technology is used mainly in homes and offices, but also as a way of providing wireless internet access (either for free or for a certain sum of money) in places like airport restaurants, libraries, internet cafes, hotels, in order to attract customers and offer them the requested services. Many student campuses have also started using Wi-Fi network to provide free internet access to students living there.
<-300x250 Medium Rectangle - center->
Many people have their own Wi-Fi network at home, but not all of them know how to take full advantage of it.If you have this kind of technology available on one of the above mentioned devices, than you have a great opportunity of installing some free software that you downloaded from the internet and this way improve the use of these devices and add a lot of useful and funny applications. And in order for everything to be perfect, all this software is for FREE.

The first thing to do when you have WI-FI technology and want to access a hot spot is to make sure you protect your laptop, computer or PDA you use against any threats that could harm them when accessing the internet in these places. So you should better have an anti virus software or make a Secure Connection With LucidLink that you cal also find for free on the internet. It is an excellent free software application that detects the security settings of the network you want to connect to to and also teaches you how to configure your wi-fi settings properly in order to connect to the network. It warns you if the network presents a security risk and what to do to avoid this.

Palms or PDAs as they are named, are in fact Personal Digital Assistants and were called PalmPilots when they were first released on the market by Palm Computing company ( a division of US Robotics) in 1996. In time they lost the name "Pilot" because of a lawsuit with a famous pen producing company that had the same name. Now everybody refers to these devices as palms. The inventors of palm were Jeff Hawkins, Donna Dubinski and Ed Colligan, the founders of Palm Computing. In fact their initial purpose was to create a software that could recognize handwriting for other devices, but they ended up by developing a different hardware themselves.The first palms did not have infra red port, backlight or flash memory.  However, they did have a serial communications port. Nowadays they are really sophisticated devices of communication, a kind of combination between organizer, mini portable computer and telephone. Of course you need a Palm Operating System to run on palms, but you can also install other kinds of palm software in order to have more features available or to do all sorts of things provided by the respective palm software.
<-300x250 Medium Rectangle - center->

The Palm, or PDA is , as its name shows it, a personal assistant, that is it assists you in organizing your programme, writing all your appointments and other important things you have to do, dates when you should pay the bills and so on. But in time this device has become a lot more important, like an all-in-one device also used for playing games, listening to music and other fun activities. It is funny that it can now read any handwriting , the purpose that lead to its creation in the first place.

Of course there is a huge amount of Palm software on the internet, but I have found out the latest news regarding palm software directly from palminfocenter.com. This way I found out of a new and updated operating system about to be released for Palm Pixi - webOS 1.3.2. Not to mention the latest update performed by 2TwitMe, that is a full featured twitter client released by MetaViewSoft for Palm OS. @TwitMe supports all possible features just like the clients from more advanced platforms. Its users can perform automatic search, view profiles or simply chat or tweet. There is the option to run this application in the background and allow you to be notified when somebody sends you messages on Tweeter, it can capture pictures with the build-in camera and upload them directly on TwitPic . One of its most valuable features is that it can preview web links for you and you do not need to leave the application.



Talking about updates to older Palm software I must mention Astraware - My Little Tank game that came with a new version of the game compatible with Palm. The update consists of multi-language support, not of content or graphic or something like that. This game is already part of Palm games history and it won its share of fans from the Palm users .

Google maps is a very useful software you can use, not only on a Palm, but on any other device. However, you should know that the latest version of Google maps mobile, 2.0.2.0. cannot be supported by your palm. Try an earlier version and it will work just fine. I know  it is impossible to go on a trip without it to guide you all the way.

And since everybody loves free stuff, let me tell you a few things about the best free Palm software:

A5 and Today are applications allowing you to be reminded all the appointments you have on the current day and tasks that you have established for this day.



Pilot DB is a file data base with a strong set of features that works on many platforms at the same time. It also supports external memory data and import of files. PSMemo is also useful for making notes, remembering birthdays and other important dates; it is a replacement of the Palm Memo Pad that was built-in. eReader is an actual reader of e-books and allows your connection to world's online e-libraries ; it is a very important feature for students.Metro is a guide to public transport that has available data about the means of transport and their routes in over 200 major cities.

The list is, of course, much longer. But I offered you just a glimpse of what you can install on your lovely Palm in order to make it not only a fashionable, but also very useful device.
