What Is The Bitrate? What You Should Know About It.

With the term “bitrate” we face at the mention of audio and video formats. To understand this term, you must master the process of compressing and encoding files. German scientists have laid the general principle of file compression with minimal loss. On the example of coding the original MP3 sound file is cut into fragments, the duration of 50 milliseconds, each of which is analyzed separately. In the analysis of the fragment is decomposed into harmonics of the Fourier method, of which, in accordance with the theory of sound perception by the human ear thrown those harmonics that people perceive worse than the rest. These are quieter harmonics on the back of the higher ones. As a result, emitted sounds are masked due to the inertia of hearing. The information about the harmonics left after filtering and recorded in the MP3 file, which results in a much smaller than the original WAV.

WAV-file contains detailed information about the original sound, digitized and quantized with a frequency of 44kHz. This information is stored on ordinary audio-CD. When playing there is the inverse transformation, in which the remaining harmonic is re-converted into sound waves. Some of the information about the original signal was lost, because the sound is not identical to the original. But throwing irrelevant sounds, so the human ear cannot distinguish the signal from the original order, which was packed to MP3.

Bitrate is the amount of information per unit time. Its essence – how much information about every second of recording we can spend. Naturally, as it is smaller, the smaller the size of the files have the same length of time, thus will have to throw more “extra” harmonics. Bitrates are units of measurement – kilobits per second (Kbps) and megabits per second (Mbps). MP3 audio compression algorithm is often used with 128 kbps compression. They are of two types: fixed and variable. For example, when a video compression is used with a constant bitrate a fixed amount of data is used to encode a second film. In the case of variable bitrate the codec installs eigenvalue bitrate depending on the scenes of the movie. For example, when encoding to mpeg the gain in compression is mostly obtained by retaining only the difference between adjacent frames. During a slow scene change the difference between frames is small and thus can reduce the amount of a bit rate required for playback of these scenes. However, with the abrupt change of scenes in the film, the differences in staffing increase dramatically in size and require more bitrate to play such scenes. In contrast to the constant bit rate, at a variable one cannot predict the size of the output file, it depends on the ratio of “fast” and “slow” scenes in the film.

Regarding to radio online, the downloadable sound quality of radio stations with the network also can be analyzed by bitrate. The choice between 48kbps and 128 kbps bit rate, I hope, will introduce you to a long meditation.

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

We would like to give you a final piece of advice – today the web technologies give you a truly unique chance to choose what you need at the best terms which are available on the market. Funny, but most of the people don’t use this chance. In real life it means that you must use all the tools of today to get the information that you need.

Kill Unresponsive Apps: Super F4 Hotkey

Windows only
It’s always annoying when a program becomes unresponsive where you have to pull up the Task Manager to kill it, but it can be even worse when some of the fullscreen games start to freeze. That’s how one developer felt, and so they decided to do something about it.

SuperF4 creates a keyboard shortcut (Ctrl+Alt+F4) that will forcefully close any foreground program, including fullscreen games. Why is this so annoying with games? Well some games prevent you from using shortcuts (chiefly Ctrl+Alt+Delete) when in fullscreen mode. That can be extremely painful since the only action you may be able to take is to shutdown your computer by holding the power button, which is generally a last resort for most of us.

The app also has a secondary mode that is accessed by pressing Win+F4 keys. Your mouse cursor will become a skull, and all you have to do is select the window/program on the screen that you’d like to kill. It sure beats digging through the Task Manager!

Test Your Boot Time

        You know when someone tells you their computer takes 20-minutes to boot up, and you roll your eyes because you know they are just exaggerating. Well, there is a way to find out. All you have to do is install BootRacer on their machine, and then restart it. The application will keep an eye on certain events such as how long it took the user to login and how long it took for their desktop to finish loading, and it will report back.
One of the cool things is that BootRacer actually displays a window in the lower-right corner of the screen after you’ve logged in showing how long it has taken to startup thus far. It will continue incrementing the timer until all the startup apps have finished loading, and will alert you once it has completed.
Here’s a rundown on some of the features pointed out by the developer:

• Automatically calculates your Windows boot time.
• BootRacer uses minimum of computer resources.
• Runs under the non-administrator accounts.
• BootRacer logs all the results to the history report and to standard event log. You can check events using Windows Event Viewer.

The history report feature may not seem all that useful, but with it you may be able to pinpoint when some sort of change was made to the machine that significantly slowed it down. You might even be able to salvage some time by simply rolling the computer back to a restore point before the slow-down occurred.
BootRacer is free for non-commercial use, and can be helpful when fixing someone’s computer. If you run it before and after the optimizations you’ll actually be able to give them real-world numbers as to how much faster their computer is thanks to your magical tweaks.

Linkin Park Logo Start Menu Button (Windows 7 only)

Here's a screenshot:

It has a nice hover/clicked state too.

For the people who want it too, here's a simple tutorial.
It isn't hard and you can always change it back  (I'm not responsible if it causes any problems though, of which the chance is minimal)

Avoiding HF RS Premium File Sharing Accounts turning FREE/Invalid

Ever wonder why Premiums posted in this site easily get downgraded to Free account or invalid password without someone ever changing its credentials?

Well, thats because its your fault.

RS and HF all has IP Tracer Capability embedded to their site. Everytime that a certain account is logged more than 2 IP(internet Protocol) simultaneously the account is immediate downgraded to FREE ACCOUNT or INVALID PASSWORD which the new password is to be send to the bonafide owner's email.
