MP3 ABOUT

First appearance of standard digital music on the internet since 1995 which, in order to increase between one of the old standards did not look back. MP3 songs, because our favorite comfort, quality and availability of transportation brought unprecedented.

When you look into an MP3 collection, most MP3 sources you can see that the file-sharing sites. However, obtained from these sources can cause trouble MP3s. The reason for this to be different in sound quality. Unfortunately, users can do nothing about it. If you are lucky, you've downloaded to your computer may have been prepared in good quality MP3. Nevertheless, some of them can not be stolen should not forget how bad it is.

This is why choosing the legal and logical way to get CDs of your favorite singers, can be converted to MP3 and add it to your collection. This method, the quality of your MP3 collection to make sure the judge fully. iTunes, Windows Media Player and MusicMatch Jukebox software such as music CDs converted to MP3 songs at an event and are to be dismantled. But it's extremely important to the quality of those presets of this software may not find satisfying.

The best quality before you convert to MP3, MP3 Encoding, called the conversion process that will often come across 'bitrate', 'joint stereo' and 'VBR' need to know various parameters. Do not worry, it seems that this term is not hard to learn?

MP3 files made from a unique, first let's see what happens. The best way for it to compare with a music CD. Music CD, every track a specific resolution and frequency standard was created by the digital processing. CD music is recorded, sampling (sampling) is subjected to a process called. Essentially, the music, each with 16-bit digital value is divided into parts. 44.100 times per second by repeating it every two (right and left) is for audio channels. The resulting files are written to the CD will be brought together.

Music CDs with this method is prepared to make a file have to have a very large size. 5 minutes long, part of the approximately 50MB of hard disk space is occupied. Therefore, the high sound quality music CDs advantages, disadvantages of the files copied to a portable device or can also be large to be sent from the internet.

MP3 (MPEG-1 Layer 3) why it is popular. MP3 files are about one tenth the size of a music CD tracks to have. In terms of sound quality can not be said to be missing. Record every sound from MP3 in a blind manner as to create a large file, instead of the files with the help of predictive dialers to maintain sound quality and smaller size makes. Now let's see how this magic.

Fraunhofer Institute in Germany, a group of people to improve the standard MP3, first heard of people doing work on the perception of the sound began. Complex human talent and a fantastic sense of what is to detect sounds in the outside world has its own characteristics. For example, a train station, train station, you call your friend when your friend does not hear it. Why? When you hear two voices, because the human ear can detect high and low is what one does not care. This behavior, constitute the core of the MP3 encoder software. For example in front of a loud guitar sound, a voice in the back are the whisper level, the software convert it to MP3 sound, never heard by the human ear can not be eliminated as will the raucous sound. When creating MP3 files, MP3 encoder software examines the content of the songs and background sounds can be heard whether their control. Depending on the results, some noise is eliminated. That the minimum size of MP3 files that will play a major role. In addition, while maintaining the quality of the MP3 standard used to reduce the file size is also available another trick. MP3 files do you think they are truly in stereo? Joint Stereo (JS) by using a system with MP3, here's the cunning of the shadow and pressing the low frequency, ie people accordance detected that could not sound in the low-frequency stereo signal by combining mono the single-channel signal makes.

The human ear can detect is in the middle and high frequency sounds, JS Encode system on a different function, each is looking for similarities between the two channels. When you listen to the left and right audio channels, in fact, notice that the sound is very similar. In a small number of sounds (percussion, vocals, etc..), These two channels may vary.

Stereo, turn the channel separately, while the MP3, Joint Stereo covered a lot more to reduce to practice a different method. Medium volume (L + R) and side (left-right) is split in the form of channels. According to this separate stereo channels allowing you to provide a better compression. While listening to MP3 software such as Winamp or iTunes, this channel is divided into left and right again into being normal.

MP3 converters one last time before you create the file using the conventional data compression algorithms are brought together in one. This is known as Huffman compression system. The most important feature of the Huffman lossless compression technique (losless) is that, when no data compression that does not blow.

This repetitive compression system compresses data in a successful way. In digital data files created from scratch, and they figure, Huffman compression process at the end of MP3 files in considerable savings. A common application of these standards, such as WinZip, and is also used in standard JPEG digital photos should be noted.


Convert music from CDs to MP3 with the song also makes removal of the popular Let's look at the applications.

dbpowerAMP
Free, small and efficient, this tool makes a very simple MP3 creation. Effect, which is one of the most powerful MP3 converter LAME MP3 conversion algorithm (see box MP3 jargon) owed to the method used.

Also very simple interface. After inserting the CD, a toolbar appears on the main screen. Here you want to convert songs from CD to MP3 Rip can begin by choosing. Also, if you have Internet access, the software should automatically access the database CDDB MP3 albums to be removed from the CD, will enter information such as artist name.

This is a small, free and very powerful toolthat makes very simple MP3 creation. Ituses the LAME MP3 encoding engine (seeJargon box), which is one of the highestquality MP3 Encoders.

Toolbar, the "rip" button in MP3 or WAV format to make disassembly begins. Menu "Compression settings" option, bit rate, channel, dial-type (Select Joint Stereo) and sampling frequency (44.100 's leave) serves to adjust. Slide the slider bar to flip the bit rate can be adjusted. High quality and are looking for a quality not much space you can choose up to 160 Kbps.

"Advanced options" option in the LAME converter gives you access to the more advanced options. Conversion be based on the fixed or variable can be set here. To simplify business, it is possible to use different available options. When you're done "OK" to return to the main window by clicking here and here, "rip" the head of the operation. MP3 files will be ready after a while!

iTunes
ITunes if you still have not used you must use. And a great free MP3 player / organizer addition to being, by removing the songs from CDs to MP3 music converting said.

"Edit | Preferences" option, and click "Importing" tab, click on. "Import Using ..." in the category "MP3 Encoder" to select the converter. Here "Custom ..." option when you stereo, bit rate, sampling frequency, channel stereo mode conversion techniques and is coming to a screen can be specified. The bottom two options were expecting a higher quality translation technique can work for you. Therefore, it is useful to keep the options selected.

When you get used to the interface, MP3 and turn technique changing the parameters of speed, quality according to different needs, such as MP3 files can create.

Easy CD-DA Extractor
This software was prepared in December 1997, ripping songs from a CD perhaps the first software that can do the job. Therefore, MP4, hair, AAC, Ogg Vorbis and Windows Media Audio formats supported, such as very natural. Poikosoft major scratches on the manufacturer of the software and copy protection can not be removed says the songs on CDs.



After studying music CD to freedb web site (freedb.org> Home) to connect to retrieve the song titles. If you are not connected to the internet and copying, they will have song titles Track 1, Track 2, etc.. will be in the form.

Software ID3, ID3v2 (see Jargon box) such as the meta data formats are supported. Apart from removal of the different functions are also available. In a format that can convert audio files into another format. You can also write CD. Transfer music CDs to the hard disk so that after the songs, love songs, which you can create a compilation CD.

Easy CD-DA Extractor'ın also a plus point to get the best sound quality LAME MP3 VBRencoding addition to the technique used. CD of music written and often self-other capabilities of the software will still wondering. CD-Text,. Cue formats, as with buffer underrun protection to provide accurate and hassle-free CD burning. So suddenly the CD an error message when writing CD burning will not learn. Buffer Underrun the course for this feature to your hardware needs.

CD Text album, artist and song information such as name of the music makes CD storage. This information does not affect the normal capacity. MP3s Cue the title, artist name, time and position information, such as a CD store on a simple text file.

INFORMATION
Hundreds of software has to be able to create MP3 files. Most of these removal / conversion is done. This means that the music is from CDs and MP3 files stored on your PC by converting are made. This software is MP3 sound quality and file size in the process of creation, the important criteria that may affect the degree of the owners. Stock options are not sufficient, you learn what you can do about it means that your time has come. If you have information about the following parameters, you can set advanced settings by making quality MP3s.

Bit rate (a rate)
Has a simple rule, the number of bits increases, the quality is increasing. This value is translated into a second number of bits in the voice says. Converted at a rate of 128 Kbps for a minute of an MP3 file, create a file size is 2.81MB. You can calculate it as follows:

128 Kbits / sec x 180 kilobits per second = 23.040
(23.040 kilobits / 8) x 1024 = 2.81 Mbytes

When you increase the bit rate needs to increase the quality. Your mind, but do not remove the file size has increased.

With a rate of 128 Kbps MP3 up to you to create a reasonable sound quality. However, a rate as high as 160 Kbps and does not occupy much space on the disk, as well as more appropriate to the original sound quality. If you want to rate up to 320 Kbps, but this money is used only to libraries and will be useless in everyday use to create MP3 files are large.

Frequency (Frequency)
Determines the number of samples per second. Every second CD is the sound that analog signal and converts it into digital signals. This high value means that the high quality sound. For example, the standard music CDs to 44.1 kHz frequency. In particular the need to change this value if needed. Sampling frequency is not only high-frequency sounds such as speech and making recordings you can reduce cases.

Dialing (Encoding)
MP3 files can be created using two translation method: constant bit rate (CBR) or variable bit rate (VBR). As the name implies in the first method, the bit rate is kept constant throughout the entire song, but in the other bit rate compared to MP3 Converter is changing the sound characteristics. For example, played a part in one of several instruments, such as requiring a higher bit rate where the value is increasing, in a quieter part of the bit rate is reduced. This is the translated files with VBR provides less space.

LAME MP3 conversion (LAME MP3 Encoding)
LAME MP3 Converter today as one of the best are accepted. The LAME still continue to be developed, an algorithm based on the quality and speed dial. LAME v3.89 For example, the average bit rate from 192 Kbps to 1 minute 20 seconds in a song can convert to MP3.

Channels
Mono and stereo standards are known to everyone. Channel cycle time in two channel stereo and turns separately. However, Joint Stereo (JS) with a method called instead of the left and right channels as well as medium and leaves. The reason for this by bringing together similar sounds better compression. While religion is the right and left again divided as it sounds, so not a problem during playback.

ID3 tags (ID3 Tags)
MP3 files on one of the best singer or group as well, the song name, date, album, etc.. able contains the information. This is called ID3 tags on the way to go in terms of use. Most of the MP3 player that supports this, so you have information about the song can be hasty.

Freedb
ID3 tags are in order to obtain a free kullanabileceğ the freedb database, every music CD is a unique identification number as set out in a lot of information is gathered within. Therefore, while music CD into MP3, software and freedb'ye says that the identification number is required to access information ..
