Continuing the analogy with the graphical data, this format can be compared with the format bmp – as much information and very large sizes. One minute of audio from CD-quality format Raw pcm takes up about 10 megabytes. Even with today's hard disk drive for producers own Jukebox is a bit too much. Not surprisingly, the widespread popularity acquired audio compression format providing the coefficient compression of about 1:10 compared to Raw pcm at almost the same quality sound. These formats use compression algorithms to lossy audio. They can be compared with the graphic format jpg. Jpg file size is much smaller than similar bmp-file, but the image quality is somewhat worse (the more compression ratio – the worse the quality). Among the audio compression format with losses to date in the lead three: mp3, wma, and Ogg Vorbis.

The most popular format of course is an mp3. This format is supported by almost all software players for Windows, many players for Linux and countless hardware audio players and handheld computers. However, the mp3 is connected a problem that not everybody knows. Mp3 format patented. This means that any developer of software that uses a format mp3, must pay royalties. For this reason, many free programs that work with sound, do not support mp3.

He can be another way to apply in shape, consisting of the fact that the text, enclose it inside some kind of geometric shapes, usually correctly, that symmetrical both horizontally and vertically. Most popular of these figures are for an unknown reason the circle and ellipse, slightly less popular square and the 'sausage' (a rectangle with rounded at the ends of files that big angles). Are practically non-polygons angle of more than six. At first glance, the way primitive, but that they have used a fairly large world producers.

Incidentally, you can load the shape and meaning. So round and oval after adding for them parallels and meridians are beginning to resemble a globe and symbolizes the international relations or travel. A regular hexagon may well symbolize the bee products or cellular communication. Placing company name inside an asymmetrical shape, we automatically obtain an asymmetrical logo, ie logo, which has problems with composition. Most often this problem occurs when you try to use triangle, which will always distort the track.
