Alternatives to MP3

Although MP3 is the most popular format for encoding music, is far from alone. There are two basic methods to compress the sound? without loss and defeat, and for each of these approaches is that many formats. Without loss of compression means that no audio data is removed during compression. With the loss of audio-compression means that data are permanently removed from audio files. With the loss of compression results in smaller files, but it is not possible to reconstruct the audio data in its original format. MP3 is an example of lossy compression. Lossy compression formats, there are many options when it comes to MP3 encoded audio files. Microsoft has developed the WMA licensing in order to avoid the costs associated with MP3. WMA files can be played with Windows Media Player included with the Windows operating system, as well as many other audio players. It has similar prices for MP3 encoding and even the size of files. AAC (Advanced Audio Coding) is preferred by Apple and is used for its popular iTunes and iPod. AAC files can be less than MP3 files, increasingly use encryption. A 96 kpbs AAC file is similar to good quality at 128 kbps MP3 file. Ogg Vorbis is another type of compression and loss of use. Ogg that type. It is an open source products, and unlike MP3, there are no patent restrictions on use. Without loss of audio compression for the purists who insist on the best possible sound quality, without loss of compression CD-quality sound. The flap is higher file sizes? while MP3 can compress the sound up to 80% - 90% without loss of compression normally compress the file by half. People without loss formats Flac, Monkey's Audio, and SHN (reduce). These formats are supported by many audio players and are very popular for archiving collections of CDs, as well as to manage music.
