Though MP3 is the most popular format for encryption music, it is by no means the only one. There are two basic methods for compression audio – lossless and lossy, and for each of these methods there are galore formats.
Lossless compression means that none of the audio data is removed during compression. Lossy compression means that audio data is for good
removed from the audio file. Lossy compression results in smaller files, but there is no way to reconstruct the audio data to its innovational format. MP3 is an example of lossy compression.
Lossy Compression Formats
There are galore alternatives to MP3 once
it comes to encryption audio files. Microsoft reportedly developed the WMA format to avoid the licensing price associated with MP3. WMA files can be compete with the Windows Media Player that is enclosed
with the Windows operational system as well as galore another audio players. It features similar encryption rates to MP3 and similar file sizes.
AAC (Advanced Audio Coding) is the format preferred by Apple and is used for its popular iTunes and iPod products. AAC files can be smaller than MP3 files because it uses much efficient encryption technology. A 96 kpbs AAC file is similar in sound quality to a 128 kbps MP3 file.
Ogg Vorbis is another type of lossy compression and uses .OGG as the file extension. It is an open-source product and unlike MP3, there are no patent restrictions on its use.
Lossless Compression
For the audio pedant who insists on the better quality sound possible, lossless compression offers CD quality sound. The tradeoff is larger files sizes – piece MP3 can compress audio in the range of 80% - 90%, lossless compression typically compresses the file by half.
Popular lossless formats include FLAC, Monkey’s Audio, and SHN (Shorten). These formats are supported by galore audio players and are popular for archiving CD collections as well as for commerce music.
