Convert OGG to AIFF

The format is available without any restrictions. It was created in 2002 by programmers of The Xiphophorus Company and given its name after a character from Terry Pratchett’s “Small Gods”. The format is intended for multimedia playing and editing; sampling frequency is 6-192 kHz. It was designed for live streaming with an option to store some tracks with their own tags within the same file. When the file is opened in a player, all tracks show, which gives the appearance of music being opened from different files.

Originally, it was used for the entirety of OGG-using files, but for the recent ten years, it has being associated mainly with files of OGG Vorbis. The function set is the same as one of AC3 and AAC codecs, which leave the popular MP3 behind. The spread of OGG is restricted a bit due to the fact that it is not supplied by Apple products.

At its core, the extension is a container for several streams of audio, video and metadata. It generates the sound of a medium or high level within the range of 16-128 kbps/channel and exceeds MP3 by sound quality. In order to reduce the file size, the program deletes a certain amount of data, and therefore, the compression is irreversible. The format is best suited for storage of musical tracks, but it can be used as well for voice recording.

AIFF is intended for viewing and processing of audio data, as well as for its storage in digital devices. Apple designers developed it on the base of IFF in late 1980s. Thanks to lossless coding it is very similar to WAV. In Windows OS it is mostly used with .aiff extension.

AIFF files have gained great attention from Mac PC users. They are popular as well among professional musicians who are most particular about sound quality. The fact that the format is widely supported by various multimedia software, and universal players, may also be considered as a notable benefit. To open AIFF files in Windows OS it is required to install Apple iTunes, Windows Media Player, Roxio Creator, and some other programs.

When being coded, the stream is divided in sound segments. A minute of standard stereo sound corresponds with 10 Mb of memory, approximately. Standard non-compressed files use .aif or .aiff. In such files audio data are represented in the form of pulse code modulation. If some data are lost through codecs, .aifc is used.

A standard 16 bit AIFF file has 2 channels for stereo sound, and sampling frequency of 44 100 Hz. Being non-compressed, it differs in size significantly from MP3 and other similar formats. Sometimes it may contain samples and cycle information.
