Convert OGA to OGG

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.
