What is OGG file?
Ogg Vorbis is a new audio compression format. It is roughly comparable to other formats used to store and play digital music, such as MP3, VQF, AAC, and other digital audio formats. It is different from these other formats because it is completely free, open, and unpatented.
The ogg file format is an open standard container format used to provide more efficient streaming and higher quality presentation. It is typically used to encode content found freely available on the Internet to improve the streaming quality of the content. The Xiph.Org Foundation put together the specifications for the open standard hoping to create a patent free method for encoding media. When using the ogg file format, a decent sampling rate is around 96kbits, a 96kbit ogg file is comparable to a 160kbit MP3 file. The compression is much better, allowing smaller file sizes and better quality files.
