Ogg is a project to create an open source, patent-free multimedia system. It was created by the Xiph.org Foundation.

Currently, the project includes several specifications:

• the Ogg bitstream format, which can encapsulate arbitrary audio/video streams and acts as a container
• Vorbis, a general-purpose audio codec
• Theora, a video codec which is still in the alpha stage of development
• FLAC, a lossless audio codec
• Speex, an audio codec designed for speech
