A free and open digital multimedia container file format maintained by the Xiph.Org Foundation. The format was designed to provide efficient streaming and manipulation of digital multimedia. Its name is derived from “ogging,” a term from the computer game Netrek, referencing the high processing cost of early versions of the software.
Key Features
Ogg Vorbis supports the multiplexing of multiple independent streams for audio, video, text (such as subtitles), and metadata. The format is unrestricted by software patents and is widely used for encoding and compressing audio files while maintaining high audio quality and smaller file sizes compared to formats like MP3.
- Audio Compression: Ogg Vorbis is commonly used for lossy audio compression, making it ideal for streaming audio online.
- Video Support: The Ogg container format supports video through the Theora lossy video layer.
- Metadata and Text: The format can also include text streams for subtitles and metadata.
Common Use Cases
Ogg Vorbis is often used for streaming audio online, making it relevant to online technology and potentially to sales and marketing efforts involving audio content. The format’s efficiency and high audio quality make it a popular choice for digital audio applications.
File Extensions
Until 2007, the .ogg filename extension was used for all files whose content used the Ogg container format. Since then, the Xiph.Org Foundation recommends using specific extensions for different types of content, such as .ogv for video and .oga for audio.
