In What Year Did Active Development on Vorbis Begin?

Active development on the Vorbis project began in 1998, sparked by impending patent royalty demands surrounding the widely used MP3 audio format. Created by Chris Montgomery and developed under the Xiphophorus company (now the Xiph.Org Foundation), Vorbis emerged as a patent-free, open-source audio compression format designed to ensure unrestricted multimedia encoding and streaming.

Origins and the 1998 Catalyst

While Chris Montgomery had been experimenting with general audio compression algorithms as early as 1993, focused development on Vorbis specifically commenced in September 1998. In that month, the Fraunhofer Society announced plans to actively enforce patent licensing fees on software developers producing MP3 encoders and decoders.

Recognizing that patent restrictions posed a serious risk to free and open-source software, Montgomery launched the Vorbis initiative as part of the broader Ogg multimedia project. The objective was clear: engineer a modern, high-quality audio codec from scratch that avoided infringing on existing audio patents.

Timeline to Standardization

Following the ramp-up of development in late 1998, an expanding community of open-source contributors joined Montgomery to refine the codebase.

• May 2000: The Vorbis file format specification was officially frozen for version 1.0, establishing a baseline bitstream standard.
• 2001: To maximize adoption across both commercial and open-source ecosystems, the project transitioned its licensing model from the LGPL to a permissive BSD-style license.
• July 19, 2002: The Xiph.Org Foundation issued the stable 1.0 release of the reference library (libvorbis), cementing Vorbis as a premier royalty-free alternative to MP3 and AAC.

The project's launch in 1998 paved the way for open multimedia standards, eventually influencing subsequent formats such as Opus and WebM.
