• AOMedia Open Audio Codec “OAC” Aims To Be The Successor To Opus While the Alliance For Open Media “AOMedia” is most known for developing the AV1 open video codec, the associated AV1 Image File Format (AVIF), and the next-generation AV2, they are now working on the Open Audio Codec (OAC). • I was tipped off this morning to the formation of the Open Audio Codec (OAC) becoming public this week. • The Open Audio Codec is based off the Opus audio codec and intended to be its successor. • This commit this week took to establishing the OAC project and based off the existing Opus codebase. • The new README file explains: Opus development was driven by Mozilla, Microsoft (particularly during the Skype days), and others – many of who are governing members of the Alliance For Open Media. • So far to the new OAC codebase there has been some tuning adjustments, renaming various symbols to using an “oaci_” prefix and other preparations for establishing the new Open Audio Codec project.
Article Summaries:
- AOMedia, known for the AV1 video codec, has announced the creation of the Open Audio Codec (OAC), a new project intended to succeed the Opus audio codec. The OAC codebase is derived from the existing Opus library, with early commits renaming symbols to an “oaci_” prefix and making tuning adjustments. A README on the public GitHub repository describes liboac as a reference implementation that will encode and decode raw OAC bitstreams, though the current tools include debugging data unsuitable for distribution. The initiative is in its infancy, but stakeholders can follow progress via the repository.
