Speed-up mixed order mono-coded ambisonics (~2.47x for horizontal 3OA). - Precompute a gain matrix without the empty channels for mono-coded ambisonics. - Results in a smaller matrix to be used for rows that otherwise would have been zeroed out. PiperOrigin-RevId: 922126133
The Immersive Audio Model and Formats (IAMF) standard is defined by the Alliance for Open Media (AOM).
iamf-tools?iamf-tools implements tools to help users process and work with the IAMF format. These tools can be used as a complement to the libiamf reference decoder and other tools such as ffmpeg and MP4Box.
There are multiple workflows for creating IAMF content, supporting different types of input or output.
iamf-tools provides a few ways to encode IAMF content.
Additionally, documentation is provided for third-party workflows. In particular these are useful for working with IAMF in MP4, and IAMF muxed with video.
The libiamf reference decoder and its documentation are available at https://github.com/AOMediaCodec/libiamf/. It provides decoding tools for standalone IAMF and IAMF in MP4.
iamf-tools provides a different implementation and command-line decoder:
The web demo hosted in the GitHub Pages of this repo decodes and renders standalone IAMF files to stereo and binaural WAV files for preview and comparison.
