iamf-tools

What is IAMF?

The Immersive Audio Model and Formats (IAMF) standard is defined by the Alliance for Open Media (AOM).

What is 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.

Encoding IAMF content

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.

• IamfEncoderInterface API
• Command-line encoder for WAV or ADM-BWF files

Additionally, documentation is provided for third-party workflows. In particular these are useful for working with IAMF in MP4, and IAMF muxed with video.

• Merge IAMF files and video into an an MP4 file
• Encode WAV files to IAMF using ffmpeg

Decoding IAMF content

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:

• IamfDecoderInterface API
• Command-line decoder for standalone IAMF files

Web Demo

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.
