What is IAMF?

Immersive Audio Model and Formats (IAMF), the organization's first-ever audio container specification offered under AOMedia’s royalty-free license, and its open source reference software decoder, complete with test streams, are readily accessible on AOMedia’s GitHub.

IAMF provides creators with the tools to craft immersive audio experiences across a myriad of applications, from streaming and gaming to augmented reality and virtual reality, as well as traditional broadcasting.

IAMF’s ability to carry and include multiple audio mix configurations enables creator and user controllable loudness adjustments for different playback preferences. IAMF offers seamless delivery of both channel-based and scene-based ambisonics spatial audio presentations to a wide range of devices, including headphones, mobile phones, televisions, soundbars and home theater systems.

IAMF provides means to signal rendering algorithms, such as EAR and BEAR, for playback in loudspeaker layouts and headphones. Thanks to existing open source plugins like the EAR Production Suite, which includes IAMF guidelines-compliant renderers for multi-speaker layouts and binaural monitoring, creators can dive into immersive audio content creation and sound mixing.
