Immersive Audio Model and Formats

IAMF is a royalty-free multicontainer specification developed by Aomedia with the goal of providing a modern audio codec with enhanced audio experiences. It is designed to be adaptable to the latest audio codec technologies. The IAMF specification was developed through a collaborative effort between Samsung and Aomedia. Samsung initially proposed the idea of a new audio codec specification. It can be used to embed payload. It contains OBU with an ISO specification (to be added,,,

It's not really, it's a bunch of things, it defines a couple OBU. One that is designed to denote how to mix audio elements into a single "Immersive audio signal" (3d audio), a parameter OBU that denotes the specifics of the previous audio OBU (duration, gain etc.).

It denotes the IA sequence (the order of OBUs and whatnot) and how to encapsulate it in an ISO-BMFF container, so MP4, M4A etc. of the supported codecs. It supports Opus, AAC, FLAC, and PCM (needs to be added,,,

The specification is written in a markup language called Markdown. Markdown is a simple and easy-to-read language that uses plain text to format documents. This makes the specification easy to read and understand, even for people who are not familiar with markup languages.

The specification is also organized in a way that makes it easy to find the information you need. It is divided into chapters and sections, with each chapter covering a different topic. This makes it easy to find the information you need without having to read the entire specification.

Here are some of the key features of the IAMF specification:

• It supports a wide range of immersive audio formats, including binaural audio, ambisonic audio, and spatial audio.
• It provides a detailed description of how to encode and decode immersive audio content.
• It includes examples of how to use the IAMF specification to create immersive audio content.

The IAMF specification is a valuable resource for anyone who wants to create immersive audio content. It is easy to understand and use, and it provides everything you need to get started.
