    The Immersive Audio Model and Format

    In 2020, Samsung and Google worked together to develop the Immersive Audio Model and Format (IAMF), an audio technology that processes sound data in order to generate immersive experiences. IAMF integrates customizable spatial audio and capabilities with AI-based scene analysis for creating vertical sounds. This allows users to experience optimal sound quality across various home audio setups without changing the original format of audio data in their models.

    The new release marks a milestone moment for all sorts of audio possibilities, setting up its own unique benchmark when it comes to providing captivating 3D auditory journeys beyond the traditional left and right stereo channels. The best part: it is open source and more accessible than the competition.

    Key Components of IAMF Technology

    IAMF technology combines three features to create a supreme sound experience that is customizable according to user preferences and environment:

    • AI-driven scene analysis,
    • audio customization capabilities, and
    • vertical sound.

    This advanced solution makes it possible for any home audio device – including gaming consoles, mobile devices, home theater systems or even a simple Sound Bar – to enjoy the ultimate listening and playback experience.

    Customizable Audio

    Using IAMF’s customizable audio feature, users have the opportunity to hear a more immersive and tailored sound experience. They can fine-tune their 3D audio by adjusting dialogue, background, character dialogue, music and other audio data in individual layers independently to set desired volume settings for various mix configurations.

    This provides playback listeners with an enhanced level of control over their tracks as they can accurately adjust specific elements within them according to how they wish them to be heard. By using this technology one could listen differently when watching sports. Isolating the game soundtrack from the commentary track while having access alters both volumes individually depending on what is being focused upon the mainstream audience at any given time!

    IAMF offers multiple options that give people greater choice when dealing with intellectual material thus making sure of optimal usage of its functionality. From separating sounds between two headphones up until tinkering around levels subtly an audio track. The possibilities are endless thanks only to these technological advances which allow us to collectively extend our reach ever further into hearing than before!

    Frequently Asked Questions how IAMF makes sound

    What are immersive audio formats?

    Immersive audio formats such as Dolby Atmos, DTS, Auro 3D, and Sony 360 Reality Audio provide users with a realistic sound experience in order to create an immersive listening atmosphere. Such technologies are all based on different technical standards but result in the same effect of enhanced sonic immersion.

    What is the IAMF format?

    AOMedia provides IAMF, a royalty-free audio container specification along with an open-source reference software decoder that can be accessed on its GitHub platform.

    How does immersive audio work?

    Immersive audio gives a more full, intense sound as it makes the sound bars the music audible beyond just left and right stereo, recreating how the artist meant to hear audio be heard.

    What is the difference between spatial audio and immersive audio?

    Spatial audio provides an engrossing 360-degree soundscape allowing listeners, giving the impression that noise is coming from any direction as in a real musical performance. On the other hand, immersive audio does not possess this feature. It focuses on the sound bars providing robustness and clarity to existing sounds rather than creating virtual environments with them. Both these forms of sound manipulation render auditory experiences unequaled in quality and realism for listeners’ utmost satisfaction.

    How does customizable audio in IAMF work?

    Customizable audio is a feature provided by IAMF that enables users to alter the 3D soundscape according to their preferences with adjustable layers such as dialogue and music in the background of action scene or certain scenes.

    What is AOMedia?

    The Alliance for Open Media (AOMedia) stands as a collaborative consortium that focuses on advancing media technology by developing open-source, royalty-free compression standards and formats. What sets AOMedia apart from its competitors lies in its commitment to fostering innovation while prioritizing openness and accessibility.

    What is EAR?

    The Ear Production Suite encompasses the Audio Definition Model (ADM) and introduces a specialized binaural renderer designed to enable the creation and reproduction of object- and scene-based audio programs. While ADM provides a standardized method for loudspeaker reproduction, headphone reproduction lacks a standardized approach.

    The suite’s binaural renderer utilizes virtual loudspeaker rendering with windowed binaural room impulse responses (BRIRs) for object rendering, replacing delays in BRIRs with variable fractional delay lines per ear and object to mitigate comb-filtering effects. For diffuse sources, original delays in BRIRs are utilized to create a perceived extent.

    To manage loudness changes between neighboring loudspeaker BRIRs, the system dynamically adjusts each source’s overall gain. This open-source C++ library, integrated into the VISR framework, allows real-time head-tracked binaural output, enhancing immersive audio experiences and serving as an integral component within the EAR Production Suite for advanced audio production and reproduction purposes.https://ear-production-suite.ebu.io/
