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/back to the blog
