Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a rendering apparatus and technique for audio scenes that dynamically adapts audio output based on specific user or environmental contexts. The system includes a contextualization unit that collects or derives context-specific data (such as hearing profiles, position, or background noise) and generates rules or parameters to guide an audio rendering unit. The rendered audio output is customized — for example, enhancing intelligibility for users with hearing impairments, personalizing spatial audio according to user movement, or optimizing playback for particular environments like vehicles or noisy locations. This approach enables real-time, on-the-fly adaptation of audio rendering without requiring separate manual adjustments or re-authoring of audio content.

Use CasesContent extracted from patent full text and abstract with AI.

  • Personalized audio rendering in virtual reality (VR) or augmented reality (AR) environments for users with hearing impairments.
  • Adaptive in-car audio systems that adjust sound presentation based on vehicle and passenger location, orientation, or environmental noise.
  • Gaming platforms that modify spatial audio based on player's hearing profile, avatar orientation, or gameplay context.
  • Broadcast or streaming applications that make dialogue or important sounds clearer for individuals with reduced hearing or cognitive sensitivity.
  • Smart home or public announcement systems that optimize audio delivery based on background noise and user preferences.
  • Assistive devices or hearing aids that benefit from device-side audio scene adaptation without extra processing latency.

BenefitsContent extracted from patent full text and abstract with AI.

  • Improved audio accessibility and inclusivity for people with various forms of hearing loss or cognitive differences.
  • On-the-fly, real-time adaptation of audio output to fit individual user needs and specific environmental conditions.
  • Lower processing latency and reduced power usage compared to traditional hearing aid post-processing, as adaptation occurs during rendering.
  • Flexibility to apply context-based audio modifications such as filtering background noise, amplifying certain directions, or simplifying complex soundscapes.
  • Ability to integrate personalization and context-awareness in diverse scenarios (home, vehicle, entertainment, VR/AR) without extra burden on content creators.
  • Enables advanced interactive audio features such as dynamic focus zones, smart audio culling, and context-dependent spatialization.

Patent Abstract

There is disclosed renderer apparatus (400), comprising: a rendering unit (430) configured to process an audio scene representation (402, 412) to be rendered and to receive at least one context-specific rule or parameter (441, 442), the rendering unit (430) being configured to generate a rendered audio signal (422) from the audio scene representation (402, 412) conditioned by the at least one context-specific rule or parameter (441, 442), a contextualization unit (440) configured to receive and/or derive context-specific data (461, 462), the contextualization unit (440) being configured to provide the at least one context-specific rule or parameter (441, 442) to the rendering unit (430) based on the context-specific data (461, 462).
