Audio Apparatus and Method Therefor - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240244391 titled 'Audio Apparatus and Method Therefor
The patent application describes an audio apparatus that generates a flutter echo audio signal based on room metadata, such as room dimensions and acoustic reflection data.
- Receiver collects room metadata
- Estimator determines flutter echo estimate based on room metadata
- Signal generator creates flutter echo audio signal using feedback delay network
- Adapter adjusts parameters for feedback loops based on flutter echo estimate
Potential Applications: - Audio production studios - Live performance venues - Home entertainment systems
Problems Solved: - Enhancing audio quality in different room environments - Improving immersive sound experiences
Benefits: - Customized audio output based on room characteristics - Minimization of unwanted audio effects like flutter echo
Commercial Applications: Title: "Innovative Audio Technology for Enhanced Sound Quality" This technology can be used in various commercial settings such as recording studios, concert halls, and home theater systems to optimize audio performance and create a more immersive listening experience.
Prior Art: Prior art related to this technology may include patents or research on audio signal processing, room acoustics, and echo cancellation techniques.
Frequently Updated Research: Researchers may be exploring advancements in room acoustics modeling, adaptive signal processing algorithms, and real-time audio processing techniques to further improve the performance of audio systems in different environments.
Questions about the technology: 1. How does the adapter adjust parameters for feedback loops based on the flutter echo estimate? The adapter modifies the parameters of the feedback loops to optimize the generation of the flutter echo audio signal according to the estimated level of flutter echo in the room.
2. What are the key features of the signal generator in creating the flutter echo audio signal? The signal generator utilizes a feedback delay network with multiple feedback loops to generate the flutter echo audio signal from the audio source signal, enhancing the spatial audio experience.
Original Abstract Submitted
an audio apparatus for generating a flutter echo audio signal comprises a receiver () arranged to receive room metadata indicative of properties of a room. the room metadata may e.g. indicate dimensions of the room and/or acoustic reflection data for boundaries of the room. an estimator () determines a flutter echo estimate for the room in response to the room metadata where the flutter echo estimate is indicative of a level of a flutter echo in the room. a signal generator () includes a feedback delay network comprising a plurality of feedback loops. the signal generator () is arranged to generate the flutter echo audio signal from output signals of a set of feedback loops of the plurality of feedback loops being fed an audio source signal. an adapter () adapts a first parameter for a first feedback loop of the set of feedback loops in response to the flutter echo estimate.
