SELECTIVE MODIFICATION OF STEREO OR SPATIAL AUDIO - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240056734 titled 'SELECTIVE MODIFICATION OF STEREO OR SPATIAL AUDIO
Simplified Explanation
The patent application describes an apparatus, method, and computer program for providing a modified stereo or spatial audio signal by detecting and reducing unwanted noise in individual signals from microphones of a user device. The modified audio signal is then outputted through one or more speakers.
- The invention involves providing a stereo or spatial audio signal that represents an audio scene using individual signals from microphones of a user device.
- Unwanted noise in at least one of the individual signals is detected.
- Based on the determined level of spatial interest in the audio scene meeting a predetermined condition, the stereo or spatial audio signal is modified.
- The modified audio signal is then outputted through one or more speakers.
Potential Applications:
- Enhancing audio quality in video conferencing or telecommunication systems by reducing background noise.
- Improving the audio experience in virtual reality or augmented reality applications by minimizing unwanted noise.
- Enhancing audio recordings in professional or consumer-grade recording devices by reducing ambient noise.
Problems Solved:
- Reduces unwanted noise in audio signals, improving the overall audio quality.
- Provides a more immersive and clear audio experience by minimizing background noise.
- Enables better communication and understanding in audio-based applications by reducing interference from unwanted noise.
Benefits:
- Improved audio quality and clarity in various applications.
- Enhanced user experience in virtual reality, augmented reality, and telecommunication systems.
- Increased productivity and efficiency in audio recording and communication tasks.
Original Abstract Submitted
an apparatus, method and computer program is described comprising: providing a stereo or spatial audio signal produced using individual signals from respective microphones of a user device, the stereo or spatial audio signal representing an audio scene; detecting unwanted noise in at least one of the individual signals; responsive to detecting the unwanted noise, modifying the stereo or spatial audio signal based on a determined level of spatial interest in the audio scene meeting a predetermined condition; and providing the modified audio signal for output via one or more speakers.
