The patent application (Publication Number: US20240040317A1) describes an apparatus and method for processing audio signals to generate spatial audio signals. The apparatus includes at least one processor and memory storing instructions to obtain multiple audio signals, determine noise levels in the signals, calculate spatial audio parameters based on the noise amount, process the audio signals accordingly, and generate spatial audio signals. The determination of spatial audio parameters is dependent on the noise level, with different processes for noise levels above or below a threshold.

Furthermore, the apparatus can estimate spatial audio parameters such as direction and diffuseness based on the noise level, using predetermined values or recent estimations as needed. The method involves obtaining audio signals, determining noise levels, calculating spatial audio parameters based on noise amount, processing the signals, and generating spatial audio signals. The process for determining spatial audio parameters includes estimating direction parameters and using angular differences for second parameters based on noise levels falling within specific thresholds. This innovation aims to enhance the quality of spatial audio processing by adapting to varying noise levels and optimizing the generation of spatial audio signals for improved user experience.
