ADJUSTMENT OF REVERBERATION LEVEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18401012 titled 'ADJUSTMENT OF REVERBERATION LEVEL

Simplified Explanation

The method described in the patent application involves adjusting the audio signal of a source based on its directivity pattern and a reverberation parameter to achieve a target energy ratio with respect to the reverberant sound component. Here are some key points to note:

• The method involves receiving an input audio signal and a reverberation parameter.
• It also involves obtaining the directivity pattern of the audio source and deriving a relative gain based on this pattern.
• The relative gain is used to adjust the audio signal to meet the target energy ratio.
• The adjusted audio signal is generated using the input audio signal, reverberation parameter, and derived relative gain.

Potential Applications

This technology could be applied in audio processing systems for live performances, recording studios, and virtual reality applications where realistic audio rendering is crucial.

Problems Solved

This method helps in enhancing the spatial audio experience by adjusting the audio signal based on the directivity pattern of the source, resulting in a more immersive and realistic sound environment.

Benefits

Original Abstract Submitted

A method of rendering an audio source is provided. The method comprises receiving an input audio signal corresponding to the audio source and receiving a reverberation parameter indicating a target energy ratio with respect to a reverberant sound component of audio for the audio source. The method further comprises obtaining a directivity pattern of the audio source, deriving a relative gain for the audio source based on the obtained directivity pattern, wherein the relative gain is relative to an omnidirectional audio source, and generating an adjusted audio signal using the received input audio signal, the reverberation parameter, and the derived relative gain.
