Handling of Medium Absorption in Audio Rendering

原文（中文）

A method of rendering an audio source () for a listener (). An audio renderer () determines a listening distance () that comprises a distance from which the listener () listens to the audio source (). The audio renderer () determines a recording distance () that indicates a distance from which an audio signal () for the audio source () was recorded. The audio renderer () renders the audio source () based on the listening distance () and the recording distance (). The audio renderer () for example calculates medium absorption gain value(s) () and applies the medium absorption gain value(s) () to the audio signal (). For example, on a logarithmic (dB) scale, each medium absorption gain value () may be positive if the listening distance () is less than the recording distance () or negative if the listening distance () is greater than the recording distance ().
