Methods and apparatus for providing a distinct perceptual location for an audio source within an audio mixture
First Claim
1. A method for providing a distinct perceptual location for an audio source within an audio mixture, comprising:
- processing a foreground signal to provide a foreground perceptual angle for the foreground signal;
processing the foreground signal to provide a desired attenuation level for the foreground signal;
processing a background signal that has been low-pass filtered to provide a background perceptual angle for the background signal;
processing the background signal to provide a desired attenuation level for the background signal, wherein the background signal is processed to sound more diffuse than the foreground signal, wherein attenuation is applied to a first background channel based on a sampling rate of a delay line applied to a second background channel; and
combining the foreground signal and the background signal into an output audio source.

Abstract
In accordance with a method for providing a distinct perceptual location for an audio source within an audio mixture, a foreground signal may be processed to provide a foreground perceptual angle for the foreground signal. The foreground signal may also be processed to provide a desired attenuation level for the foreground signal. A background signal may be processed to provide a background perceptual angle for the background signal. The background signal may also be processed to provide a desired attenuation level for the background signal. The foreground signal and the background signal may be combined into an output audio source.
