Psycho-acoustic noise suppression
First Claim
1. A method comprising:
- determining a direction of the ambient noise in an environment of a listener;
receiving an audio signal, wherein the audio signal represents a remote talker'"'"'s voice;
generating a first copy of the audio signal;
generating a second copy of the audio signal;
introducing a time delay into the first copy of the audio signal, wherein a magnitude of the time delay is based on the direction of the ambient noise;
providing the first copy to a first ear of the listener subsequent to introducing the time delay; and
providing the second copy to a second ear of the listener subsequent to introducing the time delay.

Abstract
A method for perceptual enhancement of a received remote talker'"'"'s voice, in the presence of local ambient noise, in an electronic voice communication system is provided. The method includes generating a pair of binaural voice signals from the remote talker'"'"'s voice and manipulating the characteristics of the resulting pair of binaural signals. The two ears of the local listener are stimulated binaurally with the pair of binaural voice signals. The stimulating is performed adaptively as the ambient noise in the local listener'"'"'s environment changes, thereby creating a perception of remote talker reacting actively to the local ambient noise, in a psycho-acoustically pleasing manner to the local listener.

8. Non-transitory computer-readable media embodying instructions executable by a computer to perform functions comprising:
-
determining a direction of ambient noise in an environment of a listener; receiving a first audio signal, wherein the first audio signal represents a remote talker'"'"'s voice; generating a first copy of the first audio signal; generating a second copy of the first audio signal; introducing a time delay into the first copy of the audio first signal, wherein a magnitude of the time delay is based on the direction of the ambient noise; causing provision of the first copy to a first ear of the listener subsequent to introducing the time delay; and causing provision of the second copy to a second ear of the listener subsequent to introducing the time delay. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus comprising:
-
a receiver configured to receive first, second, and third audio signals, wherein the third audio signal represents a remote talker'"'"'s voice; a processor configured to determine a direction of ambient noise ambient noise in an environment of a listener based on the first and second audio signals, generate a first copy of the third audio signal, generate a second copy of the third audio signal, and introduce a time delay into the first copy of the third audio signal, wherein a magnitude of the time delay is based on the direction of the ambient noise; a first speaker configured to provide the first copy to a first ear of the listener subsequent to the processor introducing the time delay; and a second speaker configured to provide the second copy to a second ear of the listener subsequent to the processor introducing the time delay. - View Dependent Claims (15, 16, 17, 18, 19, 20)
