摘要:
A mobile device may include at least one processor configured to generate a first set and second set of processed audio signals for use in a surround sound system. The mobile device may also include at least one output port adapted to provide the first set of processed audio signals for use in the surround sound system to at least two speakers. The mobile device may also include an output port adapted to provide the second set of processed audio signals for use in the surround sound system to headphone speakers.

摘要:
Psychoacoustic Bass Enhancement (PBE) is integrated with one or more other audio processing techniques, such as active noise cancellation (ANC), and/or receive voice enhancement (RVE), leveraging each technique to achieve improved audio output. This approach can be advantageous for improving the performance of headset speakers, which often lack adequate low-frequency response to effectively support ANC.
摘要:
A navigational system generates audio cues that are perceived in a three-dimensional space, allowing users to aurally perceive the locations of mapped objects such as landmarks. The audio cues can be produced alone, or in some applications, produced in conjunction with a visual navigational map display to improve the overall efficacy of the system. The audio navigation system includes a positioning system to determine the location of a user, a memory to store hierarchically-organized information about one or more objects, and a processor to render an audio signal based on the hierarchically-organized information. The audio signal is rendered into an audio space corresponding to the user, so as to allow user perception of the location of at least one of the objects relative to the location of the user. The objects may be landmarks in the vicinity of the user.

An electronic device for generating a masking signal is described. The electronic device includes a plurality of microphones and a speaker. The electronic device also includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a plurality of audio signals from the plurality of microphones. The electronic device also obtains an ambience signal based on the plurality of audio signals. The electronic device further determines an ambience feature based on the ambience signal. Additionally, the electronic device obtains a voice signal based on the plurality of audio signals. The electronic device also determines a voice feature based on the voice signal. The electronic device additionally generates a masking signal based on the voice feature and the ambience feature. The electronic device further outputs the masking signal using the speaker.

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.
摘要:
This disclosure describes audio mixing techniques that intelligently combine two or more audio signals into an output signal. The techniques allow audio to be combined, yet create perceptual differentiation between the different audio signals. The result is that a user is able to hear both audio signals in a combined output, but the different audio signals do not perceptually interfere with one another. The techniques are relatively simple to implement and are well suited for radio telephones.
