    摘要： A first digital signal processor (DSP) associated with a first user outputs audio to the first user via first headphones, and captures speech from the first user via a first microphone. Similarly, a second DSP associated with a second user outputs audio to the second user via second headphones, and captures speech from the second user via a second microphone. The first DSP is coupled to the second DSP in order to allow the first and second users to share music and communicate with one another. The first user may speak into the first microphone, and the first and second DSPs may then interoperate to output that speech to the second user without substantially disrupting audio output to the second user. Each of the first and second users may also select between first and second audio sources that may be coupled to the first and second DSPs, respectively.

    摘要： A multiband ducker is configured to duck a specific range of frequencies within a music signal in proportion to a corresponding range of frequencies within a speech signal, and then combine the ducked music signal with the speech signal for output to a user. In doing so, the multiband ducker separates the music signal into different frequency ranges, which may include low, middle, and high-range frequencies. The multiband ducker then reduces the amplitude of the specific range of frequencies found in the speech signal, typically the mid-range frequencies. When the ducked music signal and the speech signal are combined, the resultant signal includes important frequencies of the original music signal, including low-range and high-range, thereby allowing perception of the music signal to continue in relatively uninterrupted fashion. Additionally, the combined signal also includes the speech signal, allowing for the perception of intelligible speech concordant with the perception of music.

    摘要： An audio processing system for a listening device includes an input device, a voice activity detector and a ratio-based attenuator. The input device is configured to receive a first audio signal emanating from an environment and including a signal of interest. The voice activity detector is configured to generate a control signal in response to the first audio signal. The ratio-based attenuator is configured to receive the control signal and determine whether the signal level of the first audio signal exceeds the signal level of an audio signal received from an audio playback device by at least a target difference. If so, then the audio level of the playback audio signal is maintained. Otherwise, the audio level of the playback audio signal is adjusted, where, at the adjusted value, the first signal level exceeds the playback signal level by at least the target difference.

    摘要： One or more embodiments set forth include a personal aural device that includes an expandable eartip. The expandable eartip has a contracted state and an expanded state. The expandable eartip includes an insertion sensor configured to receive an indication that the eartip has been placed in an ear of a user. The expandable eartip further includes a controller configured to, in response, actuate a first device to inflate a first chamber to conform to a first portion of the ear. At least one advantage of the described techniques is that eartips in a set of earphones automatically inflate to provide an optimal fit for any listener's ears.

    摘要： In one embodiment, a recording optimizer included in a recorder optimizes the fidelity of output signals. In operation, the recorder receives and records two sets of input signals—one set of input signals received via microphones included in the recorder and another set of input signals received as line-inputs from a front of house console mixer. The recording optimizer analyzes the recorded signals to identify discrepancies, such as unamplified instruments that are underrepresented in the line-inputs. The recording optimizer then performs compensation operations that adjust one or more recorded signals to mitigate the discrepancies. Subsequently, the recording optimizer combines the compensated recorded signals, generating output signals that leverage the strengths of both sets of input signals to accurately represent the experienced sound. By contrast, conventional recorder/mixer combinations may produce output signals with degraded fidelity attributable to unresolved discrepancies between the source signals.

    摘要： An audio processing system includes a group of microphones associated with a dynamic network of microphones and a receiver. The receiver is configured to identify a first signal received by a microphone in the plurality of microphones that is designated as a primary microphone, and identify a subset of microphones included in the plurality of microphones, where each microphone in the subset is associated with a respective signal corresponding to the first signal. The receiver is further configured to calculate a weighting factor for each microphone included in the subset based on the first signal and the respective signal and opportunistically establish a connection with a microphone associated with the dynamic network of microphones that is not included in the plurality of microphones; and, based on a signal received from this microphone, adjust a weighting factor for at least one of the microphones in the subset.
