  • Patent number: 11495240
    Abstract: A device-management system performs processing, such as audio processing, in an instance of a virtual machine corresponding to a functionally limited (local) device. To register the local device, the device-management system receives a registration request that includes device information, encryption data, and an indication of an associated user account. The device-management system then sends this registration data to a service-provider system, which returns a shared encryption key. The device-management system and the local device may use this shared encryption key to securely communicate. The device-management system may de-allocate the instance upon detecting a period of inactivity of the local device and may re-allocate the instance when new activity is detected. The device-management system may further determine when and if audio data to be sent to the local device is encoded using a codec not implemented by the local device.

  • Patent number: 11394356
    Abstract: A system configured to perform audio limiting using block-based processing to reduce acoustic distortion and/or computational cost. While sample-by-sample processing would apply a plurality of gain ramps to a single audio sample, the block-based processing applies a single gain ramp to ensure that the audio sample is below a threshold value. To perform block-based processing, an audio limiter component identifies a maximum amplitude value across all channels for a selected audio frame of an audio signal. Using the maximum amplitude value and the threshold value, the audio limiter component determines a block gain value associated with the selected audio frame and selects between attack processing, hold processing, or release processing. Using the selected processing and the block gain value, the audio limiter component determines instantaneous gain values for the audio samples within the audio frame.

Sound pressure level, SPL, in those sub-bands is then determined, based on the signal energy and based on sound output sensitivity of the against-the-ear audio device. In one instance, at least first and second gain lookup tables are determined based on a hearing profile of a user of the against-the-ear audio device. Sub-band gains that are to be applied to the input audio signal are determined based on the determined SPL. When the input audio signal is for example telephony the sub-band gains are computed using the first gain lookup table, and when the input audio signal is for example media the sub-band gains are computed using the second gain lookup table. Other aspects are also described and claimed.

    Abstract: Components may modify an audio input signal to produce an output audio signal. The audio input signal is firstly rectified and sent to the peak detector as an input control signal. The peak detector produces a peak value which correlates to the level of the input control signal. The control signal is then sent from the peak detector to a dynamic curve module, which has two user selectable inputs: a threshold level and a knee/dynamic angle. The control signal is then sent from the dynamic curve module to the signal dynamics processor. This processor is then configurable to modify the control signal by applying an attack and release phase waveform to elements of the signal which exceed the threshold set by the user. The user will have selected the release time and the release phase shape prior to use of the processor. The release shape is selected by the user.

The system detects an instability condition in a first headphone; generates one or more control signals to adjust one or more ANR parameters of the first headphone using a first controller, wherein the one or more ANR parameters are adjusted to change the first headphone from a first ANR state to a second ANR state to mitigate the instability condition; and synchronizes the one or more ANR parameters of the first headphone with second headphone. In an example, the system returns the first headphone to the first ANR state after detecting that the first headphone was removed from an ear of a user at the first time and detecting that the first headphone was engaged with the ear at the second time.

  • Patent number: 11019440
    Abstract: A method, device, and computer program product for managing transmission of synchronized audio are provided. The method obtains audio test signal (ATS) data based on ATS broadcasts between a group of digital personal assistant (DPA) devices in an environment. The method determines an audible transmission characteristic of interest (COI), with respect to multiple different combinations of the DPA devices from the group of DPA devices, based on the ATS data. The method generates a baseline audio map (BAM) for the group of DPA devices based on the audible transmission COI. The BAM includes compensatory audio settings for locations in the environment. The method configures, for a select location within the environment, one or more current compensatory audio settings for active DPA devices of the group of DPA devices to manage transmission of synchronized audio content at the select location based, at least in part, on the BAM.

  • Patent number: 10951188
    Abstract: A method for adjusting the sound volume of media clips using volume adjuster lines is provided. The volume adjuster lines are individually set for each clip based on the intrinsic, or absolute, volume values of the clip. In some embodiments, the volume adjuster lines are set for each clip based on the peak value or a calculated loudness equivalent of the clip. A user can move the volume adjuster line to set the absolute sound level of a clip. The volume adjuster lines can be hidden in some embodiments. In these embodiments, dragging on any portion of a clip is treated as dragging on the volume adjuster line. Some embodiments provide a deformable volume adjuster line, or curve. In these embodiments, a single audio clip can have several different volume adjuster lines for different sections of the clip where the volume adjuster line for each section is individually adjustable.

  • Patent number: 10884696
    Abstract: Systems and methods are directed to an audio computing device and methods for modifying and/or blending an ambient-sound signal and a non-ambient-sound signal together into a blended signal having one or more desirable characteristics. In some embodiments, the audio computing device may obtain an ambient sound signal by capturing ambient sound with a microphone. The audio computing device may also obtain a non-ambient sound signal that does not represent ambient sounds. The audio computing device may modify one or both of the sound signals to change properties of the sound signals based at least in part on contextual information related to the sound signals, the audio computing device, or the like. The audio computing device may then blend the modified signals together and cause the blended signal to be output as sound via a speaker that provides an improved audio experience for a user of the audio computing device.
