    Abstract: The present aspects relate to audio management for a web browser. For example, an electronic device such as a mobile device may enable a user to navigate to a webpage within a web browser. In some embodiments, the webpage may automatically initiate presentation of audio content. However, the user may wish to quickly silence the audio content that is playing without locating the media player controls of the audio content within the webpage. Accordingly, the present aspects provide audio control for a web browser. Specifically, an audio control affordance may be displayed at a noticeable and recognizable position or area in the web browser, and based on a determination that a webpage includes audio content and/or determination of playback of the audio content. The user may in turn readily adjust a property of the audio content.

  • Patent number: 10374564
    Abstract: Loudness control systems or methods may normalize audio signals to a predetermined loudness level. If the audio signal includes moderate background noise, then the background noise may also be normalized to the target loudness level. Noise signals may be detected using content-versus-noise classification, and a loudness control system or method may be adjusted based on the detection of noise. Noise signals may be detected by signal analysis in the frequency domain or in the time domain. Loudness control systems may also produce undesirable audio effects when content shifts from a high overall loudness level to a lower overall loudness level. Such loudness drops may be detected, and the loudness control system may be adjusted to minimize the undesirable effects during the transition between loudness levels.

  • Patent number: 10109288
    Abstract: An audio encoding device is described herein. The audio encoding device includes a compressor that is based on a nonlinear filter. In particular, the nonlinear filter may be selected from the class of edge-preserving smoothing filters, which avoids common artifacts of conventional compressors. Edge-preserving smoothing filters have been used in image processing algorithms for their de-noising properties while preserving edges in the image. These properties are useful for audio compression because macro-dynamic loudness changes can be tracked precisely while micro-dynamic loudness changes can be ignored for the compression. Due to these advantages, more aggressive compression can be achieved with less distortion.

The media presentation device then reduces a volume level of its audio output. In some instances, volume may be limited during user specified periods.

  • Patent number: 9979366
    Abstract: The invention relates to the measurement and control of the perceived sound loudness and/or the perceived spectral balance of an audio signal. An audio signal is modified in response to calculations performed at least in part in the perceptual (psychoacoustic) loudness domain. The invention is useful, for example, in one or more of: loudness-compensating volume control, automatic gain control, dynamic range control (including, for example, limiters, compressors, expanders, etc.), dynamic equalization, and compensating for background noise interference in an audio playback environment. The invention includes not only methods but also corresponding computer programs and apparatus.

  • Patent number: 9967044
    Abstract: The portable music studio is a modular apparatus that records and mixes music in real time. The portable music studio comprises a dock and a controller. The dock is a switching device that receives a first set of one or more audio signals from a first set of one or more audio sources and routes the each of the received audio signals as a first multichannel audio signal to the controller. The controller is a logic device that independently records each channel of the multichannel signal and directly receives and records a second set of one or more audio sources. The controller mixes this plurality of recorded audio sources. The portable music studio further generates musical audio input directly from the controller. The controller is separable from the dock to allow for recording, mixing and making audio files at a remote location.

  • Patent number: 9967692
    Abstract: Signals in an automobile audio system having at least two near-field speakers located close to an intended position of a listener's head are adjusted such that in a first mode, audio signals are distributed to the near-field speakers according to a first filter that causes the listener to perceive a wide soundstage, and in a second mode, the audio signals are distributed to the near-field speakers according to a second filter that causes the listener to perceive a narrow soundstage. A user input of a variable value is received and, in response, distribution of the audio signals is transitioned from the first mode to the second mode, the extent of the transition being variable based on the value of the user input.

  • Patent number: 9960742
    Abstract: Systems and methods for leveling loudness variation in an audio signal are described. Embodiments use both a perceptual leveling algorithm and a standards-based loudness measure together to minimize audio process artifacts and ensure that the measured loudness of the processed audio is close to a required measure, according to a particular standard measurement of loudness. These systems and methods can be used either offline or in real-time.
