    Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.

    Abstract: An audio normalization gain value is applied to an audio signal to produce a normalized signal. The normalized signal is processed to compute dynamic range control (DRC) gain values in accordance with a selected one of several pre-defined DRC characteristics. The audio signal is encoded, and the DRC gain values are provided as metadata associated with the encoded audio signal. Several other embodiments are also described and claimed.

    Abstract: An audio encoding device and an audio decoding device are described herein. The audio encoding device may examine a set of audio channels/channel groups representing a piece of sound program content and produce a set of ducking values to associate with one of the channels/channel groups. During playback of the piece of sound program content, the ducking values may be applied to all other channels/channel groups. Application of these ducking values may cause (1) the reduction in dynamic range of ducked channels/channel groups and/or (2) movement of channels/channel groups in the sound field. This ducking may improve intelligibility of audio in the non-ducked channel/channel group. For instance, a narration channel/channel group may be more clearly heard by listeners through the use of selective ducking of other channels/channel groups during playback.

    Abstract translation: 这里描述了音频编码装置和音频解码装置。 音频编码设备可以检查表示一段声音节目内容的一组音频频道/频道组，并产生一组与频道/频道组中的一个相关联的候选值。 在播放声音节目内容期间，可以将所有其他频道/频道组应用于所述下列值。 这些躲避值的应用可能会导致（1）下行通道/通道组的动态范围的减少和/或（2）声场中通道/通道组的移动。 这种躲避可能会提高非庇护频道/频道组中音频的清晰度。 例如，听众可以通过在播放期间通过使用其他频道/频道组的选择性躲避来更清楚地听到旁白频道/频道组。

    Abstract: Techniques are provided for determining, at an audio processing device, whether to produce high quality or low quality audio output based on one or more factors. The one or more factors may include the type of output device (e.g., headphones, built-in speakers, or USB audio devices) that is connected to the audio processing device and whether certain operations (e.g., mixing and/or scaling) are to be performed on the decoded audio content. Thus, the highest quality audio output is produced based on current conditions of the audio system, which includes the output device. If the current conditions of the audio system indicate that producing high quality audio output does not yield sufficient perceived benefits, then the audio processing device may produce lower quality audio output.
