摘要： Various techniques for adaptively varying audio feedback data on an electronic device are provided. In one embodiment, an audio user interface implementing certain aspects of the present disclosure may devolve or evolve the verbosity of audio feedback in response to user interface events based at least partially upon the verbosity level of audio feedback provided during previous occurrences of the user interface event. In another embodiment, an audio user interface may be configured to vary the verbosity of audio feedback associated with a navigable list of items based at least partially upon the speed at which a user navigates the list. In a further embodiment, an audio user interface may be configured to vary audio feedback verbosity based upon the contextual importance of a user interface event. Electronic devices implementing the present techniques provide an improved user experience with regard to audio user interfaces.

摘要： Various techniques relating to the buffering of a live audio broadcast on an electronic device and the subsequently playback the buffered data are provided. In one embodiment, the playback speed of the buffered data may be increased relative to the actual speed at which the data was originally broadcasted. If the buffered playback (using the increased playback speed) synchronizes or catches up to the live broadcast, the electronic device may disable buffering and output the live stream instead. This decreases processing demands by lowering processing cycles required for buffering (encoding, etc.) and playback of the buffered data (decoding, etc.), thereby reducing power consumption.

摘要： A technique is provided for displaying pixels of an image at arbitrary subpixel positions. In accordance with aspects of this technique, interpolated intensity values for the pixels of the image are derived based on the arbitrary subpixel location and an intensity distribution or profile. Reference to the intensity distribution provides appropriate multipliers for the source image. Based on these multipliers, the image may be rendered at respective physical pixel locations such that the pixel intensities are summed with each rendering, resulting in a destination image having suitable interpolated pixel intensities for the arbitrary subpixel position.

摘要： Improved techniques for modifying a playback rate of an audio item (e.g., an audio stream) are disclosed. As a result, the audio item can be played back faster or slower than normal. The improved techniques are resource efficient and well suited for audio items containing speech. The resource efficiency of the improved techniques make them well suited for use with portable media devices, such as portable media players.

摘要： Circuits and methods for providing zero-gap playback of consecutive data streams in portable electronic devices, such as media players, are described. In some embodiments, a circuit includes a decoder circuit configured to receive encoded audio data and to output decoded audio data including data streams associated with a data file and a subsequent data file. Moreover, a predictive circuit, which is electrically coupled to the decoder circuit, is configured to selectively generate additional samples based on samples in the data file, where the additional samples correspond to times after the end of a data stream associated with the data file. Additionally, a filter circuit, which is electrically coupled to the decoder circuit and selectively electrically coupled to the predictive circuit, is configured to selectively combine or blend samples at a beginning of the subsequent data file with the additional samples. Note that the circuit may be included in an integrated circuit.

摘要： In operation of an electronics device, audio based on asynchronous events, such as game playing, is intelligently combined with audio output nominally generated in a predictive manner, such as resulting from media playback. For example, an overall audio output signal for the electronic device may be generated such that, for at least one of audio channels corresponding to predictive manner processing, the generated audio output for that channel included into the overall audio output signal is based at least in part on configuration information associated with a processed audio output signal for at least one of the audio channels corresponding to asynchronous events based processing. Thus, for example, the game audio processing may control how audio effects from the game are combined with audio effects from media playback.

摘要： Improved techniques for presenting sound effects at a portable media device are disclosed. The sound effects can be output as audio sounds to an internal speaker, an external speaker, or both. In addition, the audio sounds for the sound effects can be output together with other audio sounds pertaining to media assets (e.g., audio tracks being played). In one embodiment, the sound effects can serve to provide auditory feedback to a user of the portable media device. A user interface can facilitate a user's selection of sound effect usages, types or characteristics.
