摘要:
This is directed to recommending media items of a user's media library. In particular, this is directed to transferring a portion of the user's media library to an electronic device so that the user may discover the portion of the media library. The library can recommend particular media items to the user using any suitable approach, including for example based on one or more preference profiles. The user can accept or reject recommended media items as they are played back to further adjust the user's preference profile, and to revise the selection of recommended media items stored on the device.

Various techniques for adaptively encoding and compressing audio broadcast data to create a digital representation of the broadcast for storage on an electronic device are provided. In one embodiment, the audio broadcast data may be encoded and stored onto the electronic device using a particular codec and/or compression rate, the selection of which may be based upon one or more characteristics of the audio broadcast data signal, such as a genre parameter or a quality parameter. Particularly, the audio broadcast data may be encoded using either a music codec or a speech codec depending upon the genre parameter. Further, some embodiments may also provide for an adjustable compression bit-rate based at least partially upon the quality parameter of the audio broadcast.

Video data files are provided to a user for playback. Once playback begins, the methods and apparatus of the present invention enable a user to interrupt the video playback function and quickly resume playback prior to reloading the selected video file. The techniques of the present invention can store video data in a cache memory and, upon interruption, capture a frame of video data at approximately the time of the interruption. The captured frame and cache data can be used to provide the user with a unique menu option for resumption of the video playback at the moment of interruption.

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.

Improved approaches to flexibly implementing graphic equalizers on media players are disclosed. These approaches provide dynamic order reduction of a multi-band graphic equalizer so that equalizer effects can be timely performed with only limited computational resources. In one embodiment, a media player receives a media item and associated equalizer settings for a multi-band graphic equalizer. The media player can then automatically (i.e., without user action) approximate the multi-band graphic equalizer with the equalizer settings for the media item using a fewer number of filters. Fewer filters means order reduction, and thus reduction in computational requirements. After the multi-band graphic equalizer is approximated, the media player can present the media item to its user in accordance with the reduced complexity, approximated equalizer.

Systems, methods, and devices for user-specific noise suppression are provided. For example, when a voice-related feature of an electronic device is in use, the electronic device may receive an audio signal that includes a user voice. Since noise, such as ambient sounds, also may be received by the electronic device at this time, the electronic device may suppress such noise in the audio signal. In particular, the electronic device may suppress the noise in the audio signal while substantially preserving the user voice via user-specific noise suppression parameters. These user-specific noise suppression parameters may be based at least in part on a user noise suppression preference or a user voice profile, or a combination thereof.

Systems, methods, and devices for noise profile determination for a voice-related feature of an electronic device are provided. In one example, an electronic device capable of such noise profile determination may include a microphone and data processing circuitry. When a voice-related feature of the electronic device is not in use, the microphone may obtain ambient sounds. The data processing circuitry may determine a noise profile based at least in part on the obtained ambient sounds. The noise profile may enable the data processing circuitry to at least partially filter other ambient sounds obtained when the voice-related feature of the electronic device is in use.

An electronic device for providing tactile feedback is provided. The electronic device may provide tactile feedback using any suitable approach, including for example vibration, heat, electrical, visual, or any other type of feedback. The electronic device may provide tactile feedback in response to detecting any particular status of the electronic device, receiving any particular input, or detecting any suitable communication received by the electronic device. For example, the electronic device may provide tactile feedback in response to receiving a particular user input, or to detecting a user's finger on a particular portion of the electronic device.

Various techniques relating to the alteration of image data are provided herein. An electronic device capable of carrying out such techniques may include data processing circuitry configured to receive image data and detect the occurrence of a device operation event (e.g., an audio event, a motion event, a location event, or an image event, and so forth). The data processing circuitry may alter the image data using a full-quality version or a reduced-quality version of an image alteration effect associated with the device operation event, depending on currently available resources.
