20090006488 | USING TIME-STAMPED EVENT ENTRIES TO FACILITATE SYNCHRONIZING DATA STREAMS - An embodiment of a system to synchronize data streams is described. During operation, the system receives a first data stream having a first data type and performs a sequence of operations on at least a portion of the first data stream. Next, the system stores metadata associated with the first data stream one or more times during the sequence of operations. Metadata can include a time stamp, data-stream information associated with the portion of the first data stream, and event information associated with the occurrence of one or more events during the sequence of operations. Moreover, the system provides a notification based on the stored metadata, the notification to facilitate synchronizing the first data stream with a second data stream having a second data type. | 01-01-2009 |
20100063825 | Systems and Methods for Memory Management and Crossfading in an Electronic Device - Systems and methods are disclosed for the management of memory used in a crossfading operation in an electronic device. In one embodiment, a processor is used to alternately decode two audio streams, one which is being faded out and one which is being faded in to implement a crossfade. The two audio streams may be encoded in the same or different formats and may be alternately decoded such that resource usage is reduced. The amount of decoded data of both audio streams and other parameters may determine which audio stream is to be actively decoded. In certain embodiments, the decoded data may be stored in a circular buffer, and a delta is determined between the decoded data and the empty space of the buffer. | 03-11-2010 |
20110039506 | Adaptive Encoding and Compression of Audio Broadcast Data - 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. | 02-17-2011 |
20110039508 | Power Management Techniques for Buffering and Playback of Audio Broadcast Data - Various techniques that relate to prolonging the battery life on a portable electronic device during the buffering and playback of audio broadcast data are provided. In accordance with disclosed embodiments, upon detecting a low power state, the device may implement one or more low power actions, including starting, continuing, or stopping one or more audio broadcast functions, such as buffering or playing back audio broadcast data, to reduce overall power consumption, and thus prolong battery life. In one embodiment, a user may specify one or more low power actions that are to be implemented during a low power state by configuring user settings stored on the device. In another embodiment, the device, upon detecting a low power state, may prompt the user to make a selection from a listing of selectable low power action options and perform the selected low power action. | 02-17-2011 |
20110040981 | Synchronization of Buffered Audio Data With Live Broadcast - 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. | 02-17-2011 |
20110164770 | PROCESSING A MULTI-CHANNEL SIGNAL FOR OUTPUT TO A MONO SPEAKER - Systems, methods, and devices for processing an audio signal with two or more channels into a monaural signal are provided. For example, an electronic device configured to perform such techniques may include audio signal processing circuitry, which may receive a first audio channel signal and a second audio channel signal. Based on these signals, the audio signal processing circuitry may output a monaural signal as a sum or a difference of the first and second audio channel signals, or as a combination thereof, depending at least in part on a phase relationship between the first and second audio channel signals. Additionally or alternatively, the audio signal processing circuitry may adjust a timing relationship between the first and second audio channel signals depending at least in part on the phase relationship, before combining a proportion of the first and second audio channel signals. | 07-07-2011 |
20110166856 | NOISE PROFILE DETERMINATION FOR VOICE-RELATED FEATURE - 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. | 07-07-2011 |

20140129015 | SYNCHRONIZATION OF BUFFERED AUDIO DATA WITH LIVE BROADCAST - 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. | 05-08-2014 |

20100100212 | EFFICIENT TECHNIQUES FOR MODIFYING AUDIO PLAYBACK RATES - 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. | 04-22-2010 |
20100202630 | METHOD AND SYSTEM FOR APPROXIMATING GRAPHIC EQUALIZERS USING DYNAMIC FILTER ORDER REDUCTION - 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. | 08-12-2010 |
