摘要： A method and device for providing visualizations on a media player is described. The method may comprise monitoring playback of an audio stream on the media player selecting visualization data stored on the media player. The visualization data may be previously rendered and including at least one element derived from an audio stream. Thereafter, the selected visualization data is displayed and the audio stream is rendered on the media player. For example, the selected visualization data may be automatically without human intervention rendered in synchrony with the audio stream. The media player may be a portable media player and the visualization data may comprise dynamic element(s) and static element(s). The method may update the dynamic element(s) based on an update algorithm.

摘要： A system and method for preserving the natural sound of a signal that is processed by an analysis step of converting the signal into a sequence of overlapping windowed DFT representations and a synthesis step of converting these DFT representations back to a time domain signal. For example, the system and method are applicable to analysis-synthesis systems based on a sequence of overlapping windowed, DFT representations in which either: (1) the analysis transforms overlap in time by a different amount than the synthesis transforms, or (2) the modification involves a re-mapping of transform values from one frequency location to another. The phases of the complex-valued DFT representations may be modified so that synthesis of the time domain signal results in a natural sound despite the effects of e.g., either (1) or (2).

摘要： A system for pitch-shifting an audio signal wherein resampling is done in the frequency domain. The system includes a method for pitch-shifting a signal by converting the signal to a frequency domain representation and then identifying a specific region in the frequency domain representation. The region being located at a first frequency location. Next, the region is shifted to a second frequency location to form a adjusted frequency domain representation. Finally, the adjusted frequency domain representation is transformed to a time domain signal representing the input signal with shifted pitch. This eliminates the expensive time domain resampling stage and allows the computational costs to become independent of the pitch modification factor.
