摘要： A method and system for performing sample rate conversion is provided. The method may include configuring a system to convert a sample rate of a first audio channel of a plurality of audio channels to produce a first audio stream of samples. The system may be dynamically reconfigured to convert a sample rate of a second of the plurality of audio channels to produce a second audio stream of samples, wherein the first and second audio streams are output from the system at the same time. The method may further include arbitrating between request for additional data from the first and second audio stream of samples, where processing of the first channel is suspended when the request corresponds to a second channel that is of higher priority.

摘要： Embodiments of the invention describe a method of generating an enhanced audio stream. The enhanced audio stream is generated from live audio received and accompanies a live video broadcast. This live audio is buffered and combined with a visual description of the live video broadcast. Together these form an enhanced audio stream. The visual description is entered by a visual describer while they are viewing a an instantaneously updated visual buffer size display. The visual buffer size display is calibrated to a pre-set maximum buffer size, and shows the pre-set maximum buffer size and the current buffer size in a visual manner. Further, live audio from the buffer that is inserted into the enhanced audio stream is compressed in time.

摘要： A system for selection by a user and delivery to the user over an internetwork transmission channel of selected audio data files at a delivery rate of at least twice the delivery rate for normal, audibly perceptible playback of an audio data file. The user registers the user's selection of audio material with a central library of audio and/or text data files, and a digitized and optionally compressed omnibus file containing the user's selections is prepared and transmitted to the user at a high data transfer rate. The user receives downloads the selected data files to a personal computer or to a portable storage and playback unit (SPU) that may store and play back digitized text or audio data, using a docking station. The user carries this SPU until the user has an opportunity to audio process and play back the text or audio data files in audibly perceptible form.
