Abstract: A normalization for streaming digital audio signals applies a gain factor according to the maximum sample magnitude in a window of samples and compare the gain factor to prior gain factors to adjust the gain factor for the samples in the window of samples. Adaptation of the gain factor with rapid decreases but slow increases avoids saturation but allows quiet passages.

Abstract: A media player coupled to a network contains a processor, non-volatile memory, volatile memory, a driver, and input and output ports. The media player receives a media file over the network that contains an encoded media stream and a universal decoder. The player's processor converts or translates (or otherwise generates) the universal decoder into a player-specific decoder which may differ from the universal decoder. A library of routines stored in the non-volatile memory is used to create the player-specific decoder. The media stream downloaded to the media player may comprise audio, video, or any other desired type of media. In this manner, each media player can generate a decoder that differs, not only from the universal decoder, but may also differ from other media players thereby alleviating the burden on the media source from having to download the encoded media with a decoder specific to the target media player.

Abstract: A computer implemented method of multi-threaded data processing operation partitions each data processing module into at least five sub-modules including (1) receiving messages, (2) processing received messages, (3) getting resources for module function, (4) performing a core data processing operation of the module and (5) outputting resources generated. These modules are launched and retired as needed in a multi-threaded environment. A framework includes APIs for the module and each sub-module. The message and data handling sub-modules are optionally shared among modules.

Abstract: A file is to be transferred over the internet employs TCP/IP procedures to insure accurate transmission of the file. When, in a processing system, a URL request for a file is generated, a determination is made whether the requested file is stored in a device associated with processing system issuing the URL request. When the requested file is stored in a storage unit connected to the data processing system requesting the file, then the TCP/IP procedures are not used. When the file must be transferred over the internet, i.e., the device storing the requested file is not associated with the processing system requesting the file, then the TCP/IP procedures are employed. In this manner, the TCP/IP procedures have a reduced impact on the availability of the central processing unit.

Abstract: In order to power the components providing wireless audio transmission from an audio signal source unit, the audio signal source uses the audio signal itself, after rectification and demodulation, to provide power to the components providing the wireless signal. Similarly, for an audio receiving unit, the power provided by the microphone pickup voltage can be used to detect and demodulate the wireless signal. These audio components can therefore be provided with wireless capability without requiring an external power source.
