Abstract: Systems and methods for “shadowing” a target codec to provide additional features that are not available in the target codec. In one embodiment, an audio amplification system includes a High Definition Audio (HDA) bus, and an HDA controller, a conventional HDA codec and a shadow HDA codec coupled to the HDA bus. The conventional codec receives audio data and commands from the HDA controller via the bus and processes them to generate an output audio signal. The shadow codec snoops the audio data and commands on the HDA bus that are targeted to the conventional codec. The shadow codec processes the snooped audio data and commands to generate a second audio output. The shadow codec does not communicate with the HDA controller and is transparent to the controller. The shadow codec does not request enumeration from the HDA controller and does not receive an address from the HDA controller.

Abstract: Automatic detection of errors among different formatted sound tracks of the same language on a motion picture film stock can be achieved by first acquiring successive audio segments from each of the sound tracks. During a time window of prescribed duration, the audio of each different formatted track undergoes analysis to yield a numeric value. The successive analysis of the audio continues until no further audio exists for analysis. The resultant collection of numeric values undergoes formatting into a numeric file for comparison against a reference file representing audio obtained from a particular source, such as originally recorded material, a sound print, or a duplicated copy of a sound film. If the difference between a formatted numerical file and the reference file exceeds a threshold value, then an error exists in that formatted sound track, and an operator can take appropriate action.

Abstract: This invention has as its object to be able to maintain constant audio data transmission intervals even when video and audio data are transmitted to many users. A group number is assigned to each user, and every time data is generated, it is stored in buffers having different start positions. When a predetermined number of data can be stored, a transmission process to clients is executed. Hence, the load on the transmission processes can be distributed to the number of groups, and the difference of the transmission intervals of audio data can be minimized.

Abstract: The present invention relates to a method of calculating temporal information of frame-based audio stream data, and more particularly, to a method of calculating temporal information of frame-based audio stream data, in which it can calculate time related information depending on the playback of stream data even when bitrate or timetable information is not included in header information when audio or voice stream data consisting of a frame format are played back. Audio and voice stream data applied at this time includes stream data of a type in which several frames form one bit stream block as well as stream data constructed on a frame basis.

Abstract: Audio data are played back by a personal computer a relationship with a playback process recognized easily. Displays showing the contents of play lists are arranged and displayed so that the contents become continuous in sequence in a playback sequence from content that is currently being played back from a display of an operation element that causes an image of a playback process to appear or from a display showing the content which is currently being played back. When the playback of one piece of content of one play list from among a plurality of play lists is terminated and one piece of content of an other play list is played back, at least the content that is currently being played back and content to be subsequently played back are displayed so that the contents can be distinguished.

Abstract: The Procedure executing unit 42 makes a judgment on which among three conditions are satisfied by each of a plurality of audio streams. The BD-ROM reproduction apparatus selects an audio stream to be reproduced in accordance with each combination of conditions that are satisfied by each audio stream. One of the conditions is that a channel attribute of an audio stream is surround and the reproduction apparatus is capable to output surround audio. If the audio stream to be reproduced conforms to an encoding method such as DTS-HD or DD/DD+ whose audio frames are composed of basic data and extended data, the judgment on whether the surround output is available is made by judging whether or not the reproduction apparatus has a capability to process the extended data.

Abstract: A system for determination of the functionality of an audio-related device that is operable in an audio system includes a performance equipment manager. The performance equipment manager may receive from an audio-related device an audio node structure representative of the corresponding audio-related device. The received audio node structure may be reviewed to determine if all the components included in the audio node structure are predefined within the performance equipment manager. For those components that are known, no discovery is necessary and actual values of changeable parameters in the audio-related device may be obtained. For unknown components of the audio node structure, the performance equipment manager may undertake discovery to identify additional portions of the audio node structure, and/or attributes related to the unknown components, in order to obtain actual values of changeable parameters related to the unknown components.

Abstract: A user programmable hearing aid allows a user to select acoustical configuration programs that provide optimum performance for the user. The user may cycle through and evaluate various available programs by operating a single digital rocker switch on the hearing aid housing to switch from one program to the next. When a preferred program is active, the user can press and hold an up control or down control of the digital rocker switch for an extended time to select the currently active program. The user can then use the digital rocker switch to adjust the audio gain for the selected program. The hearing aid may also operate in a Configuration Mode wherein configuration settings may be changed by operating the up and down controls of the digital rocker switch. In the Configuration Mode, a clinician or patient may easily change configuration settings manually, with no need to connect the apparatus to a computer or other programming interface.

Abstract: A vehicle computer system has an audio entertainment system implemented in a logic unit and audio digital signal processor (DSP) independent from the host CPU. The audio entertainment system employs a set of ping/pong buffers and direct memory access (DMA) circuits to transfer data between different audio devices. Audio data is exchanged using a mapping overlay technique, in which the DMA circuits for two audio devices read and write to the same memory buffer. The computer system provides an audio manager API (application program interface) to enable applications running on the computer to control the various audio sources without knowing the hardware and implementation details of the underlying sound system. Different audio devices and their drivers control different functionality of the audio system, such as equalization, volume controls and surround sound decoding. The audio manager API transfers calls made by the applications to the appropriate device driver(s).

The method of estimating an impulse response for a reverberant system includes sampling a signal from a reverberant system, having an impulse response, into a sequence of blocks, for each block of the sequence, determining a magnitude in dependence upon a magnitude of a previous block, forming an estimate of the impulse response using determined magnitudes as parameters for a finite impulse response filter.

Abstract: A particular program detection device detecting a particular program segment even in a program signal contaminated with noise by adaptively modifying a detection sensitivity for a scene change point. A noise level detecting section detects a noise level of a program signal outputted from a signal input section. Based on the detected noise level, a detection sensitivity determining section determines a detection sensitivity which is used when a silent portion of the program signal is determined by a silent portion detecting section. In accordance with the determined detection sensitivity, the silent portion detecting section detects a portion having a low audio level of the program signal as a silent portion. A particular program determining section calculates a time difference between each silent portion and a silent portion following this, and based on the calculated time difference, determines whether or not the silent portion is a particular program.
