The system may also comprise a network interface configured to enable the system to exchange media signals with other devices on a common network, and a reference clock configured to provide a common clock signal to the at least one virtual media card, the at least one media interface, and the common network. An advertisement and discovery module configured to identify when the at least one application is started and/or stopped and when the at least one media card is attached and/or detached from the system may also be provided. The advertisement and discovery module is configured to: (i) make I/O channels of the at least one media card available to the system and the common network, and (ii) make I/O channels of the at least one application available to the system and the common network.

摘要： An integrated circuit for digital signal routing. The integrated circuit has analog and digital inputs and outputs, including digital interfaces for connection to other integrated circuits. Inputs, including the digital interfaces, act as data sources. Outputs, including the digital interfaces, act as data destinations. The integrated circuit also includes signal processing blocks, which can act as data sources and data destinations. Signal routing is achieved by means of a multiply-accumulate block, which takes data from one or more data source and, after any required scaling, generates output data for a data destination. Data from a data source is buffered for an entire period of a data sample clock so that the multiply-accumulate block can retrieve the data at any point in the period, and output data of the multiply-accumulate block is buffered for an entire period of the data sample clock so that the data destination can retrieve the data at any point in the period. Multiple signal paths can be defined by configuration data supplied to the device, either by a user, or by software. The multiply-accumulate block operates on a time division multiplexed basis, so that multiple signal paths can be processed within one period of the sample clock. Each signal path has a respective sample clock rate, and paths with different sample clock rates can be routed through the multiply-accumulate block on a time division multiplexed basis independently of each other. Thus, speech signals at 8 kHz or 16 kHz can be processed concurrently with audio data at 44.ikHz or 48 kHz.

摘要： Systems and methods are presented for cross-fading (or other multiple clip processing) of information streams on a user or client device, such as a telephone, tablet, computer or MP3 player, or any consumer device with audio playback. Multiple clip processing can be accomplished at a client end according to directions sent from a service provider that specify a combination of (i) the clips involved; (ii) the device on which the cross-fade or other processing is to occur and its parameters; and (iii) the service provider system. For example, a consumer device with only one decoder, can utilize that decoder (typically hardware) to decompress one or more elements that are involved in a cross-fade at faster than real time, thus pre-fetching the next element(s) to be played in the cross-fade at the end of the currently being played element. The next elements(s) can, for example, be stored in an input buffer, then decoded and stored in a decoded sample buffer, all prior to the required presentation time of the multiple element effect. At the requisite time, a client device component can access the respective samples of the decoded audio clips as it performs the cross-fade, mix or other effect. Such exemplary embodiments use a single decoder and thus do not require synchronized simultaneous decodes.

摘要： Some embodiments of the invention are directed to enabling a user to easily identify the frequency range(s) at which sound masking occurs, and addressing the masking, if desired. In this respect, the extent to which a first stem is masked by one or more second stems in a frequency range may depend not only on the absolute value of the energy of the second stem(s) in the frequency range, but also on the relative energy of the first stem with respect to the second stem(s) in the frequency range. Accordingly, some embodiments are directed to modeling sound masking as a function of the energy of the stem being masked and of the relative energy of the masked stem with respect to the masking stem(s) in the frequency range, such as by modeling sound masking as loudness loss, a value indicative of the reduction in loudness of a stem of interest caused by the presence of one or more other stems in a frequency range.

摘要： A first adjuster (fader) adjusts volume of an input sound signal and sends the volume-adjusted sound signal to a first output destination. A second adjuster adjusts the volume of the sound signal before being subjected to the volume adjustment by the first adjuster (pre-fader sound signal) or the sound signal after having been subjected to the volume adjustment (post-fader sound signal). The second adjuster sends the volume-adjusted sound signal to a second output destination (such as a monitor output) different from the first output destination (such as a main output). A selector selects one of the pre-fader and post-fader sound signals. The sound signal selected by the selector is input to the second adjuster for volume adjustment. When the selection by the selector is changed, a controller changes the volume adjustment by the second adjuster on the basis of a volume difference between the pre-fader and post-fader sound signals.
