    摘要： A signal processing apparatus has a first memory in which plural pieces of FIR coefficient data used for implementing an FIR filter algorithm are stored, a second memory which stores plural pieces of input data to be subjected to the FIR filter algorithm, and a processor implements the FIR filter algorithm using the plural pieces of FIR coefficient data stored in the first memory and the plural pieces of input data stored in the second memory as many times as the number corresponding to a designated filter order, in which filter algorithm each piece of coefficient data and each piece of input data are multiplied together and resultant products are summed up. The signal processing apparatus is provided, which can implement plural sorts of FIR filter algorithms of filter order which can be changed flexibly.

    摘要： An apparatus for combining input signals produced by a plurality of electric musical devices includes a plurality of audio buses and a plurality of segments. Each segment includes input circuitry configured to receive at least one input signal from at least one electric musical device and to deliver the at least one input signal to one of the plurality of audio buses; a plurality of variable adjustment devices each associated with a corresponding one of the audio buses and each configured to change at least one property of an input signal received by another of the plurality of segments and carried on the corresponding one of the audio buses independent from input signals carried on other of the plurality of audio buses; and a mixer configured to combine the input signals carried on each of the plurality of audio buses into an output signal.

    摘要： An audio depth dynamic range enhancement system and method for enhancing the dynamic range of depth in audio sound systems as perceived by a human listener. Embodiments of the system and method process an input audio signal by applying a gain function to at least one of a plurality of sub-signals of the audio signal having different values of a spatial depth parameter. The sub-signals are combined to produce a reconstructed audio signal carrying modified audio information. The reconstructed audio signal is output from the system and method for reproduction by the audio sound system. The gain function alters the gain of the at least one of the plurality of sub-signals such that the reconstructed audio signal, when reproduced by the audio sound system, results in modified depth dynamic range of the audio sound system with respect to the spatial depth parameter.
