    摘要： A filter coefficient group computation device is configured from a means for performing inverse Fourier transform on a frequency characteristic inputted through an input means; a means for performing short-term Fourier transform on a numerical string obtained by the inverse Fourier transform; a means for performing windowing on a frequency domain signal, obtained by the short-term Fourier transform, using a function of which a window length shortens as frequency increases; a means for performing short-term inverse Fourier transform on the frequency domain signal after the windowing; a means for performing overlap addition on a numerical string obtained by the short-term inverse Fourier transform; and a means for determining a numerical string after the overlap addition as a filter coefficient group which forms a filter having the frequency characteristic inputted through the input means.

    摘要： The invention relates to a device for treating or acting on workpiece surfaces by means of an actuator, such as a cutting or engraving laser or a nozzle for applying oils, paints, adhesives, dyes, or etchants for example. In particular, the invention relates to a device which is suitable for acting on workpieces with relatively large surfaces relative to the dimensions of the actuator, such as on strip materials for example. An ultrasonic levitation force field is generated by means of a sonotrode (4), which is coupled to the actuator into a working unit (3), such that the movably suspended working unit (3) is supported on the workpiece surface in a hovering manner. The ultrasonic levitation force field allows a highly precise positioning of the working unit (3) relative to the workpiece surface so as to allow a precise treatment or machining of the workpiece surface.

    摘要： An audio signal processing system is configured to separate an audio signal into a dry signal component and one or more reverberant signal components. The dry signal component and the reverberant signal components can be separately modified and then recombined to form a processed audio signal. Alternatively, the dry signal component may be combined with an artificial reverberation component to form the processed audio signal. Modification of the reverberation signal component and generation of the artificial reverberation component may be performed in order to modify the acoustic characteristics of an acoustic space in which the audio signal is driving loudspeakers. The audio signal may be a pre-recorded audio signal or a live audio signal generated inside or outside the acoustic space.

    摘要： The beginning detection, accommodation and frequency bias properties of the human hearing mechanism have been modeled to create systems that can detect directional transients ("sound events") in a sound field and localize them. These systems break down a sound field into sound events and non-sound events and separately localize the sound events and non-sound events. Sound events are generally identified according to the frequency bias and beginning detection properties. Once detected, the sound events are generally localized according to differential steering angles (steering angles to which the steady-state signals have been accommodated) or ordinary steering angles, both of which reflect the direction of a sound event indicated during the rise-time of the sound event. When no sound events are detected, non-sound events are localized according to a steering angle that does not reflect rapid motion.
