Abstract: User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. Digital audio signals processed by a first signal processing circuit are stored into a memory and transmitted to a second signal processing circuit via a cascade-connection. The second signal processing circuit adds the audio signal, processed for each of the steps, to audio signals input via the cascade-connection and writes added signal into the memory.

Abstract: A signal processing device is designed to automatically calculate a transfer characteristic representing sound-box resonance of a guitar due to acoustic excitation of vibration which may occur due to white noise. White noise emitted toward the guitar causes vibration propagating via strings so as to produce an audio signal via a pickup. A transfer characteristic is calculated based on an audio signal and a white-noise signal. A filter performs convolution, using the transfer characteristic, on audio data representing user's playing sound of the guitar, thus reproducing sound-box resonance indicating distinctive peaks which may appear in a low-frequency range of guitar's sound. It is possible to store a plurality of transfer characteristics in memory, whereby any user may be allowed to select a desired transfer characteristic among transfer functions stored in memory or to utilize a transfer characteristic actually calculated by the signal processing device.

Abstract: An acoustic structure (e.g. an acoustic tuning panel) includes a plurality of boards and a plurality of resonance tubes with a plurality of openings. The openings are formed at different positions on the side faces of the resonance tubes. One resonance tube may be interposed in and supported by a pair of boards, or one board may be interposed in and supported by a pair of resonance tubes. The resonance tubes are mutually movable in the axial direction so as to independently adjust the opening area of the opening of the resonance tube. With this behavior, it is possible to adjust a ratio of the opening area of the resonance tube to the sectional area of the internal cavity of the resonance tube, thus adjusting the bandwidth of a band causing a sound-absorbing effect and a sound-scattering effect in an acoustic space (e.g. a sound chamber).
