摘要： 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.

摘要： As for an audio data outputting apparatus and an audio data inputting apparatus for performing processing on audio data to transfer the audio data at each predetermined frame period, the processing on audio data performed at each frame period is done by hardware other than a CPU so that the CPU will not be interrupted at each frame period. In a case of transfer of audio data from a host to the audio data outputting apparatus, a reproduction control portion controls the data transfer in which a reception buffer and a reproduction buffer are involved, also controlling a receiving portion and a processing portion (DSP). In a case of transfer of audio data from the audio inputting apparatus to the host, a recording control portion controls the data transfer in which a transmission buffer and a recording buffer are involved, also controlling a transmitting portion and a processing portion.

摘要： A digital signal processing device (e.g., DSP), employed by electronic musical instruments and the like, is designed to perform a variety of digital signal processings. The digital signal processing device contains an arithmetic unit which is configured by at least an adder and a multiplier. There are provided first and second microprograms, each of which consists of microinstructions and each of which is designed to perform a specific kind of digital signal processing. The first and second microprograms are alternatively selected in accordance with a preset sequence of processing; and consequently, data supplied to the arithmetic unit are changed in response to the microprogram selected. Thus, the arithmetic unit performs arithmetical operations, using the data selectively supplied thereto, in accordance with the microprogram selected. By changing the sequence of processing, it is possible to easily change a manner of digital computing performed by the digital signal processing device. For example, the first and second microprograms are executed successively in a serial manner or are executed simultaneously in a parallel manner. Preferably, the first microprogram is designed to impart distortion to the data, while the second microprogram is designed to impart reverberation to the data.

摘要： An electronic musical instrument is provided with an input implement for inputting performance information which designates a tone pitch of a musical sound to be produced during the course of performance. A tone generator of a monaural type generates a monaural tone signal having the designated tone pitch. A distributing circuit is connected to the tone generator for distributing the monaural tone signal selectively to a plurality of range channels assigned to different tone pitch ranges. A plurality of acoustic image formers are provided in the respective range channels for processing the distributed monaural tone signal to impart thereto stereophonic spread and location in different manners associated to the different tone pitch ranges. A stereo sound system is connected to the range channels for producing the musical sound having the imparted stereophonic spread and location.

摘要： A detector unit is provided which receives envelope signals related to a predetermined number N of channels to detect a channel showing a greatest or smallest level of the envelope signal among the N channels and outputs data indicative of the detected channel and the level of its envelope signal. When the total number M of the channels is larger than N, a plurality of the detector units are provided, the envelope signals of the number M of the channels are divided into groups numbering not more than N, and the groups are distributed to the respective detector units so that the channel of which level of the envelope signal is the greatest or smallest is detected in each of the detector units. The levels of the envelope signals of the channels detected by the respective detector units are compared with each other, and one detector unit connected with the channel of the greatest or smallest level of the envelope signal is identified. Thus, the channel detected by the identified one detector unit is designated as an extreme-value channel. The designated extreme-value channel is for example a truncating channel to be used for tone generation assignment process.
