Abstract:
1. An audio signal processing system comprising: a computer that executes application software to realize a function of a recording and editing device that records and edits the audio signals; and an audio signal processing device that processes the audio signals, said computer and said audio signal processing device being connected via a communication path through which a control signal and plural audio signals can be transmitted, wherein said computer comprises a transmission and reception device that receives the audio signals sent by said audio signal processing device to supply to said recording and editing device and transmits the audio signals supplied from said recording and editing device to said audio signal processing device via the communication path, wherein said audio signal processing device comprises: an input device that inputs an audio signal from outside the device; one or more input channels that controls a characteristic of the audio signal inputted from the input device; a transmission and reception device that transmits the audio signals from the input channels to said computer via the communication path and receives plural audio signals, including an audio signal of a second bus, from said computer via the communication path; a first mixing bus that mixes the audio signals supplied from each of the input channels and the audio signal of said second bus supplied from said transmission and reception device; and a first selecting device that selects, for each of said input channels, one of an audio signal received from said computer via the communication path and an audio signal inputted by said input device, according to user's setting, and supplies the selected audio signal to the input channel, wherein said recording and editing device comprises: a plurality of tracks that record and/or reproduce audio signals inputted to the tracks from said transmission and reception device; a plurality of track channels, each of which corresponds one of the tracks and selectively inputs an audio signal inputted from the track or an audio signal reproduced in the track to control a characteristic of the audio signal; a second selecting device that, for each of the track channels, selectively executes one of supplying the audio signal from the track channel to said transmission and reception device to transmit the audio signal to said audio signal processing device and supplying the audio signal from the track channel to said second mixing bus, according to user's setting; and said second mixing bus that mixes the audio signals supplied from the second selecting device and supplies the mixed audio signal to said transmission and reception device to transmit the mixed audio signal to said audio signal processing device, and wherein said audio signal processing device and said computer cooperatively operates such that: when a first instruction is inputted to said audio signal processing system by the user, said audio signal processing device controls said first selecting device to select, for all of said input channels, said audio signals inputted by said input device and said computer controls said second selecting device to supply the audio signals from all of the track channels to said second bus; and when a second instruction is inputted to said audio signal processing system by the user, said audio signal processing device controls said first selecting device to select, for all of said input channels, said audio signals received from said computer via the communication path and said computer controls said second selecting device to supply audio signals from all of the track channels to said transmission and reception device to transmit the audio signals to said audio signal processing device.
