Patent ID: 7647127

Claim:
A component data managing method of managing data on components for use in editing signal processing in an audio signal processing system comprising an editing device and a signal processing device, in the system a) the editing device edits, in accordance with a direction accepted on a graphical screen, contents of signal processing to be performed in an audio signal processing device, said contents of signal processing comprising: a plurality of components selected from a set of components, each of which indicates a signal processing function of performing predetermined processing on an inputted signal and outputting the processed signal realized by a signal processor executing a predetermined program in the signal processing device; and wires indicating function of inputting an output from one component to another component, b) the editing device causes the audio signal processing device to perform signal processing in accordance with the edited contents, c) the editing device stores, for each of the set of the components, first component data to be used in the edit of the contents of the signal processing using the graphical screen on the editing device, and second component data including a program for causing the signal processor provided in the audio signal processing device to realize the signal processing function corresponding to the component included in edited contents of the signal processing, and d) the audio signal processing device stores, for each of the set of the components, third component data including a program for causing the signal processor provided in the audio signal processing device to realize the signal processing function corresponding to the component included in edited contents of the signal processing, when the contents of the signal processing edited in the editing device is supplied to the audio signal processing device, said method comprising: storing, by the editing device, the first component data for each of the set of the components with an identifier of the corresponding component; storing, by the audio signal processing device, the third component data for each of the set of the components with an identifier of the corresponding component; when detecting a direction to upgrade the third component data, comparing, by the editing device, the identifier attached to the first component data with the identifier attached to the third component data; and when detecting an identifier attached only to the first component data in said comparing step, transferring by the editing device, the second component data for the component associated with the detected identifier to the audio signal processing device and causing, by the editing device, the audio signal processing device to store the transferred second component data as the third component data.
