PURPOSE: A record/reproduction synchronizing method of a multichannel voice processing board is provided to make all multichannel digital signal processors request to firmware when completing a voice data processing, every time when completing the voice data processing, not to miss voice data even when variable voice data is processed, so as to prevent the voice data from being lost. CONSTITUTION: A digital signal processor informs firmware of a voice processing-completed channel(410). The digital signal processor checks a voice processing request for multichannels from the firmware, and displays the voice processing request(420). The digital signal processor decides whether all of voice processing of the multichannels are displayed(430). If not, the digital signal processor adds the multichannels one by one to display all of the voice processing, and checks the voice processing request to display the request(440). If all of the voice processing are displayed, a multichannel voice processing is requested to the firmware(450). The digital signal processor decides whether a voice processing-completed channel exists(460). If so, the digital signal processor re-requests a voice processing(470). |
