Simulation system for processing of multiple paths of real-time audio signals

Abstract

The invention provides a simulation system for processing of multiple paths of real-time audio signals. Through adoption of the simulation system, resource allocation can be performed during running; an actual hardware environment can be accessed and controlled; and real-time audio signal processing can be finished. According to the technical scheme, the system is implemented by the following steps: during working of an audio exchange subsystem, transmitting digital audio data to a control computer through a digital audio module, exchanging data between the control computer and an audio switch in a TCP (Transmission Control Protocol) / IP (Internet Protocol) network communication packet way, building an audio simulation network system, configuring audio channel resources, and creating a conference group sound mixing model; binding voice information from different equipment with audio resources through audio simulation control software, and processing data from the digital audio module, an I / O (Input / Output) control module and the audio switch; and judging a communication line according to a call priority, introducing the digital audio data into the audio switch, mixing sounds of multiple paths of audios by the audio switch, and outputting mixed sound of analog audio and digital audio.

Description
