Audio processing method and system based on teaching interaction scene

Abstract

The invention discloses an audio processing method and system based on a teaching interaction scene. The system comprises a first terminal and a second terminal, and the first terminal comprises a courseware playing module, a first processing module, a first physical sound card and a first virtual sound card; the second terminal comprises a second processing module, a second virtual sound card, asecond physical sound card, a sound sending module, a sound receiving module and an audio processing module. The first virtual sound card collects audio data played on the first terminal, and the purpose is achieved that the audio data is transmitted to the second terminal from the first terminal equipment through the first processing module; the second terminal receives the audio data from the first terminal through the second processing module, transmits the audio data to the second virtual sound card and conducts rendering of a real sound card for the second terminal to ensure that local students hear the sound of courseware, and the audio processing module achieves the functions of audio data collection, play and processing; according to the audio processing method and system, audio data transmission among the equipment is achieved through the virtual sound cards, and the requirement of the equipment for the number of physical sound cards is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio processing method and system based on teaching interactive scenes. Background technique [0002] The sound transmission and processing method parameters in the teaching interaction scene in the prior art figure 1 As shown, the Banbantong terminal (for playing teaching courseware), the interactive terminal (for remote interaction), and the microphone will send the captured sound signals to the hardware audio processing matrix through the audio line, and the hardware audio processing matrix will The input sound signal is processed by echo cancellation, sound mixing, etc., and the processed sound signal is sent to the interactive terminal and speakers through the audio line, so as to achieve the purpose of sound interaction between the local classroom and the remote classroom. [0003] In order to carry out sound transmission and processing, a hardware audio proce...

AI Technical Summary

Problems solved by technology

However, when there is no hardware audio processing matrix in the teaching interaction scene, there will be problems such as echo in the interaction, and the inability to hear the sound of the class in the remote classroom. In this case, the sound effect will not meet the expected requirements.
