With the rapid popularization of mobile phone karaoke OK or mobile phone karaoke APP (such as national karaoke and singing bar) and short video platform APP (such as trembler and handedness), singing, recording and shooting short videos by using a mobile phone at any time and any place become a recreational activity which is very popular with consumers.
At present, various mobile phone sound cards or live broadcast sound cards are matched with common mobile phone K song auxiliary equipment for singing songs of mobile phones, and the main functions of the equipment are to process voices and accompanying music in real time, so that the recording listening feeling and the use experience are improved.
When shooting singing short videos, some mobile phone APPs can provide real-time accompaniment music (such as the national karaoke and singing bars), some mobile phone APPs do not provide real-time musical accompaniment (such as trembling and fast hands), or a user wants to use accompaniment music other than APPs. When a first mobile phone (live mobile phone) recording a short singing video does not provide accompaniment music or a user wants to use accompaniment music other than APP, the consumer needs to use a second mobile phone (which can also be a computer or traditional music playing equipment) to play the accompaniment music, at the moment, the accompaniment music and the singing voice are simultaneously input into a sound card, the sound card performs sound effect processing on the accompaniment music and the singing voice, then the sound is output to the first mobile phone (live mobile phone), the recording of the sound is completed, and the video recorded simultaneously with the mobile phone is synthesized into a complete audio and video clip.
