In the traditional RTC (voice communication) scenario, the entire processing chain of the audio engine, such as 3A algorithm, codec, packet loss compensation and other technologies, only processes voice. In real-time interactive entertainment scenarios (such as host Lianmai, interactive podcasts, game voice, etc.), music, sound effects, etc. will be involved. When an audio engine with the goal of optimizing voice quality is faced with such scenarios, the sound quality after algorithm processing will be different. Great discount. For example, the frequency of double-talk problems in voice scenes is low. However, when the music is always playing, as long as the other end talks, double-talk will be formed. If the echo cancellation is not handled properly, it will cause great damage to the voice or music; For example, the noise reduction algorithm will inevitably damage the music when it encounters music. Therefore, in the real-time interactive entertainment scene, it is necessary to optimize the entire audio algorithm processing link of the audio engine to improve the sound quality in the real-time interactive entertainment scene as much as possible.
