Sound Acquisition And Sound Adjustment Of Multi-channel Miking Techniques In Piano Concert Recordings

In the recording process of piano concert,many factors affect the collection of piano sound and the improvement of sound quality.The sound diffusion and the acoustic structure of the room affect the spatial sense of piano sound;the selection and placement of microphone affect the frequency response of picking up piano sound;the effector and digital information arrangement in post production affect the sound quality of the whole piano sound.This paper will focus on X/Y,A/B,M/S and other stereo sound picking technology and multi-channel stereo sound picking technology to collect the piano concert sound frequency response,dynamic range,horizontal and vertical spatial sense for specific data analysis,and combined with the use of post-effect device and digital audio arrangement,study how to achieve the platform piano recording sound quality improvement in the practice of piano concert recording,improve the frequency response,dynamic range,horizontal and vertical spatial sense of each frequency band audio.
