一、拾音本文就古典音乐中的交响乐、室内乐和合唱来叙述整个西洋乐的拾音方法。为了拾取声音,使用各种指向性的传声器,在可调指向性传声器还未开发时,仍需要使用适合于不同拾音目的的各种传声器,而且传声器并不具备非常完好的指向性,不象照相机,在镜头摄影角度以外的光线是不可能进入的。即使用指向性传声器,只是该方向的灵敏度比其他方向高得多,但是仍可以从侧面、背面、上下方向拾取声音。因此,不可能从音乐演秦中只拾取特定乐器的声音。这个问题使得传声器的布置和调音操作在音频拾音中,变得很麻烦。
First, the pickup This article on the classical music symphony, chamber music and chorus to describe the Western music collection method. In order to pick up the sound, various directional microphones are used. When the adjustable directional microphones have not been developed yet, various microphones suitable for different sound pickup purposes are still required and the microphones do not have very good directivity. Cameras, it is impossible to enter the light outside the lens photography angle. Even with a directional microphone, except that the sensitivity of the direction is much higher than the other directions, it is still possible to pick up the sound from the side, back, and up and down. Therefore, it is impossible to pick up only the sound of a specific instrument from the musical performance Qin. This problem makes the microphone arrangement and tuning operation in the audio pickup, become very troublesome.
