拾音时应当充分利用声源的辐射特性来设置传声器,并考虑到反射声的作用,通过利用压限器合理压缩节目的动态范围和利用频率均衡器、激励器提高信号的谐波分量两种方法来提高节目响度。 Sound pickup should make full use of the radiation characteristics of the sound source to set the microphone, and taking into account the role of reflected sound by compressing the program reasonable use of the dynamic range of the program and the use of frequency equalizer, the exciter to improve the signal harmonic components of two Method to improve program loudness.
