中文摘要:
      声音信号的重要计量值为 VU 值和峰值,它们分别直观反映声音强度及失真情况。为了透彻分析和阐述电影音乐节目制作系统的特性,该文通过实验的方法,测量了大量乐器在典型演奏法下的 VU值和峰值。进而通过实验数据的结果,做出 P/VU概率分布曲线。各音乐信号的 P/VU分布情况决定了系统的电平储备,掌握此结论非常有助于进行电影音乐节目制作过程中的电平控制。
英文摘要:
      The important values of sound signal are VU and peak, which shows the intensity and the distortion of sound separately. In order to analyze and show the character of film music making system deeply, from experiments, mass of the VU and peak values of instrument in common performance ways are measured. And the chart of P/VU probability distribution is made by the experiment data. The distribution of P/VU values of music signals decides the head room of the system, which is good for level controlling on film music program making.
