摘要
以"江南韵"音乐会为对象,在本校音乐厅现场同期录制"高保真"音乐录音作品。通过精确计算和设置拾音器振膜轴线间的夹角、距离,建立ORTF拾音制式。根据音乐厅实际情况,调整录音现场拾音器与舞台的距离、高度和角度,调整输入声卡音频的电平,有效降低舞台硬质反射板的近次反射声比例和背景噪声,获得现场原始的声音素材,制作出"江南韵"音乐会"高保真"录音作品。
＂Jiangnan Music＂ Philharmonic is chosen as an objective to study on the Debugging Live Recording technique. A Chinese Folk Philharmonic is performed in the Concert Hall for celebrating 97th anniversary of our institute. ORTF pickup pattern （Multi -pattern） is set up via the X/Y stereo technique. The axis of two microphones diaphragms is angled at 110 degrees and 17cm distance to each other. This distance and position can finely tune the desired response. According to the architecture of our institute＇ s Concert Hall, the X/Y stereo facing down are placed the front of stage, 1 metre distance and 3metre height with the adjustment of the input level. It is recording around the center of the natural sound sources as more as possible with less proximity effective noise. The high -fidelity audio recordings of ＂Jiangnan Music＂ Philharmonic is made through the mics previous setting.
