Ambience Sound Recording Utilizing Dual MS(Mid-Side) Microphone Systems Based Upon Frequency Dependent Spatial Cross Correlation (FSCC)
In musical sound recording for CD production or broadcasting, a forest of microphones is commonly observed. They are for good sound localization and favorable ambience, however it is desirable to make the forest sparse for less laborious setting up and mixing. Previously, we examined ambience representation of stereophonic microphone arrangements utilizing Frequency Dependent Spatial Cross Correlation (FSCC). FSCC is defined as a cross correlation of outputs by two microphones that of MS microphone system is most favorable. Based upon the result, we devised combination of two MS microphone systems, one is for acquisition of stage sounds and the other is for ambience representation. In addition to minor stage microphones we achieved satisfactory musical recording.
