In this study we made three separate recordings using both close, near, and room microphones. These recordings were then the subject for a listening test constructed to study a variety of perceived effects due to manipulating time in overdub recordings. While the use of time alignment to decrease comb filtering has been widely studied, there has been little work on investigating other perceived effects. Time alignment has become more and more common, but as this paper concludes, it should not be used without concern. The findings will shed light on a range of important factors affected by manipulating time between microphones in overdub recordings, while also concluding on which of, and when, the investigated techniques are normally preferred or not.
