Parametric Spatial Audio Coding for Spaced Microphone Array Recordings
Spaced microphone arrays for multichannel recording of music performances, when reproduced in a multichannel system, exhibit reduced inter-channel coherence that translates perceptually to a pleasant ‘enveloping’ quality, at the expense of accurate localization of sound sources. We present a method to process the spaced microphone recordings using the principles of Directional Audio Coding (DirAC), based on the knowledge of the array configuration and the frequency-dependent microphone patterns. The method achieves equal or better quality to the standard high-quality version of DirAC and it improves the common one-to-one channel playback of spaced multichannel recordings by offering improved and stable localization cues.
