AB  - We are addressing the following scenario: A concert is recorded with a stereo microphone technique. Additionally, several instruments/groups of instruments are recorded with spot microphones. The proposed technique adaptively in time estimates the acoustic transfer functions (ATFs) between the spot microphones and the left and right stereo microphones. The spot microphones, filtered with the estimated ATFs, are scaled and subtracted/added from the stereo microphone signals to attenuate or amplify the corresponding instruments. No amplitude panning and reverberators are needed, while the auditory spatial image attributes of the stereo recording are not altered. Other attributes than the level of instruments can be modified by adding/subtracting spot microphones filtered only with the early or late part of the estimated ATFs.
