Abstract
An in-line early enhancement generation system comprises one or more microphones (m1 to mn) positioned close to one or more sound sources so as to detect predominantly direct sound, an early reflection generation stage (using transfer function matrix X(f)) which generates a number of delayed reproductions of the microphone signals and which has unitary power gain whereby the stability of the system is independent of the delay times and amplitudes, and a number of loudspeakers (L1 to Lk) placed to broadcast said early reflected energy into the room.
