Impulse Response Measurements Using All-Pass Deconvolution
David Griesinger · International Conference on Test and Measurement · 1992
A method of measuring impulse responses of rooms will be described which uses time reversed electronic reverberation from a single pulse as the excitation. The room response, recorded on DAT, is decoded by playing the tape back through the reverberator. The output can be heard, recorded, or analyzed. The method improves S/N by 20 dB and can be implemented with approximately 14 multiples/sample on a PC.
