Abstract: Traditional room-equalization involves exciting one loudspeaker at a time and deconvolving the loudspeaker-room response from the recording. As the number of loudspeakers and positions increase, the time required to measure loudspeaker-room responses will increase. In this paper, we present a technique to deconvolve impulse responses after exciting all loudspeakers at the same time. The stimuli are shifted relative to a base-stimuli and are optionally pre-processed with arbitrary filters to create specific sounding signals. The stimuli shift ensures capture of the low-frequency reverberation tail after deconvolution. Various deconvolution techniques, including with and without spectrum-shaping filters, are presented. The performance in terms of log-spectral distortion, as a function of stimuli length and shift, and impulse and magnitude response error plots for the Multichannel Acoustic Reverberation Dataset at York (MARDY) are presented.
