Reducing time in acoustic impulse response measurements using exponential sine sweeps

Measuring the audio impulse response is a very common and important operation in every characterization of acoustic systems and sound fields. For the past decade, sine sweeps are the most employed signals for achieving this goal both by researchers and the audio industry. When the application requires a huge number of impulse responses to be measured, every second that can be saved for a single measurement counts. This article proposes and implements an artifice in the method suited for reducing the time of measurement.
