Reverberation Analysis via Response and Signal Statistics

This work examines statistical quantities (i.e. kurtosis, skewness) of room transfer functions and audio signals (anechoic, reverberant, speech, music). Measurements are taken under various reverberation conditions in different real enclosures ranging from small office to a large auditorium and for varying source receiver positions. Here, the statistical properties of the room responses and signals are examined in the frequency domain. From these properties, the relationship between the spectral statistics of the room transfer function and the corresponding reverberant signal are derived. This work is inspired and dedicated to the memory of Manfred R. Schroeder.
