Evaluation of Artificial Reverberation Decay Quality

Document Thumbnail

Three different methods to evaluate artificial reverberation decay quality are investigated (monaural attributes). The first method is based on evaluation of the autocorrelation function F(t) in octave bands. The temporal diffusion, defined by Kuttruff as TD = F(0)/ max {F(for t greater than 0)}, is proposed as a simple engineering metric. The second method employ evaluation of the short time energy in the impulse response filtered in octave bands. A sliding 30 ms window was employed to calculate the short time energy in the filtered room impulse responses (exponential decay was compensated by an exponential increasing factor). The last method was a modified version of the Kohlrausch spectral stationarity test called Reverb-prints.
