Perceptual Similarities between Artificial Reverberation Algorithms and Real Reverberation

This paper presents a study evaluating the perceptual similarity between artificial reverberation algorithms and acoustic measurements. An online headphone-based listening test was conducted data were collected from 20 expert assessors. Seven tested in test, including Dattorro, Directional Feedback Delay Network (DFDN), (FDN), Gardner, Moorer, Schroeder algorithms. A new Hybrid Moorer–Schroeder (HMS) algorithm included as well. solo cello piece, male speech, female singing, drumbeat rendered with seven three different times (0.266 s, 0.95 s 2.34 s) conditions. The based on Multiple Stimuli Hidden Reference Anchor (MUSHRA) paradigm. reference conditions consisted of same audio samples convolved measured binaural room impulse responses (BRIRs) times. anchor dual-mono 3.5 kHz low pass filtered audio. scored scale zero to hundred. Statistical analysis results shows that Gardner HMS are good candidates for exploration Augmented Reality (AR) scenarios future research.
