Multi-channel Late Reverberation Power Spectral Density Estimation Based on Nuclear Norm Minimization

• Reverberant acoustic systems with a single-source and 4 microphones

  Acoustic system 1: T₆₀ = 0.61 s, source at θ = 45°

  Acoustic system 2: T₆₀ = 1.25 s, source at θ = -65°

  WOLA framework with a frame size of 64 ms and an overlap of 75%
