Sliding FFT (Maximum Overlap), Any Window, Zero-Padded by 5

• Perfect reconstruction (always true when hop-size = 1)
• Oversampled by :
  • = window length [time-domain oversampling factor]
  • 5 = zero-padding factor [frequency-domain oversampling factor]
• Excellent channel isolation (set by window sidelobes)
• Extremely robust to filter-bank modifications
• No aliasing to cancel
