DesiredPhase Signal

1.I.R. resembles decaying noise

•Not too sparse or repetitive

2.Sub-channel frequency resolution

•The phase increments should provide additional frequency resolutionbeyond that of the center frequencies of the spectral bins

•We would like a piano note’s reverb to be at the same pitch as theoriginal note...

•If the phase signal can’t help with the frequencyresolution, we may haveto use long FFTs
