Energy Decay Curve
For measuring and defining reverberation time , Schroeder
introduced the so-called
energy decay curve (EDC) which is the tail integral of the squared impulse
response at time :
Thus,
is the total amount of signal energy remaining in the
reverberator impulse response at time . The EDC decays more
smoothly than the impulse response itself, and so it is more useful
than ordinary amplitude envelopes for estimating .
