Observational evidence for black hole spin down has been found in thenormalized light curves of long GRBs in the BATSE catalogue. Over the duration$T_{90}$ of the burst, matter swept up by the central black hole is susceptibleto non-axisymmetries producing gravitational radiation with a negative chirp. Atime sliced matched filtering method is introduced to capture phase-coherenceon intermediate timescales, $\tau$, here tested by injection of templates intoexperimental strain noise, $h_n(t)$. For TAMA 300, $h_n(f)\simeq 10^{-21}$Hz$^{-\frac{1}{2}}$ at $f=1$ kHz gives a sensitivity distance for a reasonablyaccurate extraction of the trajectory in the time frequency domain of about$D\simeq 0.07-0.10$ Mpc for spin fown of black holes of mass $M=10-12M_\odot$with $\tau=1$ s. Extrapolation to advanced detectors implies $D\simeq 35-50$Mpc for $h_n(f)\simeq 2\times 10^{-24}$ Hz$^{-\frac{1}{2}}$ around 1 kHz, whichwill open a new window to rigorous calorimetry on Kerr black holes.
