We have computed the spectrum and energy of gravitational radiation from a "point test particle" of mass m falling radially into a Schwarzschild black hole of mass M≫m. The total energy radiated is about 0.0104mc2(m/M), 4 to 6 times larger than previous estimates; the energy is distributed among multipoles according to the empirical law E2l-pole≈(0.44m2c2/M)e-2l; and the total spectrum peaks at an angular frequency ω=0.32c3/GM.
