Could nightclub DJs soon be out of a job? To avoid silence between tracks,
they cue up one recording while another is playing, and then fade between the
end of one and the start of the next. Thomson-Brandt of Hannover has a system
that does this automatically (EP 93 2 157). A CD player runs faster than normal
to feed the music into a buffer memory, while it is read out at normal speed. So
the buffer can detect the end of a song before it is played. With several
seconds of the first disc left to go, the second CD starts playing and fades
up.
