Converting Propagation Distance to Delay Length
We may regard the delay-line memory itself as the fixed ``air'' which
propagates sound samples at a fixed speed (
meters per
second at
degrees Celsius and 1 atmosphere). The input signal
can be associated with a sound source, and the output signal
(see Fig.2.1 on page
) can be associated with
the listening point. If the listening point is
meters away from
the source, then the delay line length
needs to be
