If we want to simulate this in a digital form, we need some kind of digital tape
loop. Because of the discrete nature of digital, the digital tape loop will hold
a finite number of audio samples, and these samples will be recorded and
read at the audio sampling rate:

A natural choice for a digital tape loop would be an array, the size of the array
being equal to the number of samples recorded in the whole loop.
In an analog tape delay, the delay time depends on the distance between
the record and playback heads and on the tape speed. Usually the distance
between the heads is fixed and the tape speed is variable. It is done that way
for obvious technical reasons: it’s much easier to vary the tape speed than
the distance between the heads. In the digital case, it’s just the opposite,
because varying the tape speed means performing sampling-rate conversion
between the digital tape and the output, while varying the distance between
the heads is relatively simple, so that is what we are going to do:
