Add a delayed, attenuated version of a sound to the original.

Cheers,

is the equation like this:

y[n]=x[n]+ a*(x[n-d])

where:
y[n] is the output
x[n] is the input
a is att
d is the delay

Is this right?

Sounds plausible to me. Of course, real echoes may have a frequency
response component as well as a delay and gain component. Sorry, but I
don't have any code.

Cheers,
