In a nuthsell, i-rate vars are constants, but can be updated on each new instance of an instrument, k-rate values are scalars which are updated every ksmps samples, and a-rate vars are blocks of ksmps samples. So the output of follow2 is a block samples. If you pass it through a tone you can smooth the signal. Here’s a simple example.
instr 1
a1 diskin2 "voice.wav", 1, 0, 1
a2 follow2 a1, .1, .1
a3 tone a2, 10
;outs a1, a1
fout "followOut.wav", 4, a2
fout "followOutTone.wav", 4, a3
endin
