Should be not. So, once more:
The sample interval here is 1r8000 sec (=8kHz
sampling). For Ian, the one-second signal is "194.14 sine waves",
and for direct treatment of "sin(x)" function with 1&o., the "x"
values ("points where the samples are taken") for the periods have
to be measured in the radians:
x =. (194.18 * 2p1 ) * (i. % <:) 8000
At every sample point, the sample value ("sample") will be the
sine value or some scaling thereof:
samples =. ... 1 o. x
Less confused now?

against my tuning fork. You might get one before posting, too.)
