Daft frequency/period question.

    Ok I know I should be able to figure this out but I'm having a dumb afternoon.

    I've got an array of values in a wavetable, (comupter stuff) 512 in all making up the values in a sine wave. I'm reading through that array once every 512ms, one step every 1ms.

    Now, I want to be able to put in a value of 1 and the table to be read every 1 second, 1Hz.

    So the period of the wave is 512ms, how often should my program step through each value (512) in all so as to read the array every 1 second? :confused:

    Do you mean (1000 / 512) = 1.953125 ms for each step?
