 the generated signal. We would like to calculate this step value as a function of the desired frequency. In order to do the conversion, we need to know the sampling frequency. It is available in the standard library as <code>ma.SR</code> and will be setup at start time by the underlying audio layer. To use this standard library we add the following line to the program: <code>import("stdfaust.lib");</code>.</p>
<p>Suppose we want our phase signal to have a frequency of 1 Hz, then the step should be very sma
