[generated using 8 bits of randomness, using a phase of 0.0137; any non-zero phase should give similar results]
[amplitude = noise(i * step * freq + phase)]

The perceived frequency is frequency * step_size. These images were generated with step_size=1 (i.e. each pixel is one step apart). Of course, if your step size is A, divide the values in the table by A to get the same result.
