.TH STEP 1 "1 September 1993"

.SH NAME
step \- generate a step waveform.

.SH SYNTAX 
step [options]

.SH DESCRIPTION
Generate a step up or down of given amplitude at a given shift from the origin
(start of waveform), and write the resulting waveform on the stdout in the
given datatype.

.SH OPTIONS

1. shift

The position of the step (up or down) relative to the start of the waveform.
The shift can be in samples (no units) or can take time units
(using the samplerate option).

2. amplitude

The height of the step.

3. polarity

The direction of the step: up (zero before the step and `amplitude' after)
or down (`amplitude' before the step and zero after).

4. duration

The duration of the output wave, including the shift to the step.
The duration can be in samples (no units) or can take time units
(using the samplerate option).

5. type

The output datatype. This may be any of: char, short, int, float, double,
ascii (meaning one ascii number per line).
