data T rate amplitude body

A signal value 0.5 at global amplitude 1 and signal value 1 at global amplitude 0.5 shall represent the same signal. Thus it is unsafe to observe the amplitude.

ToDo: Maybe we should support zipped signals with mixed amplitudes, e.g. T rate (amp0, amp1) (Sig.T (y0,y1)) in order to be compliant with the way Causal and Wave.Controlled handle multiple sources. However, this is dangerous, since T rate amp (Sig.T (y0,y1)) might be used for stereo signals. Of course, for stereo signals Stereo.T should be prefered.

Cyclic nature such as needed for Fourier transform must be expressend in the body. It would be nice to use the data type for waveforms, too, but for waveforms the rate parameter makes no sense.

Take a scalar argument where a process expects a signal. Only possible for non-negative values so far.
