I'm not sure what you mean by IR or phase of a "signal", usually it's some kind
of transformation system like a filter, whose IR or PR people are interested
in.

Anyway for measuring filter phase and frequency responses, the filter-graph
abstractions in the Pd docs can be useful. Check out for example
H10.measurement.pd and replace the [bp~] with whatever you would like to
measure. It's using a swept-sine method. 

Pure Measurement is a complete toolkit written in Pd for these kinds of things:
