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: http://www.hoertechnik-audiologie.de/downloads/PureMeasurement/
