[PD] testing reverbs

[Conor J Curran]

Hi folks,
Does any have any pointers as to how to test reverbs within Pd.
I have compiled a basic shroeder reverb with SndObj and was hoping to
test the reverb in PD.

What I gathered I need to set up an white noise burst of around 50ms run
it through the reverb and perform a spectral analysis on the response. 
Are there any PD objs that can quicken this objective?

regards,
Conor
