PD uses 32bits natively (unless you compiled it especially for 64bit), 
so the iem16 stuff would halve the amount of RAM required, but at the 
slight expense of audio quality (doesn't matter if your files loaded 
into tables are 16bit, but for delay lines you might notice the 
decreased dynamic range).

4 bytes per sample * 44100 samples per second (or whatever the sample 
rate is) for 32bit audio.

Plus a small constant (I hope) overhead for bookkeeping for each object.
