Dear List,

It is great to see freeware such as Armadillo - James Beauchamps et al.
This is just the freeware I have been looking for - but I don't have a Mac.
Can anyone recommend freeware for a Intel PC that does a similar job,
preferably windows based? I am using the software for spectral analysis of
sounds in relation to localisation cues and HRTF's.
