What you did seems very interesting, but I don't think it
accomplished what I was talking about.    (02)

What the hall was supposed to be doing is to take a sound from
an independent source (such as a musical instrument) and echo
it a quarter tone lower.    (05)

But I gather that you produced two separate sounds that were very
close together -- thereby creating a beat frequency (X-Y), where X
was the frequency of one sound and Y was the frequency of the other.    (06)

By the way, that URL points to a web page:    (07)

But I couldn't find the actual sound track.  What is its URL?    (09)
