Eric,
In your intial reponse to Rich you wrote, "The last piece of info is
that they asymmetry is audible. If you invert the waveform, it will
sound different than if not inverted, at least with low-frequency
sounds and with headphones."
Is it possible to invert a waveform for listening purposes outside of
a research lab, that is, on a home PC? If so, what kind of software
is required for the project?
Also, Eric, would care to expand your comment that "it will sound
different . . . at least with low-frequency sounds and with
headphones"? Why relative to low frequencies as opposed to the mid
and higher frequency ranges? And with earphones as opposed to
speakers? Is is because the audible differences are sufficiently
subtle that earphone usage is required for detection?
By the way, this for me has been a tremendous thread to follow. When
postings get into acoustical aspects I really start to groove.=20
Anyone know of a Yahoo!Group and/or any other interactive Website
that focuses upon acoustics/psychoacoustics? Thanks.
Scott
