Dear Auditory List members,

We have recently completed an extensive set of head-related transfer
function (HRTF) measurements of a KEMAR dummy head microphone. The
measurements consist of the left and right ear impulse responses from
a Realistic Optimus Pro 7 loudspeaker mounted 1.4 meters from the
KEMAR. Maximum length (ML) pseudo-random binary sequences were used to
obtain the impulse responses at a sampling rate of 44.1 kHz. A total
of 710 different positions were sampled at elevations from -40 degrees
to +90 degrees. Also measured were the impulse response of the speaker
in free field and several headphones placed on the KEMAR. This data is
being made available to the research community on the Internet via
anonymous FTP and the World Wide Web.

The data is organized into two tar archives, accompanied by a document
(Postscript and text) describing the measurement technique and data
format. To access the files via FTP, connect to "sound.media.mit.edu",
login as "anonymous", and give your Internet address as a password.
The files may be found in the directory "pub/Data/KEMAR". There is a
README file describing the contents of this directory.
