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 "", 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.
