This year ImmersAV (pronounced im.mer.sav) Technology was invited to participate
in AXPONA, Audio Con 2015 in Chicago. This annual event features an exhibition of
high-fidelity, high-end audio products for the casual music lover up to the serious
audiophile. A major feature of the show was the Headphone Expo, where attendees
could audition headphones products from major manufactures. At this year’s
conference, ImmersAV Technology produced a live jazz quartet concert – John
Moulder & Friends – featuring a number of Chicago’s greatest performing artists.
The concert was free for all attendees of the show. This concert gave ImmersAV
Technology an excellent opportunity to showcase their proprietary and patented
recording and Binaural Crosstalk Cancellation (CTC) filter technology. Concert
attendees were able to switch between the live performance and the ImmersAV
audio mix while seated in the audience. A high performance Sennheiser wireless
headphone system was provided for all attendees. Casual music fans and
audiophiles alike enjoyed the performance, paying special attention to this unique
sound presentation that many said, “Made us feel like we were literally standing
right among the musicians.’
The John Moulder & Friends recording is now available for purchase as a download
($25) or on a USB memory stick ($30). For details go to www.immersav.com. The
production includes four versions of each of four songs; a 24/96kHz high-resolution
headphone and loudspeaker version with 1080p HD Video, and a 320 kb/s AAC
headphone and loudspeaker version with 720p HD Video. The loudspeaker versions,
processed with precision 24-bit, 96kHz HRTF-based Crosstalk Cancellation Filters,
are for traditional two-speaker stereo listening with spatial audio matching the
headphone spatial experience. The 320 kb/s AAC versions are for convenient
viewing on smart phones and tablet computers.
Audio pioneer and Engineering Producer, Robert Schulein along with Signal-
Processing Researcher/Designer, Dan Mapes-Riordan, founded ImmersAV
Technology in 2010. Their objective was to create a practical 3-D immersive
audio/visual experience for consumers for enjoyment on the most common forms of
playback technology – headphones and traditional stereo loudspeakers. To make
this happen new production tools and recording techniques were developed.

Unique to the new technology and know-how involved in creating these productions,
no additional audio/video product purchases for consumers are necessary. The
playback quality goes up with the quality of the playback equipment. We believe
that we have achieved our goal of offering a true “You are there’ audio/visual,
immersive playback experience.
Engineers have been working on the optimization of acoustic crosstalk filters for
loudspeakers since the mid 1960s, but we believe that we have reached a degree of
perfection never heard before using proprietary DSP techniques, refined by our
ability to compare loudspeaker playback with our original binaural headphone
productions.
