"In early April we publicly demonstrated the production version of the A16 for the first time at CanJam LA. This gave us an opportunity to operate the A16 in a more real-world environment, and also gave attendees an opportunity to check on our progress. The operating A16 firmware for this show was modified so as to streamline the measurement procedure to ensure that more people could get a proper demonstration. This entailed by-passing routines and hard-coding parameters that might normally be used to more deeply personalise the virtualisation. Therefore this demonstration didn’t fully exercise the firmware.
On the positive side the 9.1.6ch Dolby Atmos virtualisation worked well, with the extra wide and height channels making a very noticeable improvement in the acoustic immersion, whilst the overlapping measurement technique kept the measurement time to a reasonable length. The file management routines for the internal memory and external SD card also worked well.
On the negative side we encountered intermittent problems with the head-tracking and more prolonged problems with the binaural microphones. The head-tracking issue caused the virtualisation image to appear offset from its true position, and the microphone problem effectively shut down the demo for a period of a few hours.
Since returning we have redesigned the head-tracking firmware, improving its stability and allowing us to field-update the code from the A16. This ensures that the performance of the head-tracker can be improved over time. We believe that static caused the problems with the binaural microphones in LA, and in future it may be necessary that the user wear a grounding strap during the measurement procedure.
We’re now back working on the A16 operating firmware, in particular on the control of the MDS DSP module that decodes and renders the Dolby Atmos and DTS:X algorithms. The recent upgrade of this code to 9.1.6ch for Atmos has increased the complexity and scope of the necessary control and management routines. As well as resolving the software issues at this moment, we our currently working on getting software ready for the Dolby compliance test. We estimate 3-4 weeks for the software to be complete, then a further 4-6 weeks for Dolby to complete Atmos certification. This implies that shipping will not commence before August.
The Exchange website is developing more smoothly. We our currently working on the account administration, and this is close to completion. Roles and security will be next which includes administration functions such as adding files from studios, log files for registering user’s hardware and minor modifications to the shopping cart. Once this is complete the Exchange site will be ready to launch.
