Re: [Sursound] RIR measuring, how to capture a higher order Ambisonic room responce?

Most of this I knew beforehand... The robotic arm is a bit on the short side to manipulate my microphones so as to get measurements at high elevations with respect to the horizontal plane (ie: can't tilt it enough without changing the location of the center of the array - or, with a different initial pose I can get high elevations for one of the hemispheres but not for the other). Shorter microphones should not have this problem. And the wrist servo has only 300 degrees of rotation which makes it not so useful to rotate the microphone for measurements. So I modified it. I removed the gripper as I do not need it (which shortened the wrist which means I can get better elevation coverage) and replaced the wrist rotation servo with another one that has 360 degrees of rotation (so I can use it to rotate the microphone for measurements - this required me to design and 3d print a connection block). And modified the software that controls the arm to take these changes into account. Looks more promising now... Having played with it for a bit I know now it would not be out of the question to design a more suitable arm with the same type of servos and control board, it is a very flexible system. I could even lengthen the arm segments of the one I have, but enough modding for now... :-) -- Fernando ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.

Any assistance in creating JS code to interface to reaper rotational vst's from our host module would be a great bonus : -) I will try to update my earlieriest USB version based on bno055 and arduino328p which is 3,3volt with a usb serial interface.

Re: [Sursound] Open HeadTracking Initiative OHTI - Release announcement
This is great Bo-Erik! I will definitively look into adding support to AmbiExplorer for this tracker. I found a couple of sources online where to buy the components but I was wondering if there's any particular breakout boards for those ICs that you would recommend (both for the F52832 BT/SoC and the BNO055 IMU). I would like to also look into designing a 3D printable enclosure for it. Cheers!

[Sursound] Open HeadTracking Initiative OHTI - Release announcement
I want to present OHTI, a combination of open Software, Firmware and HW for listening to Ambisonic recordings in Ambix format and with a plan for listening to channel based Audio in the future, The Manifesto at https://github.com/bossesand/OHTI/blob/master/OHTI%20v.14.doc describe the current status and the plans for the future on a technical level soutable for sursound members. All the software and descriptions of needed HW is available at https://github.com/bossesand/OHTI The Headtracker is using BLE for communication with the host software and is built with nrf52832 and BNO055 for drift free headtracking. All of the host software is JS/node.js or JS/HTML5 based to allow it to work on many different platforms. We have in this alpha release Ambisonic 2 players implementations with headtracking activated using Omnitone or JSAmbisonics. We also describe how to convert a personal HRTF SOFA file for use with each of the players. We have tested the implementations on Linux (Ubuntu), OSX and Win10 with HTML5 capable Browsers like Chrome and Firefox. We have received support or assistance from a number of members on the sursound list since the slow start in 2014. We hope for continued support and assistance in this effort to make headphone sound more realistic ( out of the head ) and promote surround sound for music and not only in VR context. We also hope that you can make it possible to use this headtracker with other Ambisonic Soundfield Binaural decodes. We do of course also appreciate any corrections or further assistance in development of this concept.
