In the previous posts, I mentioned that I need to design a listening test for evaluating spatial audio quality. Some elements may affect localisation in the listening test. Today, I am going to introduce some technologies that may use in my listening test and the word process so far.
Several technologies may use in the listening test
OptiTrack [1] creates a software name is Motivate can provide an optical motion tracking system that enables tracking multiple people in much larger spaces for a collaborative VR experience. Actually, I may use this software in my listening test to detect localisation effect if the Covid-19 did not appear…..
Max:
Max can create multiply channels for ambisonic. Max can be the Listening test software for loudspeaker presentation was created using the visual audio programming environment Max. Here is a practicing video:
Reaper :
The Reaper is a DAW (digital audio production application for computers)software, it can combine Listening test software for the audio engine.
It can also can encoder ambisonics through the plugins, such as ATK, Audio Monitor VST with Ambix_rotator_o1 VST.….

VR Videos:
Consider the listening test’s purpose(evaluate audio quality in different contexts), I need to find some VR videos. In the beginning, I consider creating VR videos. However, I realize it is impossible because the project only has 11 weeks. I have to manage time properly, There is pointless wasting time in unfamiliar fields. I will put more time into Audio parts.
I will talk with my supervisor, may the industry partner can offer some videos. Moreover, I have already found some VR videos and contact their author. I hope I can get the Videos to use soon.
Special situation
Unfortunately, this year is very special due to Covid-19. My final project may stay home to complete, a lot of tools like (Neumann KU100) can not be used… So, I may use Reaper and send tester my project(combine ambisonics with video).
