This repository comprises resources related to the 4th ambisonic order microphone array prototype that we created for the Insta360 Pro camera. Here is a demonstration video of it: https://youtu.be/5jAu47l2WaY. Other designs for ambisonic microphone arrays are found in this repository.
The folder 3d_model comprises resources related to the design of the microphone mount. The folder signal_processing comprises resources related to the processing of the signals that the microphones of the array capture. You will also find the raw signals there from which the above demonstration video was created. The scripts have been created for MATLAB. Minor tweaks are required for making some them work on Octave. We'll provide that shortly. See this commit to get an idea of what kind of edits are required. The MagLS rendering has not been tested with Octave. But we'll do that shortly, too.
When using these resources, please cite the following paper in which we presented the prototype for the very first time:
