So it is not related to the Python version since this is 3.7 now? (That would have been very weird anyways, if all other packages are identical). `Max relative difference:...

I'm pretty certain this should solve it. ```python # part of parallel render_bsdm: def _render_bsdm_sample(i, p, phi, theta, hrirs): h_l, h_r = hrirs[hrirs.nearest(phi, theta)] # global shared_array with shared_arr.get_lock(): #...

Yes. I see the documentation is confusing in regards of the lock. The way that I understood it so far is, that it provides lock functionality for synchronized access, but...

Windows potentially (by default) follows a different mechanic of spawning child processes. I am not sure why this would influence the lock though, https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods However, I did not really understand...

Actually, https://docs.python.org/3/library/multiprocessing.html#all-start-methods (**Explicitly pass resources to child processes**) explains that this might actually be cause by the different process spawning on Windows. I would still expect my suggested way above...

To clarify first what you are looking for. In the simulation of what kind of sound field are you interested in: - anechoic sound field in Spherical Harmonics? - anechoic...

We recently added the option to decompose and render real spherical harmonics, see [Exp4](https://nbviewer.jupyter.org/github/AppliedAcousticsChalmers/sound_field_analysis-py/blob/master/examples/Exp4_BinauralRendering.ipynb). I am not super familiar with the different conventions, so I would have to check whether...

Thanks Chris for these references. 👍 I also noticed that our versions leads to a slightly different result compared to your implementation. However, I did not have the time investigate...
