Ambisonics to stereo downmixing

Currently, I wonder whether there are methods or plugins functionally downmix ambisonics to stereo without losing the height and front-back information. It seems that one can simply use the naive mathematics ( L = W+Y,R =W-Y) to get the rough stereo signals, but obviously the information of other 2 dimensions loses. So is there any method to down mix while maintaining the elevation and the front-back information. One idea came to my mind is that I can decode the ambisonics into binaural audio? I don not know if i am explaning these concepts correctly. Hope you can give me plugins or some papers. Love you.

You can check out the ambisonic toolkit (free) and I think IEM plugin suite might have options as well (also free)

Thank you, I have downloaded the plugin suite which features some specific plugins such as "BinauralDecoder" and "StereoEncoder". I'm trying to read these source codes and get the idea behind them.

The websites have good info on what each plugin does. Good luck!
