I record the 4-channels of Ambeo onto a Sound Devices 664, resulting in a 4-channel polywav file. I can take that audio file and directly replace the audio from the GoPro, though I typically do some post production tweaking. The audio from the Ambeo is incomparably better than the native audio from the GoPro.
Sennheiser offers a free download A-B converter, to convert the A-format output from the Ambeo to B-format Ambisonic compatible. I use Harpex, as it sounds better and offers more options.
