Please feel free to outline where you think the errors lie, Len. We have certainly had discussions but I don’t recall you pointing out errors other than your assertion that preamp gain would have a negative effect on the noise performance of your microphones, which we proved to be incorrect by repeating the measurement and two different gain settings. You will find both recordings in the Reaper project and you will see both have precisely the same noise floor in the silence preceding the music. A much higher noise floor than any of the other mics tested, I might add, making the effect more obvious in comparison to the low level background noise of the studio and the -127 equivalent input noise of the zoom f8 preamp.
It’s a pretty straightforward test - Record the same input signal, kindly produced by Steven Boardman, at the same input gain on multiple microphones. Then loudness match the recordings to play back at the same level and listen to the results. You also suggested the test would only be fair if we used bilateral ambisonics, which is frankly nonsense. I look forward to your response and the input of other experts to identify where we may have made errors. With kind regards.
