Hi All Sampo, I guess that in this case we are talking about the hiss that originates from the amplifier stages of the microphone. Of course the acoustic noise into the capsules from Brownian movement adds to this, but that part is much smaller.
The microphone self noise (or hiss, if you like) was the first reason, why I decided to stop using the Soundfields (ST250 and MK IV and V at that time) for radio drama. The hiss from the mic was simply too audible for the scenes. Possibly the way that the Finnish actors use their voice and dynamics is different to the declamating yelling that I hear in radio drama from many other countries. :-) I ended up using the Soundfield only for background atmospheres that I recorded separately. Many Sursounders may not be aware that there are practically at all multichannel noise reduction systems available. They are all stereo, and can process mono. The same thing was true with multichannel equalizers and dynamic processors at the time, when I would have use of them in the nineties. Because 5.1 systems became popular, there now are EQ:s and dynamic processors. But no noise reduction systems. Just one more note Garth; When you have denoised the files, check that their length bitwise is the same as it used to be. At least in the large scale you are on the safe side then. Of course the phase may deviate during the file run, but I don't think that won't happen.
