The Problem with 192/32bit Recordings Edit: this not only applies to 192/32 recordings, but additionally to 24 bit multi ADC devices recorded at 192 like the Sony D100 or certain Sonosax recorders   One of the things we refer back to most on the field recording slack is issues recording at 192/32bit If you've ever run into this issue on 32bit recordings, you might have noticed weird bursts of noise above 50khz  Pictures via Aaron Brown How does 32bit recording work? In a single ADC 24bit recorder the pipeline works kinda like this: The microphone creates a very small electric signal that's fed into the recorder That signal is adjusted by a potentiometer (your gain knob) That signal is conditioned by a preamp That amplified signal is converted into a digital signal by an ADC (Analog Digital Converter) A 32bit recorder works like this (using the mixpre series as an example) The microphone creates a small electrical signal fed to the recorder That is amplified through 3 preamps Th

Over the years, we've had a number of really interesting topics talked about on the field recording slack that get referenced back to off and on but never have a permanent home. I've done a little work here and there trying to do things like give the technical documents a space on google drive, but I wanted to start a blog so I have one concrete place for people to refer to for things like mic shoot outs or technical information and ideas I refer back to. Take a look around and hopefully take away something good!
