I took the recording into pro tools. Its fine!
It goes high, but doesnt clip or distort. dropping "erm" by 4 db makes it fit well with the other material.
If its sounding bad your end id suggest i ts your soundcard or speakers that cant cope.
I brought the clip into audacity for a quick look and listen. Yes, there is some distortion on the word "um". I'm not going to assign any blame on your sound guy because I don't know what his setup procedure for this was. But I will say this - this is the same kind of distortion that I run into with the Zoom recorders when I feed line level signals into the line level inputs. Distortion occurs only on the loudest transients even though the levels appear to be fine on the recorder display. I set my reference tone at -20 at the recorder, I run the mic through my Sound Devices 442 (with limiting set at +14). I know the set up is right and yet I get this type of distortion. However, if I run a mic level signal into the mic level inputs of the Zoom (reset reference tone at -20, microphone running through 442 with limiter set at +14) this distortion goes away.
The DPA 4060 is a very good mic - not much limitation with it. But I'm not a big fan of the Zoom recorders for this very reason.
